Cam switch disconnector 40A, 1-0-2 switch (3-pole), base mounting rail front locking black SK40-3.8380\BS07

Universal cam switch for safe circuit switching

This three-pole cam switch with a rated current of 40A is a reliable solution for manual switching of electrical circuits. The 1-0-2 design allows you to choose between two power sources or completely disconnect the load, making it ideal for use in workshops, construction machinery, and installations where quick and safe disconnection of power is required. Rail mounting allows for easy integration with existing electrical infrastructure.

Construction and application

The switch is designed for durability and safety. The housing made of durable plastic provides resistance to mechanical damage and environmental influences. The IP65 protection class guarantees protection against dust and water jets, allowing operation in harsh conditions. The lockable front (P07/P08 version) further increases safety, preventing unauthorized access and accidental circuit switching. Designed for indirect mounting, it offers flexibility in choosing the installation location.

Key features and benefits

• High reliability: Continuous rated current of 40A and short-circuit current of 10kA ensure safe operation even under heavy loads.
• Versatility: The ability to choose between two power sources (1-0-2) or completely disconnect the circuit increases the functionality of the device.
• Safety: IP65 protection protects against dust and water, and the ability to lock prevents unauthorized access.
• Durability: Made of high-quality plastic guarantees long device life.
• Easy installation: Designed for rail mounting, which simplifies and speeds up installation.
• Wide range of applications: Ideal for workshops, construction machinery, industrial installations and anywhere manual switching of electrical circuits is required.
• High switching power: Rated switching power up to 12 kW for AC-3 supports a variety of devices and loads.
• Resistance to external conditions: Wide operating temperature range (-40°C to +70°C) allows use in harsh environmental conditions.

Additional information: the switch has 3 poles, and its housing material is high-quality plastic providing insulation and resistance to mechanical damage. The switch has characteristics allowing for frequent switching operations (3 million cycles).
