The ETITEC M T12 950/12.5 4Y RC surge arrester is a highly efficient combined-type protection device (Type 1+2) designed for comprehensive protection of electrical networks against impulse surges, including those caused by lightning. By combining the functions of a Type 1 arrester (protection against direct lightning current) and a Type 2 arrester (protection against switching surges), it provides reliable protection for equipment in networks with a rated voltage of up to 950 V.
The model is equipped with four modules, ensuring multiphase protection and uniform load distribution among the phases. The presence of an RC contact (remote signaling contact) allows for remote monitoring of the device’s status, enhancing the safety and convenience of operating the protection system. The device housing has an IP20 protection rating and is yellow in color for easy identification among other components in the electrical panel. Installation is performed on a standard DIN rail, ensuring quick and reliable mounting.
