Cam switch 40A, Disconnector 0-1 (3-pole), \P05 ŁK40-2.8211\P05

Cam switch – reliable connection and disconnection of circuits

This three-pole cam switch with a rated current of 40A is a solid solution for low-voltage electrical installations. Designed for both industrial and residential applications, it provides safe and efficient circuit control. The switch design allows for multiple on/off operations, making it an ideal choice for applications requiring frequent switching.

Construction and application

The Spamel SK40-2.8211\OB13Z (or LK40-2.8211\P05) cam switch is an element designed for mounting on a panel or in an enclosure. A wide operating temperature range (-40°C to +70°C) enables its use in harsh environmental conditions. Thanks to the IP65 protection rating (front part), it is resistant to dust and water ingress, which increases its durability and reliability. It can be used as a switch, disconnector, changeover switch or control switch in electrical circuits. The segmented structure with double cams allows for the creation of individual connection programs, tailored to the specific needs of the installation.
