IULBXK11-35271-90 is a circuit breaker, which is an electromechanical device designed to protect electrical circuits from damage due to overload, short circuit and ground faults. It acts like an automatic switch, that when current flows through it reaches a certain level it will automatically break the circuit and thus protect the other components in the circuit from getting damaged.

The term “circuit breaker” is derived from the fact that it is the device that actually “breaks” the circuit. It is also sometimes referred to as an overcurrent protective device (OCPD). The way it works is by sensing the current flowing through the circuit and if it exceeds the pre-set limit, it opens the circuit. The limit is generally set by a user. In the case of the IULBXK11-35271-90, the maximum current is 90 amperes.

In this circuit breaker, the current sensing is done by the use of a thermal magnetic device. This device contains two elements: a thermal element and a magnetic element. The thermal element is a bimetallic strip and detects the overload, while the magnetic element consists of an electromagnet with its core connected to a spring-loaded armature. When an overload is detected, the temperature of the bimetallic strip increases and causes the overcurrent trip mechanism to engage. The magnetic element then acts on the spring-loaded armature to open the circuit. It will remain in this open state until either the current drops below the trip point or the switch is reset manually.

In addition to the protection from overload and short circuit faults, circuit breakers are also used to provide ground fault protection. When a ground fault occurs, a current flows from the grounded point to another point in the circuit that produces a magnetic field. This magnetic field is sensed by the circuit breaker and then it trips the breaker and shuts off the current.

The IULBXK11-35271-90 circuit breaker can be used in a variety of applications including home, commercial and industrial settings. It is an effective way to protect against the dangers associated with electrical circuits and will provide reliable protection in any setting.
