APL111-3R-29458-1

Circuit Breakers have been thought of as a form of protection for electrical circuits for many decades. The APL111-3R-29458-1 is an example of one such type of circuit breaker.

The application field of the APL111-3R-29458-1 circuit breaker is mainly to provide thermal overload protection for four-pole circuit breakers in industrial and commercial applications. It is also suitable for disconnection and short-circuit protection of low-voltage circuits. These applications include commercial and industrial AC power transmission, DC power transmission, and motor control circuits.

The APL111-3R-29458-1 circuit breaker’s working principle is based on the thermal-magnetic methodology. The thermal-magnetic principle uses a combination of heat and magnetism to trip the circuit breaker. When the circuit breaker is called into operation due to an overcurrent the current causes the heat generated by the breaker to increase. This causes part of the magnetic coil’s iron core to expand and move apart from the body of the coil in response. This triggers the magnetic mechanism that forces the contacts of the breaker open. This effectively interrupts the circuit and stops the flow of electricity to protect the circuit from further damage.

Additional features of the APL111-3R-29458-1 circuit breaker include its push-on-push-off operation for manual tripping, and its trip-free design. The push-on-push-off operation allows the user to manually trip the breaker, and the trip-free design ensures that the breaker trips completely even when the load is still connected. This helps to reduce the number of restart attempts.

The APL111-3R-29458-1 circuit breaker is designed for easy installation and use. It is a UL 1066 Low Voltage safety system and is rated to protect systems of up to 28V. In addition, the breaker is manufactured with high-quality materials and is tested to UL standards to ensure safety and reliability. The APL111-3R-29458-1 circuit breaker is designed to provide reliable protection and is suitable for use in a variety of industrial and commercial applications.
