Description
Micro Circuit Breaker up to 125A is a low voltage miniature circuit breaker (MCB). It is a 1P circuit breaker with 1 protected pole, 1A rated current and B tripping curve. The rated short circuit breaking capacity goes up to 50kA at 220VAC to 240VAC conforming to EN/IEC 60947-2 standard and 6000A at 230VAC conforming to EN/IEC 60898-1 standard. It complies with both industrial standard EN/IEC 60898-1 and residential standard EN/IEC 60947-2. This miniature circuit breaker protects circuits against short circuit and overload current. Its fast closing mechanism independent of manual operation improves its service life. It has an electrical endurance going up to 10000 cycles and a mechanical endurance going up to 20000 cycles. The Ui rated insulation voltage is 500VAC. Its limitation class 3 (according to EN/IEC60898-1) improves downstream circuit protection cost. The product can be clipped on a DIN rail. Its width is 2 pitches of 9mm. Pollution degree is 3. Overvoltage category is IV. The product colour is white. The weight is 0.215kg. According to IEC 60529 standard, the degree of protection is IP20 and IP40 in enclosure. The operating temperature is -35°C to 70°C. The storage temperature is -40°C to 85°C.
ApplicationsMicro Circuit Breaker up to 125A are widely used in residential and commercial buildings as primary protective devices in low-voltage electrical installations. They are also utilized in industrial applications for protecting equipment like motors and pumps, as well as in automotive applications for safeguarding various components.
