Cam switch disconnector 40A, 0-1 switch (4-pole), in OB13 housing with yellow/red lockable front SK40-2.8210\OB13ZC

Universal cam switch – reliable circuit switching

This four-pole cam switch with a rated current of 40A is a robust solution for switching electrical circuits. Made of durable plastic, enclosed in an OB13 housing with a yellow-red front, it provides both safety and ease of use. Designed to operate at a rated insulation voltage of 690V, it can also withstand impulse voltages up to 4kV.

Design and application

The switch is designed for frequent circuit switching, offering a "0" position for complete isolation. Its screw connection-based construction guarantees secure and durable wire connections from 4 to 10 mm². Thanks to the IP65 protection rating (front side), it is resistant to dust and water ingress, making it ideal for use in harsh environmental conditions. It is not intended for mounting in distribution boards or indirect mounting – it is a complete device in a housing, ready for immediate use.

Key features and benefits

• High reliability: Rated continuous current of 40A and short-circuit current of 10kA ensure safe and stable operation in demanding applications.
• Versatility: Can be used in various electrical installations thanks to a wide range of rated voltages and switching power (up to 12kW at AC-3, 400V).
• Durability: The housing material – plastic – and high-quality workmanship guarantee a long service life (3 million switching cycles).
• Safety: IP65 protection rating protects against external factors, minimizing the risk of failure and ensuring safe operation.
• Easy installation: Complete device in a housing simplifies installation and reduces the time required to start up the system.
• Mechanical strength: Resistance to vibration and shock (compliant with IEC 60068-2-6 and IEC 60068-2-27 standards) ensures stable operation even in harsh industrial conditions.
• Wide operating temperature range: The ability to operate in a temperature range from -40°C to +70°C makes it suitable for both indoor and outdoor applications.

This cam switch is an optimal choice for both professionals installing electrical systems and end-users looking for a reliable solution for switching circuits. Its solid construction, high-quality workmanship and wide range of applications guarantee long-lasting and trouble-free use.
