Cam switch disconnector 40A, Isolator 0-1 (3-pole) with signaling path, in OB2 enclosure. SK40-2.829\OB2

Cam switch – reliable switching in harsh conditions

This three-pole cam switch with a rated current of 40A, with 0-1 disconnecting function and a signaling path, is a solid solution for frequent circuit switching. It finds application in both industrial installations and commercial construction. The OB2 housing provides high mechanical resistance and protection against external factors.

Design and parameters

The switch is designed to operate in a wide temperature range – from -40°C to +70°C – making it an ideal choice for outdoor and demanding environmental applications. Mechanical endurance of 3 million switching cycles guarantees long-lasting and trouble-free operation. Wires with a cross-section of 4…10 mm² can be easily and safely connected thanks to the tightening torque of the terminals of 2.0 Nm. Protection class IP41 (with respect to the panel) and IP65 provides protection against contact and ingress of solids and water.

Applications and benefits

• Versatility: Suitable for AC-3 circuits (motors) and AC-4 (operation with high starting torques).
• Safety: Rated switching power up to 20 kW (400 V) ensures safe switching of the load.
• Durability: Made of high-quality materials, resistant to vibration, shock and humid heat.
• Signaling: Built-in signaling path allows monitoring of the switch status.
• Protection: Short-time withstand current Icw (1s) is 0.85 kA, and the rated short-circuit making current Icm is 1.5 kA – this provides additional protection for the installation.
• Mounting: Compact design facilitates mounting in tight spaces.

The Spamel SK40-2.829\OB2 cam switch is an investment in the reliability and safety of your electrical installation. It is a product tested by professionals and meeting stringent quality standards.
