Product Description
Benshaw Surprotex SPE-40 Electronic Overload relay with selectable trip class from 5-30, AMP ranges from 8 to 40 AMPS (must choose specific AMP range above), screw terminals and an option for direct mount or separate mount. Direct mount overload only mounts to RSC-32 and RSC-40 contactors. Separate mount overload relay has option for DIN rail mounting or screw mounting to panel board.
The Benshaw SPE-40 series of overloads has solid state (electronic) protection which offers an increase in possible AMP ranges (over traditional thermal overloads) in addition to multiple class selection (from 5 seconds to 30 seconds). And since the majority of the SPO-40 thermal overloads are obsolete and no longer available from Benshaw, using this overload relay can save the cost and time of replacing the contactor, which would be the case if you have to use the RMSO32 series overloads.
