Modular arresters VCX-L2-BC class T1 T2 They are dedicated to protecting LV power supply installations against the effects of induced and switching overvoltages. They should be used as both the first and second level of protection in floor boards and sub-distribution boards. The arresters should be installed at the points where the electrical installation enters the building. They provide complete protection of the electrical installation and the electrical devices powered by it against the effects of part of the lightning current and other types of overvoltages. They reduce overvoltages and reduce surge currents from both types of overvoltages - direct and indirect - to the ground. They also provide a two-stage level of protection. The use of modular surge arresters VCX-B+C class T1T2 does not require the use of decoupling chokes. They provide effective protection for computers, electronics/home appliances, etc. They are equipped with a visual operation indicator (green - protection, red - no protection).

It has integrated thermal protection - it does not require additional thermal protection (although it is always recommended).
