This Thomson TS870-TCP Automatic Transfer Switch is ideal for transferring commercial & industrial three phase loads up to 800A. The TCP Connection Plate allows for quick camlock connections to a temporary generator.
TRANSFER SWITCH FEATURES
- Employs two mechanically interlocked power switching units with a micro- processor based controller.
- Automatically starts generator and transfers system load to generator supply in the event of a utility supply failure.
- Automatically re-transfers back to the utility supply following restoration of the utility power source to within normal operating limits.
- All load transfer sequences are “Open Transition” (i.e. “break-before-make”) with adjustable neutral position delay to ensure adequate voltage decay for preventing out of phase transfers.
- Solid Neutral standard on 4 wire systems. (Please inquire about other options.)
- Fully enclosed silver alloy contacts provide high withstand rating & 100% continuous current rating.
- 3 cycle short circuit current withstand tested.
- 10 cycle 6X overload current rating.
- Completely separate utility and generator side power switching units.
- Not damaged if manually switched while in service.
- Safe manual operation permits operation under adverse conditions.
- Heavy duty brushless gear-motor and operating mechanism provide mechanical interlocking and extreme long life.
- Superior serviceability with all mechanical and control devices visible and front-accessible, all control wires and power busses are front-accessible, and a plug-in TSC 7320 Transfer Controller.
- ISO 9001 registered for quality assurance.
- Seismic Certified for installation and operation per the following requirements: IBC 2012 – Section 13, Occupancy Category IV; ASCE7-05 Region 3 (minimum SS=200%).
- Certified to CSA 178 & UL 1008 Standards.
- NEMA 1 indoor standard. Optional NEMA 3R outdoor enclosure also available. (See Option below for other available enclosures.)
- Note: Molded case circuit breakers or fuses with overcurrent protection are required upstream of the transfer switch.
- Not Service Entrance Rated.
TCP CONNECTION PLATE FEATURES
- Enables your facility to quickly and safely receive backup power when utility power is interrupted.
- Ideal for temporary mobile or rental generator applications.
- Allows for quick camlock connections to the generator.
- Eliminates the need for a separate tap box.
- Factory installed.
- Certified with the transfer switch to UL 1008 supplemental SB.

CLOSED TRANSITION OPTION (Call for Pricing)
- Employs two electrically interlocked molded case (MCCB/MCS) power switching units and a microprocessor based controller to automatically allow a Closed Transition (make-before-break) load transfer when both utility and generator sources are available.
- All Closed Transition transfer sequences ensure both sources of power are in synchronism prior to transfer and load is transferred without power interruption.
- Automatic control & protection circuits ensure the generator and utility supplies are only in parallel for a maximum of 100 milliseconds to permit an uninterrupted load transfer.
- Reverts to an Open Transition load transfer sequence when only one power source is available.
- All voltage gap and frequency gap settings are adjustable.
- Closed Transition Mode can be bypassed to Open Transition Mode within the TSC 7320 Controller.
- An Auto/Manual Switch is provided for safe Manual operation in Open Transition mode with positive push button controls.
- Specifically designed and certified to UL 1008 Standards.
- Ideal for Emergency Power System applications such as commercial, industrial, or government institutions that require automatic standby power and minimal power interruptions to the load.
