Cam switch 16A, Disconnector 0-1 (3-pole) with signal track, in OB2 housing with yellow/red front. ŁK16R-2.829\OB2C

Cam switch – reliable switching in electrical installations

This 16A cam switch with 0-1 disconnecting switch (3-pole) is a robust solution for controlling electrical circuits. Equipped with a signaling contact and housed in a durable OB2 enclosure with a yellow-red front, it provides both safety and clear identification of the switching status. The product is designed for use in low-voltage installations where reliability and frequent switching are required.

Construction and application

Cam switches, such as this model, are used to mechanically connect and disconnect electrical circuits. They are ideal as switches, disconnectors, changeover switches and control switches in electrical installation enclosures. The segmented design with double cams allows for the creation of custom connection programs tailored to specific application needs. The knob rotation angle can be 30°, 45° or 90°, providing high configuration flexibility. This particular model (3-pole) is especially useful in applications requiring simultaneous disconnection of all phases.

Key features and benefits

• Durability and reliability: Designed to operate in harsh environmental conditions, from -40°C to +70°C, meets the requirements of PN-EN60947-3 and IEC 60947-3.
• Safety: OB2 enclosure provides protection against external factors (IP65), and the clear front marking (yellow-red) facilitates quick identification of the switch status.
• Versatility: Possibility of configuring the connection program thanks to the segmented design and different knob rotation angles.
• Resistance to external factors: Exhibits resistance to vibrations, shocks, damp heat and salt mist – confirmed by appropriate IEC standards.
• Adaptation to various applications: Suitable for mounting on a panel, base, rail or directly in the enclosure (OB1, OB2, OB3, OB4).
• High mechanical durability: Provides up to 3 million switching cycles – a guarantee of long-term operation.
• Rated switching power: Has a rated switching power of up to 8 kW at 400V (AC-4).

Technical parameters – what you should know

The switch is characterized by a continuous rated current of 16A and a conventional rated short-circuit current of 13kA. The short-time withstand current is 0.9kA and the short-circuit making capacity is 1.3kA. The cross-section of the connection cables is 1.5…4 mm², and the tightening torque of the terminals is 1.2 Nm. It is worth paying attention to the presence of a signaling contact – it facilitates monitoring of the switch status and increases the safety of the installation. The IP65 degree of protection guarantees protection against dust and water jets.
