The load resistors cabinet ARM consists of a resistance box, a non-sealable terminal strip and a 2A circuit breaker, located in a metal cabinet with ventilation and connections protected by a sealable cover to prevent tampering.
Box load resistors, is comprised of three load resistors contained in a metal box with surface treatment to prevent corrosion and to evacuate the heat.
It is designed for indoor use. On request it can be manufactured for outdoor service and with different configurations.
Its function is to consume the necessary power for the transformer to work at least at 25% of the accuracy burden in cases where the loads connected to the unit (meters, relays,etc.) do not reach the minimum necessary to guaranteed measurement accuracy.
