Product Description
Benshaw SPO-150 Bimetallic Class 10 3 pole overload with ranges from 45A-150A (Choose specific range below) and mounts directly to the RSC-150 contactors in any coil voltage. These 3 phase thermal overload relays come 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-150 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.
