Circuit breakers, also known as circuit interrupters, are devices used to interrupt an electrical circuit to prevent a hazardous overload or short-circuit from occurring. The LELK1-1REC4-30326-45 is a type of circuit breaker that is used to protect sensitive and expensive equipment from the most common types of electrical overloads and faults. This circuit breaker features a contact- and frame-mounted design for easy installation and maintenance, solid-state components for optimal reliability, and combined overcurrent and short-circuit protection for maximum protection.

The LELK1-1REC4-30326-45 is designed primarily for use in industrial and manufacturing environments. It is ideal for use in applications that require reliable and sensitive circuit protection, such as high-power manufacturing processes, robotic and automated systems, and automated process controls. The LELK1-1REC4-30326-45 can also be used in general laboratory applications, such as for scientific testing, data collection and analysis.

The working principle of the LELK1-1REC4-30326-45 is based on overcurrent and short-circuit protection. It has two elements: a circuit breaker contact system, and a trip unit. The circuit breaker contact system contains a set of contacts that are held open until current reaches a set level and trips the contacts, interrupting the circuit and preventing dangerous overloads or short-circuits. The trip unit contains a sensor, relay coils, and a trip relay. When the current reaches a predetermined level, the sensor sends a signal to the trip relay, which then activates the trip coils and causes the contacts to open, breaking the circuit.
