Circuit breakers play an integral role in the electrical systems they inhabit, and are responsible for protecting against short circuits, overloads and ground faults. One particular circuit breaker, the IUG666-1-64F-30.0-Q-21, is a molded case, thermal-magnetic breaker with standard 3-pole construction and adjustable, short-time trip characteristics. It is suitable for use in residential, commercial and light industrial applications.

The IUG666-1-64F-30.0-Q-21 circuit breaker is rated for 30 amperes and 480 volts. It is suitable for protecting against overloads and ground faults, and has a thermal magnetic trip unit for short circuit protection with adjustable trip characteristics. It also has a manual test circuit, undervoltage release and push-to-trip handle. The IUG-666 has a small footprint and is only 9 inches tall.

The primary purpose of a circuit breaker is to detect a fault condition and interrupt the circuit as soon as possible. The IUG666-1-64F-30.0-Q-21 circuit breaker does this by using a thermal-magnetic trip unit. This trip unit detects an overload or ground fault condition and activates the trip mechanism. If the fault is not corrected in a certain amount of time, the thermal-magnetic trip unit will activate the trip mechanism, thereby cutting power to the circuit.

The thermal-magnetic trip unit works by combining the thermal element and the magnetic element. The thermal element is sensitive to overload or ground fault currents. As the current increases, the thermal element heats up and triggers the trip mechanism. The magnetic element is sensitive to short circuit currents. As the current increases, the magnetic element activates the trip mechanism.

The IUG666-1-64F-30.0-Q-21 circuit breaker also has a manual test circuit which allows for a manual test of the trip characteristics. The undervoltage release allows the circuit breaker to be safely restored after an overcurrent trip has occurred. The push-to-trip handle is used to manually trip the circuit breaker in case of an emergency.

In conclusion, the IUG666-1-64F-30.0-Q-21 circuit breaker is an ideal solution for residential, commercial and light industrial applications. It is a compact, thermal-magnetic circuit breaker with adjustable, short-time trip characteristics, manual test circuit, undervoltage release and push-to-trip handle. It can be used to protect against overloads and ground faults, and can be manually tested to ensure proper protection.
