Bimetallic Overload Relays

Benshaw RMSO/SPO Series Overload Relays are bimetallic-style relays designed to protect AC-3 circuits (up to 150A @ 690V) and motors against overloads, phase failure, long starting times and stalling of the motor. RMSO and SPO Series overload relays can be integrally mounted to Benshaw RC and RSC contactors for thermal overload protection.
