The Cutler-Hammer SPHM2RM0020 is a hydraulic-magnetic two-pole circuit breaker designed to protect electrical circuits from overcurrent by quickly interrupting both conductors when a fault is detected. With a 20A rating, it trips to isolate the affected circuit and safeguard wiring and connected equipment. Leveraging hydraulic-magnetic technology, it combines a magnetic trip for fast short-circuit response with a fluid-filled mechanism that helps prevent nuisance trips during normal startup or transient surges. This 2-pole device is suitable for use in electrical panels or equipment assemblies where simultaneous interruption of two lines is required.
