Hager MZ204 Shunt Trip Release 12-24V DC / 24-48V AC

The Hager MZ204 shunt trip release is a specialized modular accessory engineered for the remote control and disconnection of circuit breakers. By integrating this device into your electrical distribution system, you gain the ability to trigger a breaker trip via an external signal, ensuring rapid response during critical situations. It is designed to operate seamlessly within a voltage range of 12-24V DC or 24-48V AC, providing versatility for various low-voltage control applications.

Advantages

This shunt trip release offers a robust solution for enhancing safety in electrical installations by enabling automated or manual remote disconnection. Its modular design ensures compatibility with standard Hager circuit breakers, facilitating a straightforward installation process without requiring extensive modifications to the existing panel layout. The device is built to high manufacturing standards, ensuring consistent performance and reliability when integrated into complex electrical protection schemes.

Suitable for

• Emergency shutdown systems in industrial or commercial buildings
• Remote circuit breaker management in control panels
• Integration with fire alarm or safety monitoring systems
• Automated electrical load shedding applications

This device may not be suitable for high-voltage applications outside the specified 12-24V DC or 24-48V AC range. It is also not intended for use as a primary protection device against overcurrent or short circuits, as it functions strictly as an auxiliary tripping mechanism.

Key specifications

• Operating voltage: 12-24V DC / 24-48V AC
• Compatibility: Modular Hager circuit breakers
• Function: Remote shunt trip release
• Mounting: DIN rail modular system

To use the Hager MZ204, mount the device onto the DIN rail adjacent to the compatible circuit breaker. Ensure that the mechanical coupling is securely engaged between the shunt trip and the breaker mechanism. Connect the control signal wiring to the designated terminals, adhering strictly to the specified voltage requirements. Once installed, verify the connection by applying a test signal to ensure the breaker trips correctly before putting the system into full operation.

What to consider before purchase

• Verify that your existing circuit breaker model is compatible with the MZ204 accessory
• Ensure your control signal power supply matches the 12-24V DC or 24-48V AC requirements
• Confirm that there is sufficient space on the DIN rail within your distribution board

Usage recommendations: Installation should only be performed by a qualified electrician in accordance with local electrical codes. Regularly test the remote tripping function during scheduled maintenance to ensure the system remains responsive and reliable.
