Cam switch disconnector 40A, Isolator 0-1 (3-pole) with signaling path, in OB2 enclosure. ŁK40-2.829\OB2

Cam switch – reliable disconnection in the installation

This three-pole cam switch with a rated current of 40A is a solid solution for safely disconnecting electrical circuits. Equipped with a 0-1 disconnecting mechanism, it enables quick and reliable switching between the "0" (off) and "1" (on) positions. The design with a signaling path further increases functionality, allowing for visual control of the circuit status. The whole is enclosed in a durable OB2 housing, providing adequate protection against external factors.

Construction and application

The Spamel ŁK40-2.829\OB2 cam switch is designed for use in industrial and construction electrical installations. It will be useful wherever reliable disconnection of circuits is required, e.g. when servicing machines, maintaining equipment or in automation systems. The solid construction and high resistance to environmental conditions guarantee long-term and trouble-free operation. Designed for conductors with a cross-section of 4-10 mm², which provides a wide range of applications in various installations.
