Disconnect switch 40A, Isolator 0-1 (3-pole), base rail mounting front, yellow-grey knob red SK40-2.8211\BS04

Robust Disconnector for Industrial and Domestic Applications

This three-pole cam switch with a rated current of 40A is a reliable solution for safely and conveniently disconnecting electrical circuits. It is suitable for both industrial installations and demanding domestic conditions. The design allows for panel mounting, providing easy access and intuitive operation.

Functionality and Safety

The switch allows switching circuits in the 0-1 position, meaning the power can be completely disconnected. Made of durable plastic, it ensures durability and resistance to mechanical damage. The IP65 protection rating guarantees safe use even in harsh conditions – protecting against moisture and dust. The continuous rated current of 40A and high short-circuit resistance (short-circuit making capacity 0.7kA) provide effective protection of the electrical installation.

Technical Specifications for Professionals

The device is characterized by a rated insulation voltage of 690V and an impulse withstand voltage of 4kV. The rated operating power for AC-3 at 400V is 12kW, making it suitable for applications with medium-power motors. The possibility of connecting wires with a cross-section from 4 to 10 mm² using screw connections ensures easy installation and a secure connection. The switch complies with PN-EN 60947-3 and IEC 60947-3 standards, confirming its high quality and safety.

Mounting and Application

The Spamel SK40-2.8211\BS04 cam switch is designed for indirect mounting on TS35 rail (DIN rail). It is ideal for building electrical switchboards, controllers and other devices requiring reliable circuit disconnection. Thanks to its compact size, it can be easily integrated with existing electrical infrastructure. The red knob provides convenient and intuitive operation, and clear markings facilitate switch position identification.
