New ATCONTROL KIT series: protective devices against permanent and transient overvoltages

Aplicaciones Tecnológicas’s combined surge protectors are especially suitable for protecting common areas of residential buildings.

Aplicaciones Tecnológicas launches new combined protective devices against permanent and transient overvoltages for 6, 10, 16 and 20A nominal current. Due to their characteristics, these new protectors are particularly suitable for protecting common areas of residential buildings or complexes.


ATCONTROL/B series protector actuate triggering the contact shunt release (S1, S2) whenever it detects a permanent overvoltage. The shunt release causes the disconnection of the Main Circuit Breaker (MCB) associated, protecting the equipments installed downstream. The warning system for permanent overvoltages consists in 2 luminous indicators: green (correct power supply) and red (overvoltage). It has a test button to check that the installations have been executed correctly.


ATCONTROL/B protector works as well 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.

Certified according to the specifications described in the European standard EN 50550 – Power frequency overvoltage protective device for household and similar applications (POP), our ATCONTROL KITS have been tested by ÍTACA, official and independent Laboratory of Electrical Safety.

New ATCONTROL KITS protectors for low current are available for both single and three phase systems. For more technical information, download our KIT ATCONTROL product sheets here:
