Phoenix Contact knife disconnect terminal block
These knife disconnect terminal blocks feature a finger-actuation mechanism for test and measurement applications. The UT 4-MTL’s and UT 6-MTL’s finger levers enable technicians to safely perform circuit-polarity checks and troubleshooting without disrupting service. The 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 valuable in critical relay protection cabinets housed in substations, where instrumentation and control engineers sometimes test thousands of I/O terminations. The blocks accommodate colored knife disconnect levers to differentiate circuits, while conserving space and assisting wire management.
