IULR1-1-52-.250-91

Circuit breakers are an important element of electrical engineering, providing protection against short circuits, overloads and incorrect wiring. The IULR1-1-52-.250-91, or UL1077, is a device designed to interrupt current flow to reduce electrical damage in case of a short circuit, overload, or incorrect wiring. These are commonly used in both residential and commercial settings such as home theaters, offices, and laboratories.

The IULR1-1-52-.250-91 is a single pole, two-wired circuit breaker. This is rated for a continuous current of 25A and an instantaneous current of 125A. It has an interrupt rating of 2500A and a short circuit current rating (SCCR) of 35kA. These ratings are dependent upon a series of factors such as conductor size, wire length, and the amount of current the device will be handling. This device is UL listed and CSA approved.

The IULR1-1-52-.250-91 circuit breaker is primarily used in applications that require overcurrent and short circuit protection. These applications may include home theaters, offices, laboratories and other locations where any type of electronic or electrical equipment may be used. The device is also used in power distribution and motor control panels.

The working principle of the IULR1-1-52-.250-91 is fairly simple. When an overload is detected, the heater element within the device heats up, expanding the contacts and separating them to interrupt the current flow. The contacts that form the thermal cut-off remain closed until the heater cools down and returns to its original state. This process is repeated until the fault is cleared. If the fault remains and the current continues to flow, then the SCCR rating of the device will be exceeded and the circuit breaker will trip.

The IULR1-1-52-.250-91 is a reliable and economical way to provide circuit protection. It is relatively easy to install and provides a higher level of protection than other common circuit breakers due to its UL listing and CSA certification. This device is also relatively inexpensive, so it is a good choice for applications in both residential and commercial settings that require circuit protection.
