The Thomson TS880 is Thomson Power Systems' mission-critical automatic transfer switch, covering 800A to 4000A with insulated-case power switching devices. Available in both 3-cycle and 30-cycle withstand configurations, it serves data centers, hospitals, and facilities where power continuity and selective coordination are non-negotiable.
The TS880 uses the TSC 900 controller as standard — a 7-inch color touchscreen with front-panel programming, comprehensive event logging, and Modbus communication. All configurations (open, closed, soft-load, bypass-isolation, service entrance, dual source) are available across the full 800-4000A range. The 30-cycle design shares its platform with Thomson's UL 1558 low-voltage power circuit breaker switchgear.
The TS880 bypass-isolation uses draw-out transfer power switching devices with key interlock mechanisms, mounted in separate barriered compartments from the ATS. The procedure:
Transfer load to the preferred source via the bypass handle
Isolate the ATS from both sources using the key interlock mechanism
Draw out the transfer switching devices for inspection or replacement
Service contacts, mechanisms, and controller with the load running on the bypassed source
Return draw-out switches, release interlocks, and return to automatic operation
The break-before-make bypass design prevents utility and generator paralleling under any circumstance. For units with closed-transition capability, the bypass can be operated in make-before-break sequence at the operator's direction.
The TS880 CTTS uses electrically interlocked insulated-case power switching units with the TSC 900 controller's built-in sync check relay. The controller monitors voltage differential and slip frequency between sources. When both are within threshold, it initiates a closed transition lasting less than 100ms. If the paralleling timer exceeds its limit, extended paralleling protection opens the other source within 500ms.
Soft-load transition is available as an additional ordering option for process loads requiring gradual transfer ramping.
We service Thomson TS880 units in Bay Area data centers and healthcare facilities. The insulated-case switching mechanism is extremely robust at these current levels — contact life far exceeds contactor-based alternatives in this amperage class. Annual thermographic scanning under load is essential for all frames, not just the larger ones — at 800A+, any loose busbar connection generates significant heat.
The 4000A bypass-isolation units are physically massive — at 92" x 96" x 90" and up to 7,500 lbs (4-pole), they require rigging equipment and careful access planning. We've seen installation delays on retrofit projects where the freight elevator couldn't accommodate the weight or dimensions. Specify access requirements during design to avoid costly field surprises.
The TSC 900 touchscreen controller is a significant upgrade from the TSC 7320 used on the TS870. The 7-inch color display makes programming and troubleshooting faster during service calls, and the event logging with time/date stamps provides valuable forensic data when investigating transfer events.
Frequently Asked Questions
What amperage range does the Thomson TS880 cover?
The TS880 covers 800A through 4000A in 3-pole and 4-pole configurations. Standard frame sizes are 800A, 1000A, 1200A, 1600A, 2000A, 2500A, 3000A, 3200A, and 4000A. The voltage range is 208-600V for three-phase, 3 or 4-wire systems at 50/60 Hz.
What are the 3-cycle withstand ratings?
All frames 800-4000A share the same 3-cycle withstand: 100,000A at 240V, 100,000A at 480V, and 85,000A at 600V. With optional overcurrent trip units, interrupting ratings match these withstand values.
What are the 30-cycle withstand ratings?
The 30-cycle models provide 85,000A 3-cycle at all voltages up to 600V, plus 65,000A 30-cycle at all voltages up to 600V. For power switching devices without trip units, withstand is 65,000A at both 3-cycle and 30-cycle.
What controller does the TS880 use?
The TS880 uses the TSC 900 controller as standard, featuring a 7-inch color touchscreen with front-panel programming, 8 programmable output contacts, RS232 Modbus via the GHC (Graphical Human Controller), optional Ethernet Modbus TCP, USB ports, and comprehensive event logging. The TSC 900 includes built-in sync check relay for closed-transition applications.
Does the TS880 offer bypass-isolation?
Yes. The bypass-isolation configuration uses draw-out transfer power switching devices with key interlock mechanisms, mounted in separate barriered compartments. All external power cabling connects in the bypass compartment. The break-before-make design prevents utility and generator paralleling under any circumstance. Bypass units with closed-transition may be operated in make-before-break sequence at the operator's direction.
What are the physical dimensions?
ATS-only (NEMA 1): 800-2000A share one cabinet at 91.5 x 36 x 42 inches (1,500 lbs); 2500A is 91.5 x 36 x 60 inches (1,800 lbs); 3000/3200A is 91.5 x 36 x 60 inches (2,000 lbs); 4000A is 91.5 x 48 x 72 inches (3,000 lbs). Bypass-isolation units are significantly larger — the 4000A bypass unit measures 92 x 96 x 90 inches and weighs 6,500-7,500 lbs depending on pole count.
What configurations are available beyond standard ATS?
Service entrance (SE) with integrated overcurrent protection. Bypass-isolation with draw-out switches. Closed transition (momentary, <100ms). Soft-load transition. Dual utility control (DU). Dual standby generator (DSG slave ATS). Dual prime generator (DPG). CSA Type B with integrated overcurrent and ground fault protection. 30-cycle versions of all configurations.
How does the TS880 compare to the ASCO 7000 Series?
Both target mission-critical applications. The TS880 starts at 800A with insulated-case switching and offers both 3-cycle and 30-cycle models. The ASCO 7000 starts at 30A with contactor switching. The TS880's 30-cycle design shares its platform with Thomson's UL 1558 switchgear, enabling seamless integration into paralleling switchgear packages. ASCO has broader distributor availability; Thomson typically offers more competitive pricing on large-frame mission-critical units.
What seismic certifications does the TS880 have?
The TS880 is seismic certified per IBC 2012 Section 13, Occupancy Category IV, ASCE7-05 Region 3 (minimum Ss=200%), and OSHPD certified. The OSHPD certification qualifies it for California hospital installations where healthcare-specific seismic requirements apply.

Key Terms
Insulated-case switch
Power switching device with molded insulation surrounding the contacts and mechanism. Used in the TS880 for high withstand ratings. The 30-cycle design shares the same platform as Thomson's UL 1558 low-voltage power circuit breaker switchgear.
Bypass-isolation
Configuration with draw-out transfer switches and key interlocks in separate barriered compartments. Allows maintenance personnel to isolate and bypass the ATS without interrupting power. Break-before-make design prevents source paralleling.
3-cycle vs 30-cycle withstand
3-cycle (50ms at 60Hz) is standard. 30-cycle (500ms) provides additional margin for selective coordination in mission-critical facilities. The 30-cycle design uses insulated-case power switching devices rated 800-4000A.
TSC 900 controller
Thomson's standard controller for the TS880 with 7-inch color touchscreen, front-panel programming with password security, 8 programmable output contacts, RS232 Modbus via GHC, optional Ethernet Modbus TCP, USB ports, and event logging with time/date stamping.
Soft-load transition
A controlled ramp transfer that gradually shifts load between sources, minimizing transient voltage and frequency disturbances. Available as an ordering option on the TS880.
CSA Type B
TS880 option integrating overcurrent protection and ground fault protection within the ATS, eliminating the need for separate upstream protective devices.
