Phoenix Contact UT 4-L Terminal Blocks are multi-level fuse terminal blocks ideal for process engineering applications, such as oil and gas and petrochemical. UT 4-L series provides an all-in-one solution for DCS marshaling with certification for use in Non-Incendive Electrical Equipment for Class I, Zone 2 and Class I, Division 2 Hazardous Locations. The new multi-level terminal block with fuse, feed-through level, and grounding foot offers high functionality in a 6.2mm pitch. The 6.2mm pitch reduces the required DIN rail space by 66% compared to single-level options that require multiple blocks to accomplish the same function. The series is designed for protecting and isolating sensors and other I/O.
