Overview

The General Shunt Trip Unit is a reliable accessory for DLM1, DLM1E, and DLM1LE Series Molded Case Circuit Breakers (MCCBs). It provides remote tripping control through an external voltage signal, allowing the circuit breaker to trip instantly for emergency shutdown, fault protection, and remote power management.

This unit is available in two connection types to suit different installation needs:

  • With Lead Wires: flexible wiring design, convenient for connection in compact or complex control cabinets.

  • With Terminal Connection: stable and firm connection, ideal for fixed installations and industrial applications.

When the control voltage (AC or DC) is applied to the shunt trip coil, the mechanism is activated and immediately opens the circuit breaker, achieving fast circuit isolation. This enhances system safety, supports automated control, and ensures reliable protection for equipment and personnel.

Key Features:

  • Compatible with DLM1 / DLM1E / DLM1LE Series MCCBs.

  • Available in Lead Wire Type and Terminal Type for flexible installation.

  • Enables remote tripping via AC or DC control signal.

  • Ideal for emergency shutdown, remote fault isolation, and safety interlock systems.

  • Compact structure, easy mounting and maintenance.

  • Ensures reliable performance and long service life.

The General Shunt Trip Unit is the perfect choice for industrial control panels, building management systems (BMS), and smart power distribution where remote safety control is required.
