Cam switch 40A, Disconnector 0-1 (1-pole), in OB13 enclosure. SK40-1.825\OB13

Rotary switch – reliable circuit control

This single-pole rotary switch with a rated current of 40A is a solid solution for frequent switching of electrical circuits. The design with a 0 position and locking in this position provides extra safety and control over the installation. It is ideal for both professional and home installations where reliability and durability are required.

Construction and application

The rotary switch SK40-1.825\OB13 is designed for mounting in OB13 enclosure, which guarantees high protection against external conditions (IP65). Made of durable plastic, it is resistant to mechanical damage and environmental influences. Designed for screw connection of wires, it offers a secure and stable connection. This model, with a knob as the actuating element, enables intuitive operation and precise circuit control.

Key features and benefits

• Durability and reliability: Continuous rated current of 40A and high resistance to atmospheric conditions ensure long-lasting and trouble-free operation.
• Safety: The 0 position with locking minimizes the risk of accidental switching on or off of the circuit during maintenance or repair.
• Versatility: Possibility of use in various electrical installations thanks to universal mounting and a wide range of rated insulation voltages (690 V).
• Protection: IP65 protection class guarantees safe use in environments exposed to moisture and dust.
• Easy installation: Screw connection of wires ensures quick and secure installation by a qualified installer.
• High switching power: Rated operating power for AC-3 is 12 kW at 400 V, allowing control of devices with significant power consumption.
• Durability: Mechanical durability at the level of 3 million switching cycles testifies to the high quality of workmanship and long service life of the device.

Operating parameters

The switch is designed to operate in a wide range of ambient temperatures (-40°C to +70°C), making it suitable for applications both indoors and outdoors. Resistance to vibrations and shocks confirms its reliability in harsh industrial conditions. The cross-section of connection wires is from 4 to 10 mm², and the tightening torque of the terminals is 1.2 Nm – these parameters facilitate correct installation by an electrician.
