Screw-in overcurrent switch - S101S, L25A L-25A GHS101 2250 VP0

Overcurrent circuit breaker L-25A is a safety device protecting electrical installations against overloads and short circuits. Mounted in E27 threaded sockets, it replaces traditional fuse links, offering the convenience of resetting after the cause of the problem has been removed. This device, manufactured by Kontakt Simon, is widely used in both domestic and industrial installations.

Characteristics and construction

The L-25A circuit breaker is characterized by a L characteristic, which means it is designed to protect circuits with elements with high inrush current - for example, motors. Inside the device there are two main triggering mechanisms: bimetallic (reacting to overloads) and electromagnetic (reacting to short circuits). The bimetal bends and disconnects the circuit when heated, while the electromagnet immediately cuts off the power supply in the event of a short circuit. This design provides fast and effective protection of the electrical installation. Additionally, this model has a "lug" for sealing, which increases security and prevents unauthorized manipulation.

Application and benefits

The L-25A overcurrent circuit breaker is an ideal solution wherever reliable protection against overloads and short circuits is required. Its compact size and easy installation make it a popular choice among installers. For the end user, this means primarily safety and convenience - no need to replace fuses after every short circuit or overload. The short-circuit breaking capacity at 1500A guarantees protection even in the event of serious failures. The device is designed to operate in circuits with a rated voltage of 230/400 V~ and a rated current of 25A. The degree of protection IP20 provides basic protection against contact with foreign solid objects larger than 12.5 mm.
