Circuit breakers are designed to protect electrical circuits from damage caused by overload or short circuit conditions. The APG1-34931-3 circuit breaker is a general purpose, three pole, double break type with adjustable trip settings from 0.3 to 13.0A. This breaker is typically used for residential and commercial applications.

The three poles of the APG1-34931-3 are physically linked together, providing fully coordinated protection. When a fault is detected, each pole is independently interrupted, allowing time for the fault current to be cleared before any further damage can occur.

The adjustable trip settings of the APG1-34931-3 takes account of the different characteristics of resistive, inductive, and capacitive loads. This ensures that the breaker will trip at an appropriate level, providing protection without frequent nuisance tripping. The adjustable trip settings allow the breaker to be tweaked to the required conditions of each particular installation.

The dielectric strength of the APG1-34931-3 circuit breaker is 1.2kV and it contains an integral Test button that allows it to be manually tested for the correct operation. In addition, the connection terminals are designed to accept wide range of wiring configurations and accommodates both stranded and solid conductor types.

The APG1-34931-3 is suitable for branch circuit or low voltage external source protection applications. It is also UL listed to 10,000A for power circuit applications. This wide range of uses for the device shows its "flexibility" when two or more types of load must be protected.

Further protection is provided by the inclusion of a mechanism that senses rapid changes in voltage. This prevents tripping due to momentary high-voltage transients. Also, the device features a thermal magnetic trip mechanism, which is designed to reduce trips due to extended overloads or short circuits.

In summary, the APG1-34931-3 is a powerful and reliable general purpose circuit breaker that provides a high level of protection at an affordable cost. The adjustable trip settings, integrated test button, and the robust construction of the unit make it a reliable choice for both residential and commercial applications. It is also suitable for applications requiring frequent resetting, such as fuse holders.
