Product Description
Benshaw SPO-40-3A3 Bimetallic Class 10 3 pole overload with a range from 2.5 to 4 AMPS and mounts directly to the RSC-32 and RSC-40 contactors in any coil voltage. This 3 phase thermal overload relay comes with an adjustable dial for easily setting the range to match the Full Load AMPS (FLA) of the motor that needs protection. The Benshaw SPO-40-3A3 has an option for manual or automatic reset along with a test button and visual indicator of a tripped state. A pair of auxiliary contacts, 1 normally open and 1 normally closed come with this overload relay for signalling purposes and to cut power to the coil and shut the starter down, thus preventing any damage to the motor.
