Disconnect switch 15A, Disconnector 0-1 (3-pole), in OB3 enclosure. ŁK15-2.8211\OB3

Rotary switch – reliable switching in electrical installations

This three-pole rotary switch with a rated current of 15A is a versatile device designed for switching electrical circuits on and off. It finds application in both industrial installations and residential construction, where manual control over power supply is required. Thanks to its solid construction and high IP65 protection class, it ensures safe and long-lasting operation even in harsh conditions.

Construction and application

A rotary switch is a multi-way rotary switch that allows you to control currents in low-voltage circuits. This model is supplied in a durable OB3 housing, which provides protection against external factors and mechanical damage. The housing made of plastic guarantees good insulation and corrosion resistance. Equipped with a knob, it enables intuitive operation and precise switching of circuits. The 0 position allows for complete disconnection of the power supply, which increases safety during maintenance or repairs.

Key features and benefits

• High reliability: Construction based on proven solutions and solid materials ensure long-lasting and trouble-free operation.
• Versatility: Can be used in various types of electrical installations – industrial and construction.
• Safety: IP65 protection class protects against dust and water, increasing safety when used in harsh conditions.
• Intuitive operation: The knob allows for easy and precise switching of circuits.
• 0 position: Provides complete disconnection of the power supply for increased safety during maintenance or repair work.
• Rated AC-3 operating power: 8 kW – allows you to control loads with significant power.
• Mechanical strength: Made of high-quality materials, resistant to mechanical damage.
• Easy installation: Screw connection of the main contacts facilitates quick and safe installation.

Technical parameters and compliance with standards

The switch meets the requirements of PN-EN 60947-3 and IEC 60947-3 standards, confirming its compliance with European safety standards. Designed to operate at temperatures from -25°C to +70°C (when using an appropriate housing with an IP65 degree of protection). The rated continuous current is 15A, and the maximum power for AC-3 at 400V is 8kW. The lack of normally open, normally closed and changeover auxiliary contacts simplifies the design and increases the reliability of the device. The OB3 housing provides an IP65 degree of protection, guaranteeing resistance to dust and water ingress.
