IULBXB11-37222-30

Circuit breakers are a fundamental component of any electrical system and are used in a variety of different applications. The IULBXB11-37222-30 is a specific type of circuit breaker designed for a variety of high amperage and high voltage applications. It is designed to break an electrical circuit when there is an overload or short circuit, providing protection for both equipment and personnel.

The IULBXB11-37222-30 circuit breaker is a three-pole circuit breaker rated for up to 6300A. It can handle a maximum voltage of 600VAC and is intended to be used in applications that require high interruption capacity. It is UL489 listed, making it suitable for use in a variety of high amperage, high voltage applications such as industrial process automation, railway signaling, and similar applications.

The working principle of the IULBXB11-37222-30 circuit breaker is relatively simple. A metal linkage is attached to the breaker, which is connected to the trigger mechanism. When an overload or short circuit is detected, the trigger mechanism causes the metal linkage to move, breaking the circuit and preventing the current from flowing. The device uses a combination of heat and pressure to ensure proper operation. The heat dissipated through the breaker trips a thermal protection switch, which in turn de-energizes the contacts in the device and breaks the circuit. The pressure from the interrupted current is then vented through the breaker.

The IULBXB11-37222-30 circuit breaker is designed to provide the necessary protection in a variety of applications. It is suitable for use in systems with low, medium, and high voltage, and can handle loads of up to 6300A. It features both instantaneous and delayed trip characteristics, ensuring that any current overloads or short circuits are detected and the circuit is broken as soon as possible. The device also features a circuit breaker lockout feature, which ensures that the circuit will not be reset until it is manually overridden.

The IULBXB11-37222-30 circuit breaker is a reliable and highly efficient device, making it ideal for a variety of applications. It is designed to provide both personnel and equipment with the necessary protection, and has the added benefit of being both UL489 listed and CE marked for European safety standards.
