The TS 870 bypass isolation switch provides the same reliable features that are available in the TS 870 automatic transfer switch.The TS 870 bypass isolation switch incorporates two basic types for bypass-isolation. Type "B" (double-sided ) isolates the transfer switch and can bypass either the utility or generator source of the load, as selected by the operator. Single-sided bypass types "D" (utility bypass) and "C" (generator bypass) can bypass only one source to the load (in accordance with CSA 282-00 - Institutional & Residential Buildings Occupancy Group Band C). Note: CSA 282-00 requires (as a minimum) a single sided bypass on the generator supply. The TS 870 series mechanisms utilize enclosed contact power switching units which provide a 100% continuous rating. The switches are mounted independently on a common frame.

Features and Benefits of the TS 870 Series Bypass / Isolation:

Enclosed Contact Power Switching Units fully enclosed silver alloy contacts provide high withstand rating & 100% continuous current rating.
Barriers between the transfer switch and bypass isolation switch reduce the chance of consequential damage if there is a failure in either the transfer switch or bypass isolation switch.
When isolated there is no power in the transfer switch compartment providing true isolation.
Not damaged if manually switched while in service since contacts have inherent spring over center design.
Reliable Motor-Operated Transfer Mechanism heavy duty brushless gearmotor and operating mechanism provide mechanical interlocking and extreme long life with minimal maintenance.
Safe manual operation with permanently affixed handle, permits easy operation under adverse conditions.
All control wires and power busses are front-accessible, eliminating the cost and complexity of a drawout transfer switch.
Control Features TSC 80 microprocessor based controller.
Isolation plug permits disconnecting control circuits from all power sources for safety and convenience.
Control circuitry permits complete off load testing of the transfer switch when isolated (a drawout transfer switch is not required).
Isolation Switch allows bypass with load interruptioon (double sided bypass only).
