IEL1-1REC4-32438-43-V

Circuit breakers are an essential part of electrical protection, providing a vital service in managing the flow of electrical current. A circuit breaker is a switching device that is capable of interrupting an electrical circuit in the event of an overload or short circuit condition. This is done by either manually or automatically cutting off the supply of electricity in the event of an abnormality. The IEL1-1REC4-32438-43-V circuit breaker is a three-pole circuit breaker with adjustable overload and short circuittrip settings. It is a type of electromagnetic circuit breaker which utilises an electromagnetic field to trip the breaker when an overload orshort-circuit condition exists.

The IEL1-1REC4-32438-43-V circuit breaker features adjustable trip time of 6-75 milliseconds as well as adjustable trip current of 5-20 Amps. It also features a built-in surge suppression feature which helps reduce damages caused by electrical spikes due to lightning strikes or power surges. The circuit breaker is also certified for use in hazardous areas meeting the requirements of NEC, UL and CSA safety standards. The breaker complies with NEMA standards for isolation distance and is suitable for branch circuits, motor branch circuits and motor control circuits.

The working principle of the IEL1-1REC4-32438-43-V circuit breaker is based on electromagnetic principles. The circuit breaker consists of a housing containing two sets of contacts – an open ‘switch’ contact and a closed ‘trip’ contact. The breaker also contains a coil or electromagnet. When a circuit fault such as an overload or short circuit occurs, the current through the circuit breaker increases until it reaches the preset trip current. This increases the magnetic field in the coil of the breaker, activating the trip contacts and opening the breaker, isolating the circuit and preventing further damage. The adjustable trip time and trip current settings allow the breaker to be tailored to specific applications.

The IEL1-1REC4-32438-43-V circuit breaker is an essential component of any electrical system as it provides necessary protection against electrical faults such as overloads and short circuits. The adjustable settings of the circuit breaker allow it to be tailored to specific systems and applications, providing an enhanced level of protection and safety. The breaker is also certified for hazardous areas, making it a reliable and safe choice for applications involving explosive atmospheres or flammable vapours.
