Phoenix Contact’s (Middleton, PA) newest knife disconnect terminal blocks feature a quick and safe finger-actuation mechanism for test and measurement applications. The UT 4-MTL and UT 6-MTL’s finger levers enable technicians to safely perform circuit-polarity checks and troubleshooting without disrupting service. The MTL lever does not require a tool to actuate. It extends above and beyond the recessed version found in standard UT 4-MT and UT 6-MT disconnects. This is especially valuable in critical relay protection cabinets housed in substations, where instrumentation and control engineers sometimes need to test thousands of I/O terminations.
