Cam switch disconnector 25A, -6.821 in OB3 enclosure with yellow/red lockable cover ŁK25R-6.821\OB3ZC

Cam switch for demanding applications

This 25A cam switch in an OB3 housing is a reliable solution for switching electrical circuits. Designed for both professional and end-user applications, it offers high performance and safety. Equipped with a front cover available in yellow and red, it provides clear identification of the switch status. The OB3 housing construction guarantees durability and resistance to environmental conditions.

Construction and application

The cam switch is designed for frequent switching of AC-3 circuits with a power of up to 13 kW at 400V. Its rotary design provides convenient and precise operation. The housing made of plastic protects against mechanical damage and external factors. The IP65 protection rating guarantees resistance to dust and water jets, allowing for use in harsh industrial conditions. Designed for installation in electrical installations where reliability and safety are required.

Key features and benefits

• High mechanical resistance: Durable plastic construction ensures long-term operation even in demanding conditions.
• Safety of use: IP65 protection protects against moisture and dust, minimizing the risk of short circuits and failures.
• Versatility: Can be used in various types of electrical installations, both in industry and construction.
• Current resistance: Rated continuous current of 25A and high shock current resistance (1kA) allow for safe use with various loads.
• Wide operating temperature range: The ability to operate in a temperature range from -40°C to +70°C ensures reliability even in extreme climatic conditions.
• Easy installation: Screw connection of the main contacts facilitates quick and safe installation of cables with a cross-section from 2.5 mm² to 6 mm².
• Status indication: The front cover in yellow and red colors makes it easy to visually identify the switch status – open/closed.
• Large number of poles: The available 12-pole version allows for the construction of more complex switching systems.

Technical parameters – what you should know

The switch is characterized by a rated operating power of 13 kW for AC-3 at 400 V and a high mechanical durability of 3 million switching cycles. The rated conventional short-circuit current is 13 kA, which provides effective protection of the installation against the effects of short circuits. The housing material – plastic – guarantees electrical insulation and corrosion resistance. It is also important that the device is not intended for indirect mounting or in distribution boards – it is a complete device in a housing ready for use after connecting the cables. The lack of a return to the "0" position means that after changing the position of the knob, the switch remains in the new position until it is manually returned to its original position.
