Cam switch disconnector 25A, isolator 0-1 (6-pole), in OB13 enclosure with yellow/red lockable front SK25-3.8210\OB13ZC

Rotary switch – reliable circuit control

This six-pole rotary switch with a rated current of 25A is a robust solution for controlling electrical circuits. Equipped with a 0 position, it provides safe and convenient disconnection of power. The housing in OB13 ensures high resistance to external conditions and mechanical damage, and the front with yellow and red colors facilitates visual identification of the device status.

Construction and application

The rotary switch SK25-3.8210\OB13ZC is complete, supplied already in the housing, which simplifies installation and saves time. It is designed for applications requiring frequent switching of circuits, e.g. in motor control systems, lighting or heating devices. The cam mechanism ensures smooth and precise change of position, and screw connections guarantee reliable and durable connections of wires with a cross-section of 4…10 mm². The IP65 protection class protects against moisture and dust, allowing operation in harsh industrial conditions.

Key features and benefits

• Durability and reliability: The housing made of plastic and high quality workmanship ensure long life of the device even with intensive use.
• Safety: The 0 position allows complete disconnection of the circuit, which increases safety during maintenance or repair.
• Versatility: The possibility of mounting up to 4 segments allows adaptation of the switch to different installation configurations.
• Resistance to external conditions: IP65 protection class provides protection against dust and water stream, allowing the switch to be used in harsh environmental conditions.
• High rated power: The rated power for AC-3 is 8 kW at 400V, allowing control of devices with significant power.
• Simple installation: The complete device in the housing facilitates and speeds up installation.
• Mechanical durability: The switch withstands as many as 3 million switching cycles, guaranteeing long-term use without the need for replacement.

User parameters

The switch is characterized by a rated continuous current Iu at the level of 25A and a conventional rated short-circuit current of 10kA. It withstands a short-time withstand current Icw(1s) of 0.5kA and a peak withstand current Icm at the level of 0.7kA. The ambient operating temperature is in the range of -40°C to +70°C, and the storage temperature is also from -40°C to +70°C. Vibration resistance (IEC 60068-2-6) is ±1mm amplitude displacement or ±0.7g amplitude acceleration in the frequency range of 2-13Hz and 2-100Hz. It also exhibits shock resistance (IEC 60068-2-27) of 15g with an impulse duration of 11ms.
