Circuit breakers are the backbone of any electrical system, providing overcurrent protection and ensuring the safe, reliable operation of any electrical system. The CB174-20 is a non-air-break circuit breaker designed to provide rated short-circuit current protection (SSIP) and adjustable overcurrent protection (OCP) for branch-circuit and distribution applications. This breaker is ideal for any light-industrial or commercial facility that needs the flexibility of up to 20 amperes of current protection.

The CB174-20 offers a flexible design that allows for multiple options, including adjustable time delay, offset tripping and optional motor control accessories. The breaker also has a built-in ground fault circuit interrupter (GFCI) that provides additional protection from ground faults. The CB174-20 also offers a UL rated switch that can be operated manually or remotely via a remote contactor. The breaker\'s UL rating also includes UL1077-compliant emergency stop (E-stop) protection for use when power interruption is necessary.

The CB174-20 is versatile enough to be used in a wide range of industrial, commercial and residential applications. In industrial applications, the breaker can be used to protect everything from motors to stage lighting to sensitive automation equipment. Its adjustable trip currents and time delay make it an ideal choice for providing overcurrent protection for motors. In commercial applications, the breaker can be used to protect machinery and electronic equipment from overcurrent and undercurrent faults.

The CB174-20 operates on the basic principles of electromagnetism. When current passes through the breaker, a magnetic field is created which causes a plunger to move. This plunger opens a mechanical contact in the circuit, effectively breaking the circuit and preventing the flow of current. The breaker also has a built-in thermal cut-off feature that limits the continuous current flow, protecting against potential thermal overloads.

The CB174-20 is a versatile and reliable breaker that can be used in a variety of applications. It provides overcurrent protection and adjustable time delay, as well as built-in E-stop protection and optional motor control accessories. Its adjustable trip currents and time delay make it an ideal choice for motors, while its UL rating ensures reliable operation in commercial and industrial applications.
