The ARXM3 series molded case circuit breakers are designed for reliable circuit protection in industrial applications. This 125A 3Pole MCCB features thermal magnetic trip units with four breaking capacity levels (C/L/M/H) to meet different protection requirements.
Key features include reinforced BMC base construction, modular accessories design, and compliance with GB/T2423.10/18 standards for environmental resistance. The circuit breaker provides overload, short circuit and undervoltage protection functions to safeguard electrical systems.
Material advantages include: heat shrinkable insulating materials (VO flame retardant nylon PA66), high silver content alloy contacts (95% silver), QPQ salt bath treated mechanism components, and high sensitivity temperature sensors. These premium materials ensure longer electrical life and superior performance.
The ARXM3-125 model offers multiple current ratings from 16A to 125A with AC400V/35KA (C type) to AC400V/100KA (H type) breaking capacities. The compact design (75-122mm width) makes it suitable for space-constrained installations.
