Description

marker

The MBM1 plastic body circuit breaker (commonly called "air circuit breaker") is a high-performance low-voltage protective device widely used in power distribution systems and 50/60Hz AC motor protection circuits with rated voltages up to 400V, performing the key functions of line overload, short-circuit and overcurrent protection.

The product adopts the principle of thermal and magnetic release, combining a bimetallic thermal release and an instantaneous electromagnetic release. The thermal release provides overload protection with an inverse time dependence, and in the event of a short circuit, the electromagnetic release provides instantaneous operation (capacity up to several tens of kA), effectively limiting the fault current and protecting electrical appliances and lines. The body is made of high-strength, fire-resistant engineering plastic, the design is compact, and the weight is light.

The MBM1 series offers varying levels of current and capacity ratings, and features clear on/off indicators and reliable contact position indication. With high capacity, precise protection characteristics, reliable operation and ease of installation and maintenance, these devices have become indispensable key protection elements in low-voltage power distribution systems in construction, industrial control and power infrastructure.
