Cam switch 40A, 1-0-2 switch (3-pole), in OB13 enclosure. SK40-3.8380\OB13

Universal Cam Switch – Reliability and Functionality

This three-pole cam switch, with a rated current of 40A, is a robust solution for safe and efficient switching of electrical circuits. The 1-0-2 design allows you to choose between two different power sources or disconnect the circuit, making it ideal for backup power systems, power distribution boards, or applications requiring frequent load switching. Manufactured by the renowned Spamel, it guarantees high quality and long-lasting reliability.

Construction and Application

The switch is housed in a durable OB13 enclosure, providing protection against external conditions (IP65 protection). This makes the device perfect for use in both dry and humid or dusty environments. Cable connection is made via screw connections, ensuring a secure and stable electrical connection. Designed for mounting on a panel or in a distribution box (although not intended for this purpose), it offers flexibility in installation. This model is particularly useful where manual circuit switching is required – e.g., in workshops, laboratories, or when operating machines and equipment.
