The IULN21-1REC4-27899-3 is a type of circuit breaker, which is designed to protect electric circuits from overloads and sudden power surge events. This circuit breaker is made up of three distinct parts: the sensing component, the control component, and the trip mechanism. The sensing component consists of either a metal oxide varistor (MOV) or a gas discharge tube (GDT) that continuously senses the voltage and current flowing through the circuit. If these readings surpass a pre-determined threshold, then the control component will activate the trip mechanism, which will abruptly stop the flow of electricity through the circuit.

The IULN21-1REC4-27899-3 is mainly used in industrial applications, such as power plants, where it is used to ensure the safe operation of electrical equipment. It is also used in residential applications, such as in the protection of home appliances against power surges. The IULN21-1REC4-27899-3 works in three modes: over-current protection, short-circuit protection, and thermal protection. In over-current protection, the circuit breaker senses when the current passing through the circuit exceeds a certain level, and trips to instantly shut off the flow of electricity within the circuit. In short-circuit protection, it senses when the voltage drops quickly and trips to cut off the power to the circuit. In thermal protection, it senses the overheating of the circuit caused by prolonged excessive current and trips to prevent damage to the circuit. In addition, the IULN21-1REC4-27899-3 has an adjustable tripping time to allow for different levels of protection.

The IULN21-1REC4-27899-3 is designed to be used in both indoor and outdoor applications, and is rated to operate at up to 460 volts. It comes in several configurations to accommodate different load requirements depending on the application, such as motor applications, consumer protection, and power flow control. It is also designed with a quick-connect feature, allowing the user to install the circuit breaker quickly and easily in the application. It is made up of two parts: the main body and the trip unit. The main body is usually located in the circuit breaker panel, and the trip unit is located in the circuit breaker enclosure.

The IULN21-1REC4-27899-3 is a high-performance, reliable circuit breaker that provides dependable protection from power surges, short circuits, and overloads. It features several safety features, such as fast trip response time, adjustable trip time, and visual indication for trip. The IULN21-1REC4-27899-3 is widely used in industrial and residential applications for reliable circuit protection. It is also equipped with an internal fuse, and can be mounted in any orientation for flexible installation.
