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.
The ARM TT+TI is a load resistor cabinet designed for a set of voltage and current transformers (VT & CT). It comprises a slotted enclosure containing 3 resistors (current circuit), a group of 3 resistors (voltage circuit), their respective terminal block, and a 2 A Miniature Circuit Breaker (MCB). These components are housed in a metal cabinet featuring ventilation (natural or forced, depending on the requested specifications), with connections protected by a sealable cover.
The cabinet is manufactured from sheet steel (lacquered or stainless, according to requirements) and features a 3 mm double-bit lock operated by a cam, sealed via a slotted screw to prevent unauthorized tampering.
It is designed for indoor service. Upon request, it can be manufactured for outdoor service, as well as in various other configurations.
Its function is to consume the necessary power to ensure the transformers operate at a minimum of 25% of their rated accuracy burden. This applies in cases where the loads connected to the device (meters, relays, etc.) do not reach the minimum threshold required to guarantee measurement accuracy.

It is designed for indoor service. Upon request, it can be manufactured for outdoor service, as well as in various other configurations.
Its function is to consume the necessary power to ensure the transformer operates between 25% and 100% of its rated accuracy burden. This applies in cases where the loads connected to the device (meters, relays, etc.) do not reach the minimum threshold required to guarantee measurement accuracy.
