Cam switch 40A, Three-phase starter switch (0,Y,A), in OB3 enclosure with lockable front ŁK40-4.831\OB3Z

Motor Starter Switch – Reliability and Safety in One

This three-phase cam switch 40A from SPAMEL is a robust solution for controlling motor starting in a star-delta configuration. Designed for both industrial applications and installations requiring frequent switching, it ensures safe and efficient operation. Made of high-quality plastic and enclosed in a durable OB3 housing with an IP65 protection rating, it guarantees resistance to harsh environmental conditions and long-term operation.

Functionality and Application

The cam switch enables smooth motor starting, reducing inrush currents and minimizing the load on the electrical network. Its intended use in a star-delta configuration makes it ideal for applications requiring gradual increase of the motor torque. The design with a "0" position provides additional safety by allowing complete disconnection of the circuit. Mounting on a rail or directly on a surface allows for flexible adaptation to existing infrastructure.

Key Features and Benefits

• Durable construction: The plastic housing provides resistance to mechanical damage and corrosion.
• High IP65 protection rating: Guarantees protection against dust and water jets, enabling operation in demanding conditions.
• Intended for star-delta configuration: Optimizes the starting of three-phase motors, reducing inrush currents.
• Rated continuous current 40A: Allows handling a wide range of loads.
• Rated operating power 20 kW (at 400V): Allows use in high-power installations.
• Safe to use: Has a "0" position allowing complete disconnection of the circuit.
• Easy installation: Rail or surface mounting options simplify installation.
• Solid screw connections: Ensure stable and reliable connection of wires.
• Resistance to environmental conditions: Operation at temperatures from -40°C to +70°C (storage) and resistance to vibration and shock increase the durability of the device.

The rated continuous current is 40A, and the rated operating power at 400V is 20 kW. The IP protection rating is IP65, it has 3 poles and the connection of the main contacts is realized by screw connections. The housing is made of plastic.

This cam switch is an investment in reliable and safe motor control, which translates into long-term performance and minimizes the risk of failure. Ideal for both professional installers and end-users looking for a solid solution for controlling three-phase motor starting.
