Circuit breaker 125a 4 poles mcb
A specific type of circuit breaker!
A 125A, 4-pole MCB (Miniature Circuit Breaker) is a type of electrical protection device that is commonly used in electrical distribution systems. Here's a breakdown of the specifications:
125A: The current rating of the MCB is 125 amperes (A). This means it can handle a maximum current of 125A without tripping.
4-pole: The MCB has four poles, which means it can control four separate circuits or phases. This is useful in applications where multiple circuits need to be protected simultaneously.
MCB (Miniature Circuit Breaker): An MCB is a type of circuit breaker that is designed to be compact and lightweight. It is typically used in residential, commercial, and industrial applications where a higher level of electrical protection is required.
Some common features of a 125A, 4-pole MCB include:
- Overcurrent protection: The MCB will trip and disconnect the power supply if the current exceeds the rated value of 125A.
- Short-circuit protection: The MCB will also trip if a short circuit occurs, which can help prevent damage to equipment and reduce the risk of electrical shock.
- Thermal protection: The MCB may also have thermal protection, which can detect overheating and trip the circuit to prevent damage to the equipment.
- Resettable: Most MCBs are resettable, meaning that once the fault is cleared, the MCB can be reset to restore power to the circuit.
Some common applications for a 125A, 4-pole MCB include:
- Industrial control panels
- Commercial electrical distribution systems
- Residential electrical distribution systems
- Data centers
- Telecommunications equipment
When selecting a 125A, 4-pole MCB, it's important to ensure that it meets the specific requirements of your application, including the maximum current rating, voltage rating, and environmental conditions. It's also important to follow proper installation and maintenance procedures to ensure the safe and reliable operation of the MCB.
