Release Trigger Module Noark 101399 for EX9M1 Circuit Breaker 220–240 V AC SHT21

Noark release trigger module 101399 is designed to function as a trip/shunt release (SHT21) for EX9M1 series circuit breakers. The module operates on 220–240 V AC and enables remote or electrical tripping of the circuit breaker when integrated into an electrical distribution panel. It is intended for applications that require controlled disconnection of power circuits, adding a means of remote actuation for protection and maintenance tasks.

Advantages

The release trigger module provides reliable electrical actuation of EX9M1 breakers using standard 220–240 V AC supply, enabling remote tripping without mechanical intervention. Its design allows straightforward integration into distribution boards and protection schemes, preserving the breaker’s core overcurrent and short-circuit protection while adding remote control capability. The module contributes to improved operational flexibility in systems where rapid electrical disconnection is required.

Suitable for

• Remote tripping of EX9M1 circuit breakers in distribution panels
• Electrical protection schemes requiring an external trip or shunt release
• Maintenance procedures where breakers must be disconnected electrically
• Industrial, commercial, and residential installations using EX9M1 breakers

Key specifications

• Function: Trip / Shunt release (SHT21) for EX9M1 breakers
• Operating voltage: 220–240 V AC
• Integration: Mounts to and interfaces with EX9M1 breaker mechanisms
• Application area: Electrical distribution panels and protection circuits

How to use

Install the release trigger module onto a compatible EX9M1 circuit breaker according to the breaker manufacturer’s installation instructions and wiring diagrams. Connect the 220–240 V AC control supply and any remote control wiring following applicable electrical standards and safety practices. After installation, verify correct electrical connections and perform functional tests to confirm the breaker trips when the release module is activated. Ensure power is isolated before performing installation or maintenance.

Usage recommendations

Use the module only with EX9M1 series breakers and the specified AC supply voltage. Follow local regulations and the breaker manufacturer’s guidance for wiring, mounting, and testing. Regularly inspect electrical connections and test the trip function as part of preventive maintenance to ensure reliable operation.
