Cam switch disconnector 25A, 0-1 switch (4-pole), in OB2 housing with yellow/red lockable front plate ŁK25-2.8210\OB2ZC

Cam switch – reliable circuit switching

This four-pole cam switch 25A, in OB2 housing with a lockable front (yellow-red), is a robust solution for mechanically switching electrical circuits on and off. The device is designed to implement specific connection programs, depending on the knob position. It will be useful in both industrial installations and public buildings where reliability and safety are required.

Construction and application

The SPAMEL ŁK25R-2.8210\OB2ZC cam switch is designed for mounting in electrical installation enclosures. Its construction provides protection against external factors (IP65 protection class), which guarantees long-term and trouble-free operation even in difficult conditions. It is used where manual circuit switching is needed, e.g. when changing the power source, servicing equipment or in control systems. Designed to operate with a rated insulation voltage of 690V and an impulse withstand voltage of 6kV.

Key features and parameters

• Rated continuous current: 25A – ensures safe operation for devices with appropriate power consumption.
• Rated switching power: 7 kW (230 V), 13 kW (400 V), 10 kW (690 V) – allows connection of devices with different power depending on the supply voltage.
• Mechanical endurance: 3 million switching cycles – guarantees long device life even with intensive use.
• Wide operating temperature range: -40°C to +70°C – allows the switch to be used in various environmental conditions.
• Protection class IP65: Provides protection against water jets and dust, increasing safety in harsh industrial conditions.
• Connection cable cross-section: 2.5...6 mm² – allows connection of cables of different thicknesses, adapting to the needs of the installation.
• Tightening torque of clamps: 1.2 Nm - ensures a secure connection of the cables and minimizes the risk of loosening connections during operation.
• Rated conditional short-circuit current: 13 kA - an important parameter for ensuring the safety of the installation in the event of a short circuit.

Thanks to its solid construction and high technical parameters, the SPAMEL cam switch is an investment in a safe and reliable electrical installation.
