Circuit breakers are essential safety components for many electrical circuits. They are designed to protect against damage due to overcurrents, or when too much electric current is flowing through an electrical circuit. In some cases, they can prevent fires and other serious accidents. The PP11-1-20.0A-OB is an example of a circuit breaker, and this article will explain its application field and working principle.

The PP11-1-20.0A-OB is a multiple-pole circuit breaker. It is typically used in lighting panel, power distribution or service panels, or industrial control systems. It is designed to trip, or disconnect the circuit, if a fault current of 20.0 amperes is detected. In single-phase applications, it is mounted in a standard push-in, open-mount circuit breaker panel, where it is rated for 120 Vac.

The PP11-1-20.0A-OB has an integrated Current Trip Coil (CTC). This is an electronic device which detects the fault current and trips the breaker, when the current approaches or goes over the set current limit. The CTC works by sensing the electrical field resulting from the fault current. When the field exceeds a certain threshold, the CTC will actuate the trip mechanism in the breaker.

The PP11-1-20.0A-OB features a positively driven overcurrent trip release mechanism. This ensures that the breaker trips quickly, reliably and consistently. The breaker also features a load current-sensing device which accurately detects the fault current and trips the breaker accordingly. The load-current sensing device enables the PP11-1-20.0A-OB to trip at a lower current than is required by other types of breakers.

The PP11-1-20.0A-OB circuit breaker also has an adjustable time delay function. This function allows the user to adjust the time setting on the breaker, so that it will trip at a specified time setting; this helps to protect against nuisance tripping. Additionally, the PP11-1-20.0A-OB has a manual reset function, which enables the user to quickly reset the breaker without having to power down the system or the individual circuit.

In conclusion, the PP11-1-20.0A-OB is a multiple-pole circuit breaker which is typically used in lighting panel, power distribution or service panels, or industrial control systems. It features a Current Trip Coil, a load current-sensing device, and an adjustable time delay function. Furthermore, it has a manually resettable function which can be used to quickly reset the circuit breaker without having to power down the system. The PP11-1-20.0A-OB is an effective and reliable way to protect against excessive current in an electrical system.
