Rotary switch 20A, 1-0-2 isolator (4-pole), front panel mounting yellow-grey knob red SK20-4.8396\P24

Cam switch – reliable circuit switching

This four-pole cam switch, with a rated current of 20A, is a solid solution for frequent switching of electrical circuits. The design with a "0" position provides additional safety and convenience, allowing for complete disconnection of the circuit. It is ideal for applications requiring manual control, both in industrial installations and in residential buildings.

Construction and application

The switch is designed for front panel mounting. Made of durable plastic, it provides good insulation and resistance to mechanical damage. The use of screw connections guarantees secure and durable wire connections. The yellow-gray housing with a red knob makes identification and operation easier. The IP65 protection class means resistance to dust and water jets, allowing operation in harsh environmental conditions.

Key features and benefits

• Versatility: Possibility of indirect mounting expands the range of applications for the switch.
• Safety: The "0" position allows for complete disconnection of the circuit, minimizing the risk of short circuit or electric shock.
• Durability: Made of high-quality materials ensures a long service life – mechanical endurance is as much as 3 million switching cycles.
• Resistance: IP65 protection class protects against external factors such as dust and water.
• Efficiency: Rated operating power for AC-3 is 4 kW at 400V, allowing to operate various receivers.
• Practical solution: The knob makes operation easier even with gloves or in difficult working conditions.
• Universality: Suitable for installation in various environments – from workshops to residential buildings.

Technical parameters in practice

The rated continuous current of 20A allows for safe power supply of most standard electrical devices. The switch is adapted to work at a rated insulation voltage of 690V and withstands impulse voltages up to 4kV. Adapted for wires with a cross-section of 1...4 mm², which provides flexibility when choosing the appropriate cables. It is worth noting the high resistance to vibrations and shocks – the switch has been tested in accordance with IEC 60068-2-6 and IEC 60068-2-27 standards, which confirms its reliability in harsh industrial conditions.
