Cam switch disconnector 25A, 0-1 (3-pole) with signaling path, in OB2 housing. ŁK25R-2.829\OB2

Robust Disconnect Switch for Industrial Applications

Cam switch 25A, with 0-1 disconnect function and three poles, is a reliable solution for safe and efficient control of electrical circuits. Supplied in a durable OB2 enclosure, it provides protection against environmental influences and mechanical damage. The device is particularly useful in installations requiring frequent load switching, as well as where easy circuit isolation is essential.

Construction and Application

This cam switch is designed for a wide range of applications in industry, construction and automation systems. Its construction based on a cam mechanism guarantees a reliable and stable connection, and the presence of a status indicator allows for quick identification of the switch position. This allows installers to easily diagnose problems and minimize downtime. Designed for mounting on a panel or in a control cabinet.

Key Features and Benefits

• High resistance to environmental conditions: OB2 enclosure protects against dust and moisture (IP65), allowing operation in harsh industrial environments.
• High mechanical durability: Withstands up to 3 million switching cycles, which translates to a long device life and minimizes replacement costs.
• Wide range of voltages and currents: Suitable for operation at a rated insulation voltage of 690V and a rated continuous current of 25A, making it a universal solution for many applications.
• Safety of use: It has high impact resistance parameters (6kV) and short-circuit resistance (13kA), ensuring protection of the electrical installation.
• Status indication: Built-in signaling circuit facilitates monitoring of the switch status, increasing work safety.
• Versatility: Possibility of configuration with a different number of segments (from 1 to 4), adapting the device to specific installation needs.
• Resistance to vibration and shock: Ensures reliable operation even in environments exposed to vibrations and shocks.

User Parameters

The device is characterized by high switching parameters: the rated switching power in category AC-3 is 7 kW at 230V, 13 kW at 400V and 10 kW at 690V. The rated conditional short-circuit current is as high as 13kA, providing effective protection against the effects of short circuits. The tightening torque of the terminals is 1.2 Nm, which facilitates the assembly of wires with a cross-section from 2.5 mm² to 6 mm². The ambient operating temperature is in the range of -40°C to +70°C, allowing it to be used in various climatic conditions.
