 | 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.
