Description

The DSPD-AC275-50 4P surge arrester class T1+T2 (B+C) provides complete protection of the electrical installation and the electrical devices supplied from it against the effects of lightning current and all types of surges. They limit overvoltages and conduct to ground surge currents originating from both types of overvoltages – direct and indirect. They also provide a two-stage level of protection. Their use does not require the use of decoupling chokes. The BC surge protector provides effective protection for computers, consumer electronics, household appliances and more. The BC protector model has a modular structure and activation signaling on the front of the device, meeting the requirements of protection classes I and II.
