IULK1-1REC4-32874-4

IULK1-1REC4-32874-4 circuit breakers are widely employed in the power distribution systems and power plants, functioning as protective devices for electrical components against hazardous faults. It can provide both control of circuit elements and protection, significantly improving reliability and cost of power system operation.

Circuit breakers are electrical protection devices which are used to open and close electric circuits under normal and abnormal conditions. To provide reliable and safe protection for the different types of electrical components, a circuit breaker must be suited for its given environment. To achieve that, various types of circuit breakers have been developed, classified by their electrical current rating, operating mode, type of operation, and type of insulation. IULK1-1REC4-32874-4 is one of these circuit breakers and also happens to be the most versatile one, since it is designed to provide both overcurrent and short-circuit protection.

The working principle of IULK1-1REC4-32874-4 is based on the interaction of two components; the actuating solenoid and the tripping device. The tripping device is designed to detect an abnormal condition, either overcurrent condition or a fault, in the circuit. When it detects the abnormal condition, it sends an electric signal to the actuating solenoid which is then activated. The actuating solenoid then triggers an internal switching mechanism to open the circuit breaker.

The IULK1-1REC4-32874-4 has a current rating of up to 500A and a voltage rating of up to 600VAC. It is suitable for use in residential, commercial and industrial applications. This breaker has two contact configurations, a single pole and a double pole. For single pole configurations, it features a separate pole-operated contact spring which can be configured for continuous current carrying or load control functions. For double pole configurations, the contacts are interconnected by common springs with the pole-operated contact spring offering the same function as single pole.

The IULK1-1REC4-32874-4 also features an optional adjustable overcurrent trip switch for instantaneous or delayed trip settings. This adjustable trip switch has a wide range of current settings and can be pre-set for optimal performance. Additionally, this circuit breaker is equipped with a high-speed surge suppressor to protect against abnormal voltage conditions and a thermal protection device to reduce overheating.

The IULK1-1REC4-32874-4 circuit breaker is a versatile device, capable of providing safe and reliable protection to the connected electrical components. It comes with adjustable trip settings, high speed surge protection and thermal protection, making it suitable for use in a wide range of applications. Furthermore, due to its small size and lightweight nature, it is easy to transport and install. As a result, these circuit breakers are a popular choice in many power distribution systems and power plants.
