Screw-in overcurrent switch with sealing ear, L20A L-20A GHS101 2200 VP9203

Overcurrent protection switch – reliable protection for electrical installations

The screw-in overcurrent switch L-20A is a solid and practical solution for protecting electrical circuits. It replaces traditional fuse links, offering the convenience of resetting after activation. Installation is simple – the switch screws into an E27 fuse socket or is mounted directly on the distribution board.

Application and functionality

The device is designed to protect against overloads and short circuits in electrical installations with a rated voltage of 230/400V. Its rated current is 20A, and the short-circuit capacity reaches 1500A, guaranteeing effective protection of connected devices. The L-type tripping characteristic provides a delayed response to short-term current surges, which is particularly important when starting devices with motors. The black button on the housing indicates that the switch has tripped – pressing it again restores power.

Construction and additional features

The switch has a sealing lug that allows protection against unauthorized switching on after it has been switched off. Its compact dimensions (diameter 40 mm, height 73 mm) make it easy to install even in tight distribution boxes. The weight of the device is only 0.11 kg, which further simplifies installation. Made of durable materials, it ensures long-lasting and trouble-free operation.

Thanks to its reliability and ease of use, the L-20A overcurrent switch is an ideal solution for both professional installers and end-users looking for effective protection of their electrical installations.
