Moulded Case Circuit Breaker (Thermal Magnetic )

Application of Moulded Case Circuit Breaker (Thermal Magnetic )
Our moulded case circuit breaker is a new circuit breaker developed on the basis of Mitsubishi PSS series. It complies with IEC C60947-2 and GB14048.2 standards.
With a rated insulation voltage of 690V, this moulded case circuit breaker is widely used to distribute electric energy and to protect the electrical circuit and power equipment from damages caused by overload, short circuit or under-voltage in the distribution network. It has a rated AC of 50 or 60HZ, rated working voltage 690V, and rated working current 800A. It can also be used to protect the electrical motor in the occurrence of an overload, short circuit, and under voltage. With a small volume, good breaking effect and short electric arcing, our moulded case circuit breaker is an ideal circuit breaker for your use.

Features of Moulded Case Circuit Breaker (Thermal Magnetic )
1. Classification: based on its rated short-circuit breaking capacity, it can be divided into three types, which have the same overall dimension in the same frame current:
---Compact type (C);
---Standard type (S);
---High capability type (H)
2. In order to make operation easier for users, the external dimensions of MCCB, ELCB, Thermal Magnetic Adjustable breaker and Electronic Adjustable breaker are uniformly divided into five kinds of sizes(adjustable breaker are divided into 4 kinds of sizes),under same frame size, the external dimensions of MCCB,ELCB, Thermal Magnetic Adjustable breaker and Electronic Adjustable breaker are completely same.
3. The panel dimension is of a standard and suitable design, with the rated current of 30A-800A;
4. This moulded case circuit breaker is easy to install and safe to operate. It has a case structure.
5. Standards: IEC60947-2, GB14048.2

Working Conditions and Mounting Environments
1. The altitude should be less than 2000m.
2. The ambient medium temperature should be within -5℃ to +40℃ (+45℃ for shipping product).
3. This moulded case circuit breaker is resistant to moisture, salt fog, oil fog, nuclear radiation, and mildew.
4. The maximum tilt angle is 22.5°.
5. It can still work reliably if the product is subjected to vibration from ships or earthquakes (4g).
