Overvoltage trigger for MCB, RCCB, RCBO 230VAC MZ212

Safety and electrical installation protection

The MZ212 surge arrester is an element designed to work with overcurrent circuit breakers (MCB), residual current devices (RCCB), and combined residual current and overcurrent devices (RCBO) with a voltage of 230VAC. Its task is to provide additional protection against the effects of overvoltages, which can damage connected devices or cause a fire. Installing this type of arrester is an investment in the long-term safety of the entire installation.

Construction and mounting

The arrester is characterized by its compact dimensions - its depth is 68 mm, height 87 mm, and width 17.5 mm. The electrical connection is made using screw connections, which ensures a secure and durable connection of the wires. The arrester is powered by alternating current (AC). The compact size facilitates installation even in crowded distribution boards.

Application and benefits

• Overvoltage protection: Protects the circuit from sudden voltage surges that can be caused, for example, by a lightning strike or a power grid failure.
• Compatibility: Designed to work with popular MCB, RCCB and RCBO circuit breakers with a voltage of 230VAC - universal application.
• Easy installation: Screw connections simplify and speed up the installation process, which is important for professional installers.
• Small size: The compact design allows installation in a limited space of the distribution board.
• Increased reliability: An additional layer of protection translates into a longer lifespan of connected devices and the entire electrical installation.
