The molded case circuit breaker (MCCB) features overload, short circuit, and undervoltage protection functions to protect lines and power equipment from potential damage.
Based on their rated ultimate short-circuit breaking capacity, the MCCBs are classified into four distinct types: C (economic type), L (standard type), M (medium breaking type), and H (high breaking type).
ARM3 accessories are modularized, safe, and reliable. They are designed with a small volume, high breaking capacity, short flashover, and high vibration resistance.
These moulded case circuit breakers meet the testing requirements of GB/T2423 and IEC60947 standards, proving their capability to withstand humid air, salt mist, oil mist, and mold.
For the 4-pole specification, the neutral pole type of ARXM3-125~630 MCCB functions as an A/B circuit breaker. It features a unique "overload alarm without tripping" function to maintain power supply continuity and meet Article 6.3.6 of GB50054.
The circuit breaker is built to withstand mechanical vibration with a frequency of 2Hz~13.2Hz (displacement of ±1mm), and a frequency of 13.2Hz~100Hz (acceleration of ±0.7g).
