Circuit breakers are commonly used devices designed to protect circuits from damage due to overloads, short circuits, and other abnormal conditions. The IULNK1-32119-3 circuit breaker is designed for motor applications to protect against damages caused by overloads, overvoltages and undervoltages. It is suitable for branch-circuit protection in residential, commercial and institutional applications.

IULNK1-32119-3 circuit breaker features a compact size, excellent sensitivity and reliable performance. It is designed with a non-interchangeable operating mechanism, interlock system, auxiliary contacts and automatic reset mechanism. The non-interchangeable operating mechanism ensures that the circuit breaker operates within the rated current and voltage range. The interlock system prevents tampering of the breaker and ensures that it is properly installed and operated within specified safety limits. The auxiliary contacts allow for the connection of external devices or sensors to monitor current, voltage and temperature of the protected circuit. The automatic reset mechanism helps in resetting the breaker after trips due to overloads, overvoltages and undervoltages.

IULNK1-32119-3 circuit breaker has a working principle similar to that of other circuit breakers. It consists of a bimetallic strip mechanism, which limits the current to the rated level by automatically disconnecting the circuit in case of thermal overload or short circuit. The bimetallic strip is heated when current passes through it, causing it to expand and trip the breaker. When the current flows through the circuit is lower than the rated value, the bimetallic strip cools down and returns to its original state, allowing the circuit to become live again.

IULNK1-32119-3 circuit breaker is mainly used in motor applications. It is typically used as an overload protector in residential, commercial and institutional buildings, where it prevents major electrical damages due to overloads, short circuits or other abnormal conditions. It is also used in heating and air conditioning systems, electrical motors and elevators in both domestic and industrial applications.

In conclusion, IULNK1-32119-3 circuit breaker is a reliable device that provides protection against overloads, overvoltages and undervoltages in motor applications. It is designed with a non-interchangeable operating mechanism, an interlock system, auxiliary contacts and an automatic reset mechanism. Its working principle is based on a bimetallic strip, which is heated when the current passes through it. As a result, it trips the breaker when the current exceeds the rated value. IULNK1-32119-3 circuit breaker is mainly used in residential, commercial and institutional buildings, as well as in heating and air conditioning systems, electrical motors and elevators.
