Review ITE Fused Circuit Breaker 400a/3 Pole/600vac 400trip

The ITE CJ3-B400 is a high-performance, industrial-grade, three-pole fused circuit breaker designed for applications requiring heavy electrical loads up to 400 amps at a voltage rating of 600 volts AC. This circuit breaker is ideal for use in industrial, commercial, and large residential electrical systems where reliable tripping and overload protection are crucial.

The CJ3-B400 is a 400 amp trip breaker, which means it is designed to automatically trip and disconnect the electrical circuit when the current flowing through it exceeds the rated value, preventing potential damage to the wiring, equipment, or even causing a fire. The breaker features a 400 amp current rating, allowing it to handle large electrical loads without compromising safety or efficiency.

This circuit breaker is a three-pole design, meaning it can control the flow of current through three separate circuits, making it suitable for applications requiring the protection and control of multiple electrical loads. The breaker's 600 volt AC voltage rating ensures it can handle high voltage applications, providing increased safety and peace of mind.

The ITE CJ3-B400 is equipped with a fused disconnect switch that provides an additional level of safety by isolating the circuit from the power source when the breaker is open. The fuse element melts when the current exceeds the rated value, thereby protecting the circuit breaker and connected wiring from further damage.

This circuit breaker is designed with a rugged construction to withstand the rigors of industrial and commercial environments. It is suitable for indoor and outdoor installations, making it a versatile solution for a wide range of applications. The CJ3-B400 is also UL listed, ensuring it meets the highest standards for safety and reliability.

The ITE CJ3-B400 offers easy installation and maintenance, with a clear and accessible trip handle, as well as a removable handle for easier maintenance access. The breaker's mechanical trip mechanism ensures accurate and reliable tripping, providing enhanced safety and protection for your electrical system.

In summary, the ITE CJ3-B400 is a high-performance, three-pole fused circuit breaker designed for applications requiring heavy electrical loads up to 400 amps at a voltage rating of 600 volts AC. Its rugged construction, easy installation and maintenance, and reliable tripping mechanism make it an ideal solution for industrial, commercial, and large residential electrical systems.

Pros and Cons of Buying a ITE CJ3-B400 Fused Circuit Breaker

The ITE CJ3-B400 is a 400A/3 pole/600VAC fused circuit breaker designed for heavy industrial applications. It offers 400 amps of current capacity and is rated for 400 volts AC. This circuit breaker trips at 400 amps and is equipped with a fuse, providing an additional layer of protection against short circuits.

a) Enhanced Safety: The ITE CJ3-B400 circuit breaker comes with a built-in fuse that provides an additional safety feature. In case of a short circuit, the fuse melts and opens the circuit, preventing further damage to the electrical system and potential hazards.

b) High Current Capacity: With a 400A current capacity, this circuit breaker can handle heavy loads, making it suitable for demanding industrial applications.

c) 3-Pole Design: The 3-pole design of the ITE CJ3-B400 circuit breaker ensures that all three phases of a power system are protected, ensuring a balanced and efficient electrical load.

d) Easy Installation: The circuit breaker is designed to be easily installed in a standard NEMA 1, 2, 3R, 3S, 4, 6, 12, 13, or 13S enclosure, making it a versatile option for various electrical systems.

a) Higher Cost: Compared to standard circuit breakers without a fuse, the ITE CJ3-B400's integrated fuse may result in a higher initial investment.

b) Increased Complexity: The addition of a fuse in the circuit breaker design may add complexity to installation, maintenance, and troubleshooting.

c) Limited Compatibility: The ITE CJ3-B400 circuit breaker is designed for specific applications and voltage levels, limiting its compatibility with various electrical systems.

When considering the purchase of an ITE CJ3-B400 fused circuit breaker, it is essential to weigh the benefits against the potential drawbacks. The enhanced safety provided by the integrated fuse, high current capacity, and 3-pole design make it an attractive option for industrial applications. However, the higher cost and increased complexity may deter some users. Ultimately, the decision to buy this circuit breaker should be based on the specific needs and requirements of the electrical system in question.

If you are looking for a circuit breaker with an integrated fuse and high current capacity for heavy industrial applications, the ITE CJ3-B400 could be an excellent choice. However, it's essential to consider the potential drawbacks, including the higher cost and increased complexity, before making a final decision. Always consult with a qualified electrician or electrical engineer to ensure that the circuit breaker is the best solution for your specific application.
