Cam switch 40A, Disconnector 0-1 (2-pole), panel mounting front grey knob black SK40-1.828\P03

Cam switch for panel mounting – reliable circuit switching

This 2-pole cam switch, with a rated current of 40A, is a robust solution for disconnecting and connecting electrical circuits. Designed for panel mounting, with a grey face and black knob, it combines functionality with aesthetics. The device is characterized by a high degree of protection IP65, which guarantees safety in demanding environmental conditions.

Construction and application

The SK40-1.828\P03 switch is a modular element designed for building switchboards and controls. Its cam mechanism-based design ensures reliable and dependable circuit switching. It finds application in industrial installations, workshops, and anywhere requiring frequent and safe disconnection of devices. The possibility of indirect mounting increases installation flexibility.

Key features and benefits

• Durability and safety: IP65 protection rating protects against dust and water ingress, ensuring safe operation in harsh conditions.
• Suitable for high loads: Rated continuous current of 40A and the ability to operate with a load of up to 12 kW (AC-3) allow for use in demanding applications.
• Universal mounting: Indirect mounting option simplifies integration with various structures.
• Clear indication: Distinct marking of the 0-1 positions ensures easy identification of the switch status.
• Solid construction: Made of plastic, resistant to mechanical damage and chemical factors.
• Safe operation: Lack of auxiliary contacts eliminates the risk of accidental short circuits or unwanted operations.
• Wide voltage range: Suitable for operation in networks with a voltage of up to 690V.

Technical parameters in practice

The rated switching power for AC-3 is 12 kW at 400V – this means that the switch can easily handle motors with a power of up to approximately 15 kW (depending on the power factor). The rated short-circuit current Icm at 1.5 kA provides protection against the effects of short circuits in the installation. The housing material – plastic – guarantees good electrical insulation and corrosion resistance. The inability to return to the "0" position means that after switching off, the switch remains in the off position, which increases operating safety.
