SPO Series Class 20 Overload Relay (260 – 400A – Direct Mount to RSC-300 and RSC-400 Contactors)
Benshaw RMSO/SPO Series Overload Relays are bimetallic-style relays designed to protect AC-3 circuits 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.
Benshaw Overload Relays are guaranteed for two full years. Other manufacturers limit their warranties to just one year. But at Benshaw, we believe that, because we build them better, we can guarantee them longer. We call that The Benshaw Promise.
