MSB6 surge protectors Type 3 are designed for effective protection of sensitive equipment, in addition to the surge protector installation (coordination surge protector). These surge protectors utilize a ultra compact and economica scheme based varistors, to obtain a power flow relevant for secondary protection. The operating condition of the arrester is signaled by buzzer.
