noark Release Device 101418 DO EX9M2(3) 220–240V — Auxiliary Release for Circuit Breakers

The noark Release Device 101418 DO EX9M2(3) 220–240V is an auxiliary trip module that enables electrical triggering of compatible circuit breakers. Designed for installation in industrial control panels, distribution boards and motor protection systems, this device accepts a 220–240 V supply to operate the breaker’s release mechanism remotely or automatically. It is intended to integrate with control circuits to provide reliable remote disconnection where manual intervention is impractical or where coordination with PLCs and protection relays is required.

Advantages

This auxiliary release offers straightforward electrical operation at standard mains control voltage, allowing easy integration into existing control systems. The compact design supports mounting adjacent to the breaker without significant panel space impact. Built to match the mechanical interface of compatible breakers, it ensures consistent actuation and repeatable tripping performance when a remote or automatic command is issued.

Suitable for

• Industrial control panels requiring remote breaker tripping
• Motor protection circuits where automatic disconnection is needed
• Distribution boards integrated with control and safety systems
• Automation systems using PLCs or external protection relays

Key specifications

• Operating control voltage: 220–240 V AC
• Function: auxiliary electrical trip / release for circuit breakers
• Compatibility: designed for use with matching noark circuit breaker models (mechanical interface type)
• Intended mounting: directly on or adjacent to the breaker within an electrical panel
• Operation mode: remote or automatic electrical actuation of the breaker release mechanism

How to use

Install the auxiliary release onto the compatible circuit breaker following the breaker manufacturer's mechanical attachment instructions and panel wiring standards. Connect the 220–240 V control supply to the device’s designated control terminals, observing correct polarity and protective fusing as required by local electrical codes. When the control voltage is applied, the module actuates the breaker’s release mechanism to open the circuit. Verify correct operation after installation using the breaker’s test procedure and by confirming correct interaction with the control system that will issue trip commands.

Usage recommendations

Use this module only with circuit breakers and panel configurations that are specified as compatible by the breaker manufacturer. Ensure control wiring is protected and routed to prevent accidental energization, and include appropriate overcurrent and fault protection in the control circuit. Perform commissioning tests and periodic functional checks to confirm reliable remote tripping performance.
