Circuit breakers are essential components used to protect an electrical circuit in case of an overload or short circuit. In this article, we will review the IELK 1-1-72-40.0-91-V circuit breaker and its application field, as well as discuss its working principle.

The IELK 1-1-72-40.0-91-V is a small circuit breaker designed for residential and light industrial applications. It is designed to trip and interrupt incoming current when it senses an overload or short circuit. This prevents electrical damage to the circuit and ensures safe operation. It is best used in installations that require higher sensitivity to overcurrent such as control circuit protection and energy metering. The IELK 1-1-72-40.0-91-V is also suitable for nominally high current circuit protection in existing buildings.

The IELK 1-1-72-40.0-91-V is a miniature, thermistor type circuit breaker. It is a completely automatic, self-resetting device that trips at temperatures due to current over current conditions. It features a wide temperature range, as well as overcurrent protection of up to 40 amps. The circuit breaker is equipped with a manual reset override switch that allows the user to manually reset the breaker in the event of an overload or short circuit. It is also equipped with an audible alarm for over current trip indication.

In operation, when an overcurrent condition occurs, the thermistor type circuit breaker will be activated and will trip, opening the circuit and preventing an overload or short circuit. The circuit breaker utilizes a temperature-sensitive bimetal element to detect the overcurrent condition, which changes according to temperature. When the temperature exceeds the set trip point, the bimetal element will activate the trip circuit and trip the breaker. If the problem is a short circuit, the breaker will interrupt the circuit and prevent further damage. If the problem is an overload, the breaker will reduce the current flow to a safe level and return the circuit to normal operation.

The IELK 1-1-72-40.0-91-V is a highly reliable and cost effective circuit protection solution for residential and light industrial applications. It is a versatile circuit breaker that can be used for a wide variety of applications, from household appliances to heating and ventilation systems. It is especially suitable for installations that require higher sensitivity to overcurrent. Its manual reset override switch also ensures safety in operation, as it can be used to manually reset the breaker in the event of an overload or short circuit.
