Cam switch 100A, Disconnector 1-0-2 (4-pole), in OB18 housing with yellow/red front SK100-4.8396\OB18C

Universal Rotary Disconnector 100A – Reliability and Flexibility

This rotary disconnector, with a rated current of 100A and a 1-0-2 configuration (4 poles), is a solid solution for both professional installers and end-users. Designed for safe and efficient circuit switching, it finds application in a wide range of electrical installations – from industrial to commercial and domestic. Manufactured by the renowned Spamel, it guarantees high quality workmanship and compliance with applicable standards.

Construction and Application

The rotary switch SK100-4.8396\OB18C (in OB18 housing with a yellow/red front plate) allows convenient switching between three positions: 1, 0 and 2. This functionality makes it ideal for applications requiring frequent load switching, e.g. in motor control systems, direction of rotation switches or power distribution boards. The construction with double cams allows for the creation of individual connection programs, tailored to the specific needs of the installation. Thanks to the possibility of mounting in a housing, the device is protected from external factors and ensures safe operation in various environmental conditions. The IP65 protection class guarantees resistance to dust and water jets.
