Circuit Breakers

Circuit Breakers are widely used in various electrical systems to protect them from overcurrents, ground faults and other potential damage. The IPAH-11-1-52-20.0-A-01 is a type of circuit breaker which is mainly used in low voltage power distribution systems.

This circuit breaker is designed to detect any fault in the power circuit and switch off the power supply. It consists of two main parts: a special electrical contact system and a thermal trip device. The electrical contact system supporting the magnets or switches provides the main building blocks for assessing the quality of the current path and in response, takes corrective steps.

The contact system is made up of three main components: the interface block, the armature, and the linkage. The interface block houses a set of two electrical contacts: the contact bridge, which transfers the power from the incoming power line to the output, and the resetting bar, which is connected to the bridge. When the current exceeds the rated level, the resetting bar is pushed off its place, breaking the circuit.

The armature is a movable part that is either three-lobed or two-lobed depending on the requested performance of the circuit breaker. It has a set of movable magnets, which interact with the resetting bar of the interface block. Whenever the system detects an overload or a short circuit, the corresponding magnets attracted by the resetting bar cause the armature to move, and the circuit breaker trips.

The linkage is responsible for encoding the amount of potential energy required to move the circuit breaker. This part is also responsible for the reliable resetting of the circuit breaker to restore the interrupted electrical circuit. The linkage is designed to be tamper-resistant, and only actuators linked to the manufacturer-designated safety network can reset the circuit breaker.

The thermal trip device is an additional protection tool that shuts off the power supply in the event of an overload. It works with the help of a bi-metallic strip, which is heated up by the current passing through it. When the temperature reaches a certain level, the strip bends and the contact point snaps back into place, opening up the circuit.

The IPAH-11-1-52-20.0-A-01 is a reliable, cost-effective, and easy-to-install circuit breaker with a simple operating mechanism. Its robust but compact construction makes it highly suitable for safe and efficient protection of low voltage power distribution systems. It is also compliant with many applicable IEC and NEMA standards.
