Cam switch disconnector 40A, 0-1 (3-pole) with signal path, in OB3 enclosure with yellow/red lockable front. ŁK40-2.829\OB3ZC

Cam switch – reliable switching in your installation

This three-pole cam switch with a rated current of 40A is a solid solution for frequent circuit switching. It finds application in both professional installations and in residential construction, where reliability and safety are required. Equipped with a 0-1 disconnector, it allows for easy power disconnection, which is particularly important during maintenance or repair. An additional signaling circuit increases the functionality of the device, informing about its status.

Design and application

The switch is placed in a durable OB3 housing, providing high resistance to mechanical damage and external factors. The front, closed in yellow-red colors, makes it easier to identify the status of the switch (open/closed) and increases safety. Designed to operate in a wide temperature range (from -40°C to +70°C) and characterized by high mechanical durability (3 million switching cycles), it guarantees long-term and trouble-free operation. The possibility of mounting from 1 to 4 segments allows you to adapt the switch to the individual needs of the installation.

Key features and benefits

• High resistance to external conditions: IP41/IP65 protection class provides protection against dust and moisture, allowing the switch to be used even in difficult environmental conditions.
• High durability: 3 million switching cycles guarantee a long service life of the device, minimizing replacement costs.
• Safety of use: Distinct colors of the front (yellow/red) facilitate quick identification of the switch status, which increases work safety.
• Wide range of applications: Rated current of 40A and the possibility of mounting from 1 to 4 segments make the switch universal and can be used in various electrical installations.
• Mechanical strength: Resistance to vibrations and shocks ensures stable operation even in demanding industrial conditions.
• Adapted to different wire cross-sections: The possibility of connecting wires with a cross-section from 4 to 10 mm² provides installation flexibility.
• Compliance with standards: Meets the requirements of IEC standards, which confirms its quality and safety of use.

The rated insulation voltage is 690 V, and the rated impulse withstand voltage is 6 kV. The rated continuous current is 40 A, and the rated switching power in category AC-3 at 400V is 20 kW. The rated short-time withstand current is 0.85 kA, and the permissible wire cross-section is from 4 to 10 mm².
