Cam switch 16A, 1-0-2 switch (3-pole), in OB3 enclosure. ŁK16R-3.8380\OB3

Rotary switch – reliable circuit switching

This three-pole rotary switch with a rated current of 16A is a solid solution for frequent switching of electrical circuits. Equipped with a "0" position, it allows for safe disconnection of the power supply, which is crucial during maintenance or repairs. The OB3 enclosure design provides high resistance to external conditions and mechanical damage, which translates to long life and trouble-free operation.

Design and application

The switch is designed for surface mounting, and its screw connections guarantee a secure and durable connection of the wires. The housing material – plastic – provides insulation and safety of use. The IP65 protection class protects against dust and water ingress, making it ideal for use in harsh industrial conditions or outdoors. This model is a switch with a knob, which makes it easy to operate even with gloves on.

Key features and benefits

• Durability and reliability: Continuous rated current of 16A and high mechanical resistance (3 million switching cycles) guarantee long-term use without frequent replacement.
• Safety: The "0" position allows for complete disconnection of the circuit, minimizing the risk of electric shock during maintenance work. IP65 protection class protects against environmental influences.
• Versatility: Rated operating power for AC-3 is 8 kW at 400V, allowing for use in various electrical installations.
• Easy installation: Screw connections ensure quick and secure wiring.
• Resistance to external conditions: Wide operating temperature range (-40°C to +70°C) and resistance to vibration and impact make the switch suitable even in demanding industrial conditions.
• Application in harsh conditions: Resistance to cyclic salt spray confirms the possibility of use in corrosive environments.

Operating parameters

The rated short-circuit current withstood by the switch is 0.9 kA (for 1 second), and the short-circuit switching current is 1.3 kA. The cross-section of the connection wires should be from 1.5 mm² to 4 mm², and the tightening torque of the terminals is 1.2 Nm. The rated insulation voltage U_i is 690 V, and the rated impulse withstand voltage U_imp is 6 kV.
