3P Molded Case Circuit Breaker - Reliable China Manufacturer & Supplier

As a professional MCCB manufacturer and supplier in China, SPX Electric factory would like to provide you high quality 3P molded case circuit breaker, which has three circuit disconnection switches and can protect circuits of three phases.

Product functions

1. Distribute electrical energy

3P Molded case circuit breaker is one of the main functions of distribution of electrical energy. In power systems, molded case circuit breakers can distribute electrical energy from the power source to different loads, ensuring that each load receives a stable power supply.Through the reasonable selection and configuration of the molded case circuit breaker, the rational distribution and effective use of electric energy can be realized, and the operation efficiency and stability of the whole power system can be improved.

Molded case circuit breakers feature high reliability, high safety and multiple protection functions (such as overload protection, short-circuit protection, etc.), which can ensure that the circuit is cut off in time when the load is abnormal, preventing damage to electrical equipment and the occurrence of electrical fires.

2. Isolation voltage

Customized 3P Molded case circuit breakers also have the function of isolating voltage. When it is necessary to inspect, maintain or replace electrical equipment, by operating a molded case circuit breaker, the electrical equipment can be isolated from the power supply to ensure the safety of maintenance personnel. When in the open state, the molded case circuit breaker can isolate the voltage between the power supply and the load, reducing the risk of electric shock and protecting the lives of maintenance personnel.In addition, the molded case circuit breaker also has a reliable locking mechanism to ensure that the circuit breaker will not be misoperated during maintenance, further improving safety

All three poles are equipped with trip units to control the three-phase live wires (L1/L2/L3), making it suitable for three-phase balanced loads (such as motors)

If you are not quite sure about the model you need, you can send us an email about the current, voltage and other details of the relevant usage scenarios. Our professional technicians will answer your questions.
