• Automated emergency shutdown circuits
• Remote control of circuit breakers

When it may not be suitable

This device is not intended for use with incompatible circuit breaker models or systems operating outside the specified voltage range of 110-415V AC/DC. It should not be installed in environments where the electrical load or environmental conditions exceed the manufacturer's rated specifications for this component.

Key specifications

• Operating voltage: 110-415V AC/DC
• Function: Remote shunt trip release
• Compatibility: Designed for Siemens circuit breakers
• Application: Electrical circuit protection

How to use

The installation of the shunt trip release must be performed by a qualified electrician in accordance with local electrical codes. The device is typically mounted onto the side of the compatible circuit breaker. Once mechanically secured, the control wiring is connected to the terminals, allowing an external signal to trigger the release mechanism. Ensure all power is disconnected from the main circuit before attempting installation or wiring.

What to consider before purchase

• Verify compatibility with your existing circuit breaker model
• Ensure the control voltage matches your system requirements
• Confirm that installation space is available within the distribution board

Usage recommendations

Always test the remote tripping functionality after installation to ensure the circuit breaker responds correctly to the control signal. Regular maintenance checks are advised to confirm the integrity of the electrical connections and the mechanical operation of the release.
