Intrinsically Safe Surge Protection

Surge protection – barriers to protect electrical low voltage equipment due to surge overvoltage generated in the management indirect effect, lightning or  before overvoltage,which occurs on running his own iduction. Surge barrier type PB protects electronic circuits against overvoltage over 28V. Given that the barriers are passive quadripole and their costruction meets the requirements for explosion-proof equipment is possible with their help protect and intrinsically safe equipment to level II 1G [ia]  IIC. Barrier itself may also be installed in potentially explosive atmospheres "Zone 2" or "Zone 1 and Zone 0" if it is a barrier free of elements accumulating energy. Surge barrier type PB.. according to design is placed in a plastic box and encapsulated in sealing compound (IP 20) or is placed in a box with IP 54 (IP 65) for outdoor use.
