Reversing starters (9 A through 180 A) incorporate a “dual” interlock that provides both mechanical and electrical interlocking in a single unit. A normally open auxiliary contact is also included on each contactor. Conformity to Standards: CSA 22.2 UL 508 Your order must include: • Cat. No. of the reversing starter selected. • Coil Voltage Code. • Overload Relay Suffix Code. 3-64 Bulletin 105 IEC Reversing Starters Product Selection Open Type — Eutectic Alloy Overload Relay — AC Operated Reversing Starters with AC Coils — Starters require 3 overload heater elements.
