IGA TEST SUB M: new transient and permanent overvoltage prewired protector


At Aplicaciones Tecnológicas we have launched a new combined surge protector, the IGA TEST SUB M.

IGA TEST SUB M: new transient and permanent overvoltage prewired protector    

This device acts against both transient and permanent overvoltages and is pre-wired, with an integrated miniature circuit breaker. With a 4DIN compact size, it is especially suitable for installation in a reduced space of a distribution panel.

Due to its configuration as a two-in-one device, with the IGA TEST SUB M it is not necessary to replace the whole device at the end of its life, as it allows for a single replacement of either the transient surge protector or the circuit breaker against permanent overvoltages. This greatly reduces maintenance costs.

The protector has been tested and certified in official and independent laboratories according to standards UNE-EN 61643-11 and GUÍA-BT-23 from the REBT.
