DATASHEET
PRODUCT DESCRIPTION
IGA TEST T 25 - Three-phase protector against permanent, overvoltages, with integrated MCB, nominal current 25A. Actuating time 275V→8-10s / 400V→0,1-0,2s.
IGA TEST 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.
The protector is formed by protective coils for permanent overvoltage linked to a miniature circuit breaker (MCB).

INSTRUCTIONS
INSTALLATION
They must be installed in series with the low voltage line, with the input at the top of the protector.
The protective coils must be installed between the lines and the neutral at the bottom of the protector.
SAFETY AND MAINTENANCE
Installation should be carried out without power in the line and can only be done by authorized professionals.
