Product Description

MCCB Highlights

The molded case circuit breaker has overload, short circuit and undervoltage protection functions, and can protect lines and power equipment from damage.

According to the rated ultimate short-circuit breaking capacity, the mccbs are classified into four types: C (economic type), L (standard type), M (medium breaking type) and H (high breaking type).

ARM3 accessories are modularized, safe and reliable, with small volume, high breaking capacity, short flashover, high vibration resistance, etc.

The moulded case circuit breaker has passed the test requirements of GB/T2423 and IEC60947 standard, and can withstand the influence of humid air, salt mist, oil mist and mold.

The neutral pole type of ARXM3-125~630 mccb is A/B circuit breaker when it is of 4 poles specification, which can have a unique function of "overload alarm without tripping" to ensure the continuity of power supply and meet the requirements of Article 6.3.6 of GB50054.

It is required to withstand mechanical vibration with frequency of 2Hz~13.2Hz, displacement of ± 1mm, frequency of 13.2Hz~100Hz and acceleration of ± 0.7g.
