Product Description

The Phoenix Contact 1004366 (UT 4-MTD) is a space-saving double-level knife disconnect terminal block from the UT series, combining two independent disconnect circuits in one compact 6.2 mm wide unit. Each level features a lever-actuated knife disconnect for safe isolation, ideal for current transformer secondary circuits, multi-level testing points, and dense control wiring where frequent measurements are needed. It allows insertion of test plugs or bridges on both levels without interrupting wiring, making it perfect for complex automation panels and switchgear.

Standard Features

  • Knife Disconnect Function: Integrated knife disconnect allows safe and clear electrical isolation for testing and maintenance

  • Compact DIN-Rail Design: Slim 5.2 mm housing enables high-density wiring on standard NS 35 DIN rails

  • Spring-Cage Connection: Maintenance-free spring clamp technology ensures vibration-resistant and reliable conductor connection

  • Wide Conductor Compatibility: Supports solid, stranded, and ferruled conductors from 0.08 mm² to 4 mm² (AWG 28–12)

  • Clear Circuit Identification: Blue housing color enables easy visual differentiation of neutral or signal circuits

  • High Electrical Performance: Rated up to 400 V AC and 20 A for standard industrial control circuits

  • Tool-Assisted Operation: Knife disconnect can be safely actuated using standard insulated tools

  • Industrial Panel Application: Designed for control cabinets, signal isolation, and measurement loops in automation systems
