IGA TEST - Protector against permanent overvoltages with integrated miniature circuit breaker.

IGA TEST series protectors cut off the power supply when they detect a permanent overvoltage (for example, a fault in the neutral), thus protecting the equipment installed downstream. 

IGA TEST protectors against permanent overvoltages can be installed together with ATSUB-D transient overvoltage protectors. 

The integrated MCB is available for the most usual nominal currents: 25, 32, 40, 50 and 63 A.

IGA TEST series protectors have been tested in official, independent laboratories obtaining their characteristics according to applicable standards.

IGA TEST M 20 - Single-phase protector against permanent overvoltages, with integrated MCB, nominal current 20A. Actuating time 275V -> 8-10s / 400V -> 0,1-0,2s
