Type 2 surge arrester Vigivolt V3T-15

for transient current protectionvaristorgas discharge tube

Transient surge protection device, caused by atmospheric discharges, switching maneuvers in electrical circuits and electrostatic discharge. The device incorporates protection with GAS discharger to avoid possible current leakage to ground due to varistor wearing out. It avoids the damages that these transient surges can cause to the equipment powered from this supply. This device DOES NOT PROTECT AGAINST PERMANENT OVERVOLTAGE. Nominal voltage (Un): 230 VAC (L/N) Maximum voltage (Uc): 320 VAC (L/N) Frequency: 50-60 Hz Maximum discharge current 8/20µs L/N (Imax): 15kA Nominal discharge current 8/20µs L/N (In): 8kA Maximum discharge current 8/20µs N/PE (Imax): 15kA Nominal discharge current 8/20µs N/PE (In): 10kA Protection level L/N (Up): <1.5 kV Protection level N/PE (Up): <1.5 kV Overvoltage response time: ≤25 ns Previous protection fuse: 63A gL Maximum cable section in terminals: 16 mm² Temperature range: -40º…+80º C
