The ARXM3 series circuit breaker utilizes thermosetting insulating materials formulated with a unique recipe that delivers high strength, exceptional arc resistance, robust insulation, high-temperature tolerance, and outstanding flame retardancy.
No. Thanks to the highly sensitive fixed temperature sensor made from premium bimetallic materials, there is no need to reduce the operating capacity (current) within a temperature range of -5℃ to 55℃.
The spring materials used in the ARXM3 series are engineered for advanced temperature and fatigue resistance, providing a service lifespan that is 50% longer than standard electrical switch springs.
The ARXM3 series circuit breaker is designed to support front panel wiring, rear panel wiring, and plug-in rear panel wiring configurations to accommodate different installation demands.
For the 400V rated working voltage (Ue), the rated service short-circuit breaking capacity (Ics) reaches 50kA (level L), 75kA (level M), and 75kA (level H), respectively, according to the configuration.
