Cam switch disconnector 63A, Isolator 0-1 (4-pole), in OB2 enclosure with lockable front ŁK63-2.8210\OB2Z

Cam switch – reliable switching in electrical installations

This four-pole 63A cam switch with 0-1 disconnecting function is a robust solution for switching electrical circuits on and off. It finds application in both industrial installations and commercial and residential construction, where reliability and safety are required. The product is supplied in a durable OB2 housing with a lockable front, which provides protection against moisture and external interference (IP65 protection class).

Construction and application

Spamel cam switches are universal elements of low-voltage electrical installations. They serve as switches, disconnectors, changeover switches and control switches. The construction with double cams allows for the creation of various connection programs, tailored to the specific needs of the application. This model, with the 0 position, allows for safe isolation of the circuit during maintenance or repair. Made of plastic, it is lightweight and easy to install. Designed to operate in a wide temperature range (from -40°C to +70°C), it will perform well even in harsh environmental conditions.

Key features and benefits

• High mechanical and chemical resistance: The housing made of high-quality plastic ensures durability and resistance to damage.
• Safety of use: IP65 protection class guarantees protection against moisture and dust, minimizing the risk of short circuits and failures.
• Versatility: The ability to configure the connection program thanks to the double cams allows you to adapt the switch to different applications.
• Easy installation: Screw connection of the main contacts facilitates and speeds up installation.
• High rated power: The rated power for AC-3 is 20 kW at 400 V, which allows you to operate demanding loads.
• Compliance with standards: The product meets the requirements of PN-EN60947-3 and IEC 60947-3 standards, which confirms its safety and reliability.
• Wide operating temperature range: Enables use in various environmental conditions (-40°C to +70°C).

Technical parameters in practice

The rated continuous current of 63A allows for safe loading of the circuit. The use of a screw connection ensures a secure and durable connection of the wires. This makes the switch perfect for electrical installations requiring high reliability and safety. The segmented construction allows for flexible adaptation to the needs of a specific installation – it can be configured in terms of the number of poles and switching functions. In addition, high mechanical strength (3 million switching cycles) guarantees a long service life even with intensive use.
