Circuit breakers are widely used in a variety of electrical applications, from industrial and commercial to residential, to provide an effective means to protect electrical devices, systems and components against damage. Among the most widely used type of circuit breaker is the LELK1-1-69-60.0-U-91.

The LELK1-1-69-60.0-U-91 is a 1-pole, 690 V AC/250 V DC voltage type circuit breaker. It is designed for both indoor and outdoor use, as it is weatherproof and waterproof. The breaker has a total rating of 60 A, with a self-trip mode of 65 A. The breaker is equipped with an adjustable trip-free temperature compensation and overcurrent protection. The LELK1-1-69-60.0-U-91 also features an overload, short-circuit and ground fault protection.

The working principle of the LELK1-1-69-60.0-U-91 circuit breaker relies on the use of two separate contacts. When the two contacts are in contact, the circuit is complete and current flows through the circuit. When too much current is passed through the circuit, the contacts will open, effectively disconnecting the circuit and preventing any further damage or harm to the electrical components.

The LELK1-1-69-60.0-U-91 is often used in areas where the amp rating is typically lower, such as in home and small business applications. Its low amp capabilities make it good for low voltage applications, too. It is also used in industrial and commercial applications, such as machine tools, motor control systems and other industrial or commercial equipment.

The breaker is a type C circuit breaker, meaning it complies with UL 489 and CSA STD C22.2 No. 5-04 standards, and is suitable for use in branch circuits, control circuits, and motor branch circuit control of AC operated equipment.

In residential applications, the LELK1-1-69-60.0-U-91 is used in homes to protect appliances, lighting fixtures and other equipment. In commercial and industrial applications, they provide containment of energy, especially in enclosed areas. They are also used to match the fast-fault conditions of large 3-phase power lines and to protect three-phase motors.

The LELK1-1-69-60.0-U-91 is designed for a high level of reliability and provides long-term operation in its rated environment. This circuit breaker can be used in environments with a wide range of temperatures and operating conditions, allowing for greater protection of the electrical components and systems from potentially hazardous conditions.
