Cam switch 100A, three-phase starter switch (0,Y,A), panel mounting front grey knob black SK100-4.831\P03

Universal cam switch for disconnecting and switching circuits

This three-pole cam switch SK100-4.831\P03 from SPAMEL is a reliable device designed for safely disconnecting and switching electrical circuits. It is suitable for both industrial installations and public buildings where high reliability and frequent switching of loads are required. The design allows for mounting on a panel, providing convenience and ease of operation.

Construction and application

The SK100 cam switch allows for the implementation of various connection programs thanks to its segmented construction with double cams. It can be used to switch off motors (AC3), connect resistive loads, switch the direction of rotation of three-phase motors, and as a starting element (star-delta). The construction made of plastic provides good electrical insulation and resistance to mechanical damage. The black knob makes operation and identification of the switch position easier. The IP65 protection class guarantees protection against dust and water jets, allowing operation in harsh environmental conditions.

Key features and benefits

• High reliability: The design based on proven SPAMEL solutions ensures long-lasting and trouble-free operation.
• Versatility: The ability to configure the connection program allows the switch to be adapted to different applications.
• Safety: The IP65 protection class protects against external factors, and the solid construction ensures safe use.
• Easy installation: Designed for panel mounting, which facilitates installation and maintenance.
• Suitable for working with high currents: The rated continuous current of 100A allows use in circuits with high loads.
• Mechanical durability: Designed for a large number of switching cycles (3 million).
• Wide voltage range: Possibility of operation at a rated insulation voltage of 690V.
• With 0 position: Has a clearly marked "0" position, ensuring safe disconnection of the circuit.

Technical parameters in practice

The rated operating power for AC-3 at 400V is 25 kW, which means that the switch can effectively cooperate with motors of this power. The rated continuous current at 100A ensures stable operation even under heavy load. The use of screw connections of the main contacts guarantees a secure and durable connection of the wires. The lack of normally open or normally closed auxiliary contacts simplifies the design and reduces the cost of the device, while fulfilling the basic functions of disconnecting and switching circuits. The housing material - plastic - provides good electrical insulation and resistance to mechanical damage and chemical factors.
