KIT ATCONTROL/B PLUS - Complete kit including self-configurable permanent and transient overvoltage and undervoltage protector, shunt release and circuit breaker.

KIT ATCONTROL/B PLUS series protectors trip the connected shunt release (S1, S2) when they detect a permanent overvoltage. The shunt release causes the circuit breaker to trip, protecting the equipment installed downstream.

The warning system for permanent overvoltages consists of two luminous indicators: green (correct power supply) and red (overvoltage). It has a test button to check that installation has been executed correctly.

KIT ATCONTROL/B PLUS series protectors trip the connected shunt release (S1, S2) when they detect 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 standard UNE-EN 61643-11 and GUÍA-BT-23 from the REBT. Suitable for categories I, II, III and IV equipment according to standard ITCBT-23 from the REBT.

It has a thermodynamic control device that disconnects from the electrical network in case of deterioration, and also a warning system for transient overvoltages. When the warning is yellow, the protector is in good condition. If not, replace.

KIT ATCONTROL/B PLUS series protectors have been tested in official, independent laboratories obtaining their characteristics according to applicable standards.

KIT ATCONTROL/B PT-T 32 PLUS - Kit with three-phase protector against permanent and transient overvoltages and undervoltages, shunt release and MCB with nominal current 32A. Actuating time 275V→3-5s/ 400V→0,1-0,2s. 200V→3-5s/ 80V→0,1-0,2s. Imax=40kA.
