Cam switch disconnector 40A, Isolator 0-1 (3-pole) with signaling path, in OB2 enclosure with yellow/red lockable front ŁK40-2.829\OB2ZC

Cam switch – reliable disconnection in the installation

This three-pole cam switch with a rated current of 40A is a robust solution for safely disconnecting electrical circuits. The 0-1 disconnector design allows easy switching between off and on modes, which is particularly useful during maintenance, repairs or failures. An additional signaling circuit increases safety by informing about the current circuit status.

Solid construction and high resistance

The switch enclosed in a durable OB2 housing provides high protection against external factors. The front panel locked in yellow-red colors facilitates quick identification of the device status – red indicates off, and yellow indicates readiness for operation. The housing meets IP41 standard, and in some configurations even IP65, which guarantees protection against touch and ingress of solids. The device is resistant to vibrations, shocks and humid environments, making it suitable even in harsh industrial conditions.

Parameters tailored to demanding applications

The switch is designed to operate with a rated insulation voltage of 690V and withstands impulse voltages of 6kV. The continuous rated current is 40A, and the rated switching power in AC-3 category is 20kW at 400V. The use of characteristic C ensures that the device copes well with impulse loads, such as starting electric motors. Connection cables with a cross-section from 4 to 10 mm² can be firmly tightened with a torque of 2.0 Nm, ensuring a stable connection. Mechanical durability at the level of 3 million switching cycles guarantees long and trouble-free operation of the device.
