IULHK111-1-42-5.00-B-91

Circuit Breakers are devices used to protect electrical circuits. The IULHK111-1-42-5.00-B-91 is an example of one such circuit breaker. It is designed to be used in systems that require precise, high-voltage switching. The device operates by breaking an electrical circuit on the occurrence of an over-current or short-circuit event. This allows the current to be stopped before it damages other components in the circuit.

The IULHK111-1-42-5.00-B-91 is a short-circuit breaker, which means that it is used to protect a circuit against short-circuits and over-currents. The device works by utilizing thermally or electromechanically operated contacts that open the circuit when an over-current or short-circuit event is detected. The device is equipped with a MOV (metal-oxide varistor) to absorb the surge current that occurs during an over-current or short-circuit event, protecting both the circuit and the device. When the surge current is detected, the MOV is tripped, and the contacts open the circuit, thereby protecting the circuit from further damage.

The IULHK111-1-42-5.00-B-91 is suitable for applications that require high-voltage switching in systems with low-voltage circuits. These include automotive systems, air-conditioning systems, and home appliance systems. The device is especially suited for industrial applications that have a high number of switching cycles, such as manufacturing automation, pharmaceutical equipment, and power supplies.

In addition to protecting the circuit from over-current and short-circuit events, the IULHK111-1-42-5.00-B-91 also provides shock and arc protection. It is designed with an arc chamber and a surge suppressor that reduce the amount of current that passes through it, thereby minimizing the risk of a circuit fire. The circuit breaker also features an isolation switch, which is used to circumvent a system during maintenance or repair.

The IULHK111-1-42-5.00-B-91 is a reliable device that is designed to withstand the rigors of everyday use. It is rated at 40Amps, and is UL and CSA approved. The device is sealed and shaded to prevent the ingress of dust and moisture. It is also designed to meet the standards of both the National Electrical Code and Canadian Electrical Code.
