MOLDED CASE CIRCUIT BREAKER 3P

A molded case circuit breaker (MCCB) with 3P refers to a specific type of three-pole MCCB used in electrical distribution systems to protect circuits and equipment from overcurrents and electrical faults. Here is a description of its features and functioning:

1. Construction: The MCCB with 3P is housed in a durable molded case made of insulating materials such as plastic or thermoset. The case provides physical protection and insulation for the internal components of the circuit breaker.
2. Three Poles: The MCCB with 3P has three separate poles, each capable of interrupting the current flow independently. It allows the breaker to protect three separate electrical phases or circuits simultaneously.
3. Trip Mechanism: The MCCB with 3P employs a trip mechanism that consists of a thermal element and a magnetic element for each pole. The thermal elements respond to overcurrents that persist over a specific duration, such as an overload condition, while the magnetic elements provide rapid tripping for high-level short-circuit currents.
