New ATCONTROL/B P(T)-T (220V): overvoltage protection for 220V three-phase power supply lines

Combined three-phase protector against permanent and transient overvoltages, actuating on any shunt release.

New Aplicaciones Tecnológicas combined kits, designed for surge protection of structures with 220V power supply lines

PERMANENT OVERVOLTAGES

ATCONTROL/B P(T)-T protector activates whenever it detects a permanent overvoltage,  triggering its own shunt release  (S1, S2). That shunt release causes the disconnection of the associated Main Circuit Breaker (MCB), thus protecting the equipment installed downstream.

The warning system for permanent overvoltages consists of  two LEDs: green for correct power supply and red  indicating overvoltage. It is also provided with a test button to check that the installations have been executed correctly.

TRANSIENT OVERVOLTAGES

ATCONTROL/B PT-T protector also acts whenever it detects a transient overvoltage, driving the current to earth and reducing the voltage to a level that does not damage the connected equipment.

Tested and certified as Type 2 protector in official and independent laboratories, according to the standard IEC 61643-11.

It is provided with a thermodynamic control device that disconnects from the electrical network in case of degradation, as well as a warning system indicating if the protector should be replaced.
