IULHK1111-1-43-50.0-AB-01 Circuit Protection

Circuit breakers have been used in electrical systems for over a century. These devices protect electrical circuits from damage caused by excessive current, voltage, and/or temperature. One type of circuit breaker is IULHK1111-1-43-50.0-AB-01.

The IULHK1111-1-43-50.0-AB-01 is a type of air-magnetic circuit breaker. It is designed to protect power distribution circuits and is specifically intended for branch circuits of 480V AC or less. It is UL 489 listed and CSA certified, providing a system with superior safety protection. It has the capability to handle up to ten overloads and short-circuits before it trips, providing protection for the circuit.

The basic principle of the IULHK1111-1-43-50.0-AB-01 is the same as other types of circuit breakers. This type of circuit breaker has an arc chute with an arc shorting device and a thermal magnetic trip unit. This trip unit utilizes both thermal and magnetic forces to open the circuit when the specified amp rating is exceeded.

The thermal magnetic trip unit implements a combination of both thermal overload and magnetic short-circuit protection. The thermal overload protection is activated when the current reaches a certain level. The magnetic short-circuit protection is activated when short-circuits occur and the response time is below 10ms.

When the IULHK1111-1-43-50.0-AB-01 circuit breaker is tripped, it opens the circuit and disconnects the power. This protects the circuit from damage by preventing overloads or short-circuits. The circuit breaker can also be manually reset, allowing power to be reconnected after the issue has been resolved.

The IULHK1111-1-43-50.0-AB-01 is ideal for use in general-purpose power circuits. It is particularly suitable for applications such as panel boards, switchgear assemblies, and motor control centers. It also meets most industrial requirements for breaker applications with its high interrupting capacity, allowing it to satisfy a wide range of applications.

The IULHK1111-1-43-50.0-AB-01 is a reliable and efficient device capable of protecting power circuits from damage. Its thermal-magnetic trip unit, arc chute, and arc shorting device provide superior protection. This device is suitable for a range of applications, including panel boards, switchgear assemblies, and motor control centers.
