Air circuit breaker WEW1-1600 breaker withdrawable type acb fixed type 400VAC/690VAC 1600 amp 3/4p acb

400V air circuit breakers are characterized by a range of features that make them well-suited for a diverse array of applications. Some of the key features include:

1. Current Rating: 400V air circuit breakers are available in a wide range of current ratings, typically ranging from 1000A to 7500A. This broad spectrum of current-carrying capacities allows these circuit breakers to cater to the varying needs of different electrical systems, from small-scale installations to large industrial setups.

2. Voltage Rating: As the name suggests, 400V air circuit breakers are designed to operate at a voltage of 400V, making them ideal for low voltage applications commonly found in industrial and commercial settings.

3. Trip Unit: These circuit breakers are equipped with advanced trip units that provide precise and reliable protection against overloads and short circuits. The trip unit is responsible for detecting abnormal electrical conditions and initiating the tripping mechanism to interrupt the current flow when necessary.

4. Breaking Capacity: 400V air circuit breakers are engineered to have high breaking capacities, allowing them to safely interrupt fault currents and protect the electrical system from damage. This feature is crucial in ensuring the overall reliability and safety of the circuit breaker.

5. Modular Design: Many 400V air circuit breakers feature a modular design, which allows for easy installation, maintenance, and expansion of the electrical system. The modular construction also facilitates quick and efficient replacement of components, minimizing downtime and enhancing the overall reliability of the circuit breaker.
