Cam switch 100A, three-phase starter switch (0,Y,A), in OB18 enclosure with yellow/red lockable front. SK100-4.831\OB18ZC

Three-phase starter switch – reliable motor control

This three-phase cam switch with a rated current of 100A is a robust solution for controlling electric motors. Designed for operation in 0-Y-Δ (star-delta) circuits, it enables smooth starting and reversing. Manufactured by the renowned SPAMEL, it combines high-quality workmanship and durability, translating into trouble-free operation in demanding industrial conditions. The OB18 enclosure with a lockable yellow-red front provides safety and clear identification of the switch status.

Construction and application

The SK100-4.831\OB18 cam switch is a modular device used for starting three-phase motors, switching resistive loads, and in reversing circuits. Thanks to the possibility of configuration with a different number of segments (up to 7), it can be adapted to individual application needs. The use of a knob as the actuating element guarantees convenient and precise operation. The solid construction and high degree of protection IP65 (front part) make the device resistant to harsh environmental conditions such as dust and moisture.
