Disconnect switch 20A, 0-1 switch (3-pole), panel mount, yellow-grey knob, red SK20-2.8211\P04

Universal cam switch for safe circuit switching

This three-pole cam switch SK20-2.8211/P04 from SPAMEL is a reliable solution for manual switching of electrical circuits. Designed for both professional and home use, it provides safe and convenient operation. Made of high-quality plastic, it is resistant to mechanical damage and ensures long-lasting operation. Designed for surface mounting (front panel), it offers easy access and intuitive operation.

Functionality and application

The cam switch allows you to choose between two positions: 0 (off) and 1 (on). Its design allows you to disconnect the circuit in the "0" position, which increases safety during maintenance or repair. The rated continuous current of 20A and the ability to operate with a load of up to 4kW (AC-3, 400V) make it ideal for controlling various types of electrical devices, such as motors, heaters or lighting. The IP65 protection class guarantees resistance to dust and water jets, allowing it to be used in harsh environmental conditions.

Construction and characteristic features

Equipped with a screw connection of the main contacts, it ensures a secure and durable connection of the wires. The yellow-gray housing with a red knob makes it easy to identify and operate. The possibility of indirect mounting expands the range of applications of the switch. The lack of auxiliary contacts makes it a simple and economical solution for basic switching applications. The design with the "0" position allows for complete disconnection of the circuit, which increases safety during maintenance or repair work. In addition, the high quality of workmanship guarantees reliability and long service life – confirmed by mechanical endurance at the level of 3 million switching cycles.
