193-EF2 also includes:


Bulletin 193-EF overload relays offer precise and reliable ambient compensated overload protection for the protection of three-phase squirrel cage motors. DIP switch settings allow the Bulletin 193-EF overload relays to be closely matched to the motor characteristics to safely obtain full utilization of the motor. The wide adjustment range of the trip class setting allows the Bulletin 193-EF overload relays to be applied in a wide variety of applications. The 193-EF2 version offers enhanced motor protection with additional circuitry for monitoring motor winding embedded thermistors.
