MB1 series miniature circuit breakersDetailed product description：

MB1 series miniature circuit breakers are suitable for working environments and installation conditions
1. Environmental temperature: -35 ℃~+70 ℃;
2. Altitude: The altitude of the installation location of the contactor shall not exceed 2000m;
3. Relative humidity of the air: ≤ 95%;
4. Environment with pollution level 2;
5. Places without significant vibration and impact.

structural characteristics
The MB1 series miniature circuit breaker consists of a plastic casing, an operating mechanism, a contact arc extinguishing system, and a trip mechanism. The shell is made of high flame retardant and high-strength special plastic, with strong impact resistance and light weight. The components of the circuit breaker operating mechanism are made of high-strength plastic materials, which ensure sensitivity and reliability while obtaining the lowest moment of inertia, making the time from the start of a short circuit fault to the action of the trip mechanism very short. The trip mechanism consists of two parts: a bimetallic overload inverse time trip mechanism and a short-circuit instantaneous electromagnetic mechanism.
TH35mm standard installation rail installation - easy and convenient to install.

Scope of application
The MB1 series miniature circuit breaker is mainly suitable for circuits with AC 50/60Hz, rated working voltage of 230V/400V and below, and rated current up to 100A. It is mainly used for overload and short circuit protection of electrical lines and equipment.
