Cam switch disconnector 40A, Isolator 0-1 (4-pole), in OB2 enclosure with yellow/red lockable front ŁK40-2.8210\OB2ZC

Universal cam switch for demanding applications

This four-pole cam switch with a rated current of 40A is a robust solution for switching electrical circuits. Equipped with a 0-1 disconnector, it provides safe and reliable power disconnection. The OB2 housing, made of durable plastic, guarantees resistance to mechanical damage and external factors. The yellow-red front cover facilitates identification and signaling of the switch status.

Design and application

The switch is designed for use in both industrial installations and commercial construction. Its rotary design provides convenient and precise operation. Screw connection of the main contacts guarantees a secure and durable connection of wires with a cross-section of 4…10 mm². The rated operating power for AC-3 is 20 kW at 400 V, making it suitable for controlling motors and other high-power devices. The IP65 protection class on the front side provides protection against dust and water jets, allowing installation in harsh environmental conditions.

Key features and benefits

• High reliability: Rated continuous current of 40A and short-circuit withstand current of 0.85 kA ensure safe operation even in loaded circuits.
• Versatility: The possibility of use in installations with a rated insulation voltage of up to 690 V and a wide operating temperature range (-40°C to +70°C) make the switch compatible with various electrical systems.
• Safety: The plastic housing protects against electric shock, and the IP65 protection class protects against external factors.
• Durability: Mechanical durability of 3 million switching cycles guarantees a long service life.
• Easy installation: The design adapted for indirect mounting (although not required) and clear markings facilitate installation and servicing.
• Status indication: The colored front (yellow-red) allows for quick visual identification of the switch status.
• Application: Ideal for switching circuits powering machines, heating devices or industrial lighting - everywhere where a reliable circuit change or power disconnection is required.
