CB187F-50 Circuit Protection

CB187F-50 Application Field and Working Principle

CB187F-50 is one of the most frequently used circuit breaker which is designed to protect the residential, office and other commercial building circuits. To ensure its reliable performance, the circuit breaker is produced according to the latest UL and ANSI standards. In addition, this breaker also features high electrical rating, visual operation indication and better interrupting capacities.

Application Field

The CB187F-50 can be applied in a wide range of applications, including overload and short circuit protection, motor control and compressor starting, and other applications which have voltage ratings of 120/240V, 125V and 277VAC. It is suitable for a variety of residential and commercial applications. Moreover, it can be used with either 120/240V or 277V Single Pole and 6P 120/240V or 4P 277V lighting or appliance circuits.

Working Principle

The CB187F-50 operates in such a way that when the circuit is overloaded or short-circuited, its current-limiting mechanism will activate the arc-fault safety device, causing the breaker to open. This way, the breaker can prevent further damage to the circuit while still providing enough power to the appliance or equipment connected to the circuit.

The CB187F-50 also features a trip-free design, meaning that the breaker will open regardless of whether the breaker handle is in the on or off position. This feature can help to avoid potential danger caused by a user mistakenly leaving the breaker in the on position and not being able to shut off the power in the case of an emergency.

The CB187F-50 also has a thermal-magnetic trip assembly, which monitors the breaker temperature and the current of the circuit. If either exceeds their limit, the breaker trips, reducing the risk of fire or other potential dangers.

To ensure reliable performance, the CB187F-50 is designed with a self-testing feature. This feature checks the operation of the breaker, enabling it to detect potential problems with the breaker’s operation before it becomes a serious safety hazard.

Conclusion

The CB187F-50 is a reliable and safe circuit breaker that is suitable for a wide range of applications. Its features ensure its reliable performance and make it one of the most popular choices for circuit breaker protection.
