Cam switch 100A, three-phase starter switch (0,Y,A), base rail mounting front grey black knob SK100-4.831\BS03

Cam switch for reliable load switching

This three-phase cam switch with a rated current of 100A is a robust solution for safe and efficient switching of electrical circuits. Designed for installation in distribution boards or directly on busbars, it ensures reliable operation in demanding industrial and commercial environments. The design with a black knob and gray housing makes it easy to operate and identify in the system.

Functionality and application

The cam switch SK100-4.831\BS03 allows manual switching of circuits, which is particularly useful during maintenance, repairs or power failures. Thanks to the ability to set to the "0" position, it provides additional safety when working on the electrical installation. The switch is used in motor starters, changing the direction of rotation, and in power distribution systems where manual control over current flow is required. Made of durable plastic, it guarantees long-lasting and trouble-free operation.

Key features and benefits

• High resistance to external conditions: IP65 protection class protects against dust and water jets, allowing the switch to be used in harsh environmental conditions.
• High rated power: Rated power of 25 kW at 400 V allows operation of even demanding loads.
• Safety of use: It has a "0" position, which ensures disconnection of the circuit during maintenance or repair work.
• Solid construction: Made of high-quality plastic, resistant to mechanical damage and corrosion.
• Easy installation: Designed for mounting on busbars, which simplifies and speeds up installation.
• Versatility: Suitable for a wide range of applications – from simple electrical installations to advanced control systems.
• Adapted for frequent switching: Mechanical endurance of 3 million switching cycles guarantees long life even with intensive use.
• Safety confirmed by certificates: It has the CE marking, which proves compliance with European safety standards.

Technical parameters in practice

Rated continuous current of 100A means that the switch can safely operate with a load of this intensity for a long time without the risk of overheating or damage. The ability to operate at 690V ensures compatibility with various power systems. Screw connection of the main contacts guarantees a secure and durable connection of the wires, minimizing the risk of short circuit or loss of contact. The design adapted for indirect mounting provides flexibility in choosing the installation location.
