The ARXM3 series molded case circuit breakers (MCCB) are designed for superior electrical protection in industrial applications. These circuit breakers feature reinforced construction with high-quality materials to ensure reliable operation under demanding conditions.
Available in thermal magnetic, electronic and leakage protection types, the ARXM3 series offers comprehensive protection against overloads, short circuits and undervoltage conditions. The breakers are classified into four types based on their rated ultimate short-circuit breaking capacity: C (economic), L (standard), M (medium breaking) and H (high breaking).
The circuit breakers feature several material advantages including heat shrinkable insulating materials, high silver content alloy contacts (up to 95% silver), and high-strength mechanism components. These premium materials contribute to extended electrical life, improved breaking capacity, and enhanced durability.
Key features include modular accessories for easy installation, compact design, high vibration resistance, and compliance with GB/T2423.10 and GB/T2423.18 standards for environmental durability. The 4-pole versions offer unique 'overload alarm without tripping' functionality to maintain power continuity.
The ARXM3 series is suitable for various industrial applications requiring reliable circuit protection. The humanized design allows for easy accessory installation and maintenance, while the premium materials ensure consistent performance in challenging environments.
