Cam switch connector 25A, 1-0-2 switch (3-pole), long black knob SK25-3.8380\P09

Cam switch – reliable switching in electrical installations

This three-pole cam switch with a rated current of 25A is a solid solution for disconnecting electrical circuits. The 1-0-2 design allows you to choose between three positions: connection, disconnection and connection of two poles. Manufactured by Spamel, a manufacturer with an established position on the market, it ensures long-lasting and safe operation. The long black knob makes it easy to operate, even in difficult conditions.

Construction and application

The switch is designed for mounting in an OB2 enclosure, which provides high resistance to external factors, including dust and moisture (IP65). The wide range of applications includes both industrial and building installations where reliable and frequent circuit switching is required. It can be used in motor control, lighting and other electrical devices. Thanks to its solid construction and high technical parameters, the switch performs perfectly in demanding applications.

Key parameters and features

This switch stands out with its high electrical parameters – the continuous rated current is 25A, and the rated insulation voltage is 690V. This ensures safe use in high-voltage installations and resistance to overvoltage thanks to the impulse withstand voltage of 6kV. The rated switching power in category AC-3 is 7 kW at 230V, 13 kW at 400V and 10 kW at 690V, respectively, allowing control of various loads. High short-circuit resistance is guaranteed by the conventional rated short-circuit current of 13kA.

The enclosure with a protection degree of IP65 protects against dust and water jets, and the wide operating temperature range from -40°C to +70°C allows the switch to be used in harsh environmental conditions. It is adapted for wires with a cross-section from 2.5 mm² to 6 mm², and the tightening torque of the terminals is 1.2 Nm, ensuring a stable connection. Additionally, high mechanical durability (3 million switching cycles) guarantees long-term trouble-free operation.

The switch is also characterized by high mechanical durability (3 million switching cycles), which guarantees long-term trouble-free operation. Made of high-quality materials, it provides resistance to mechanical damage and corrosion. Mounting in an OB2 enclosure provides additional protection against external factors, which is particularly important in harsh industrial conditions.
