Circuit breakers are ubiquitous pieces of safety equipment designed to protect buildings and devices against damage caused by the excessive flow of electricity. The IULH111-1REC4-42F-40.0-01 circuit breaker is a specific model manufactured by Vertical Manufacturing, Inc. that possess unique characteristics suited for protecting a broad range of applications.

The IULH111-1REC4-42F-40.0-01 circuit breaker is designed to protect equipment from over-current damage by interrupting an electrical current at a predetermined current rating. It is designed to close instantly when the over-current situation is resolved, restoring service as soon as possible. This model features a nominal voltage rating of 480V AC, and a nominal current rating of 40.0A.

The IULH111-1REC4-42F-40.0-01 circuit breaker is particularly well-suited for applications subject to frequent short circuits and current overloads. It features a trip-free mechanism that prevents it from being pulled out or shoehorned into an off position, helping to ensure that the circuit breaker functions precisely as designed. This circuit breaker is also designed to minimize the risk of nuisance tripping, as it features a thermal-Magnetic trip unit.

When current flows through the IULH111-1REC4-42F-40.0-01 circuit breaker, it generates heat. This causes the thermal-Magnetic trip unit to open the contacts, interrupting the current and thus preventing thermal or electrical overloads. Once the current has dropped and the device has cooled, the tripping unit re-engages and the breaker is reset. In this way, the IULH111-1REC4-42F-40.0-01 can perform its duty as a reliable protection device.

The IULH111-1REC4-42F-40.0-01 is approved for use in controlling most load types in a variety of industrial arenas. These include motors, transformers, UPS systems, conveyor systems, air conditioners, and other low voltage AC motor-operating devices. In addition, the breaker is suitable for use in residential applications such as lighting and HVAC systems. The breaker is also approved for commercial applications such as fire pumps and emergency lighting.

The IULH111-1REC4-42F-40.0-01 circuit breaker offers reliable protection against excessive current flow and is well suited for residential, commercial and industrial applications. Its high current rating makes it an ideal choice for applications such as motors, transformers, UPS systems, and HVAC systems that experience frequent short circuits and current overloads. The breaker’s unique trip-free mechanism and thermal-Magnetic trip unit allows it to outperform traditional circuit breaker models in terms of providing reliable and safe protection.
