Cam switch disconnector 63A, 1-0-2 switch (3-pole), base mounting rail front locking black SK63-3.8380\BS07

Cam switch – reliable circuit switching

This 3-pole cam switch SK63-3.8380\BS07 is a robust solution for frequent switching of electrical circuits. Designed for both industrial and construction applications, it provides safe and convenient operation. A key-lockable design (black finish) increases security and minimizes the risk of accidental setting changes. DIN rail mounting simplifies installation and integration with existing systems.

Construction and application

The SK63 cam switch is a device used for manual switching of electrical circuits. This model, designated 1-0-2, allows you to choose between three positions: off (0), and two different circuits (1 and 2). It is ideal where it is required to disconnect the load or switch the power between different receivers - e.g. in switchboards, control cabinets or with machines and equipment. The plastic construction provides good electrical insulation and resistance to mechanical damage. The IP65 protection class guarantees protection against dust and water jets, allowing it to be used in harsh environmental conditions.

Key features and benefits

• Durability and reliability: Continuous rated current of 63A and high mechanical resistance (3 million switching cycles) ensure long-lasting and trouble-free operation.
• Safety: Key-lockable design minimizes the risk of accidental setting changes, especially important in industrial applications.
• Versatility: DIN rail (TS35) mounting allows for easy installation in various switchboard and control cabinet configurations.
• Resistance to external conditions: IP65 protection protects against dust and water, enabling operation in harsh environmental conditions.
• Wide voltage range: Rated insulation voltage of 690V allows the switch to be used in installations with different voltages.
• High switching power: Rated switching power up to 18 kW at 400V (AC-3) allows operation of even demanding receivers.
• Adapted to work in difficult conditions: Wide operating temperature range (-40°C to +70°C) allows operation in extreme climatic conditions.
• Easy operation: The knob provides convenient and intuitive circuit switching.

Technical parameters in practice

This switch not only meets safety standards (IP65), but also offers practical solutions for installers. Screw connection of the main contacts ensures a secure connection of wires with a cross-section from 6 to 16 mm². The switching angle of 30°-45°-90° provides flexibility during installation and adaptation to specific application needs. In addition, high short-circuit strength (Icw(1s) = 1.2 kA) increases the safety of the installation in the event of a short circuit. It is worth noting the protection class II, which provides additional protection against electric shock.
