The 4P 40A 30mA rail relay is a key component of electrical installation safety systems, providing effective protection against electric shocks and minimizing the risk of fires arising from short circuits. The device features four poles, making it an ideal solution for three-phase installations. With a rated current of 40A and a sensitivity of 30mA, the switch responds quickly to any anomalies in the electrical circuit, automatically cutting off the power supply.

Thanks to the use of high-quality materials, the product ensures long-lasting and reliable operation. Its compact dimensions and innovative design allow for easy installation in standard distribution panels. It is recommended for use in both residential and industrial settings where the safety of users and electrical devices is a priority.
