Cam switch 15A, Three-phase starter switch (0,Y,A), in OB2 enclosure. ŁK15-4.831\OB2

Three-phase starter switch – reliable motor control

This three-phase cam switch, catalog number ŁK15-4.831\OB2, is a robust solution for controlling electric motors. Designed for both professional and end-user applications, it provides safe and efficient circuit switching. Made in a durable OB2 housing, it guarantees long-lasting and reliable operation in various conditions. The switch allows for 0-Y-∆ configuration, making it a versatile tool in electrical installations.

Construction and application

A cam switch is a device used for manual switching of electrical circuits. In this model, we have a three-pole design, which means the ability to control three phases simultaneously. The application of this type of switch is wide – from simple applications in workshops to more complex systems in industry. Thanks to the possibility of changing the configuration (0-Y-∆), it is ideal for starting three-phase motors, allowing to limit the starting current and protect the installation. The OB2 housing provides high resistance to mechanical damage and external factors.

Key features and benefits

• High resistance to external conditions: IP65 protection rating guarantees protection against dust and water jets, allowing the switch to be used even in harsh environmental conditions.
• Durable construction: Made of plastic ensures lightness and corrosion resistance.
• Safety of use: Rated operating power for AC-3 is 8 kW at 400 V, and rated continuous current is 15 A – these parameters ensure safe operation of the device in typical applications.
• Versatility: The ability to configure 0-Y-∆ makes the switch compatible with various types of three-phase motors.
• Easy installation: Screw connection of the main contacts facilitates connection of wires and ensures a secure electrical connection.
• Mechanical durability: The switch withstands up to 3 million switching cycles, guaranteeing long-term trouble-free operation.
• Suitable for operation in a wide temperature range: The device can operate at temperatures from -25°C to +70°C, making it suitable for indoor and outdoor applications (with appropriate protection).

Additional information: the switch has a "0" position, which increases safety and allows for complete disconnection of the circuit. Lack of auxiliary contacts (normally open and normally closed) simplifies the construction and reduces the cost of the device without affecting its basic functionality.
