Main Disconnector 25A, front mounting on DIN rail, black enclosed ŁK25RG\S07

Main Disconnector – Reliable Installation Protection

This 25A rated main disconnector is a robust solution for protecting electrical circuits. Designed for both industrial and commercial building applications, it provides effective protection against overloads and short circuits. The design allows for DIN rail mounting, simplifying installation and servicing. The black housing adds to its aesthetic appearance.

Parameters and Application

The disconnector is characterized by high operating parameters, making it suitable for demanding applications. The rated switching power in category AC-3 is 7 kW at 230 V and up to 13 kW at 400 V, allowing it to handle a variety of loads. The continuous rated current (Iu=Ith) is 25A, and the short-circuit strength reaches 1 kA (Icw(1s)) and 13 kA (Icn), ensuring installation safety in the event of a failure. The ability to operate in a wide range of ambient temperatures (-40°C to +70°C) guarantees reliability even in harsh conditions.

The application of the disconnector includes:

• Protecting main circuits in electrical installations.
• Switching circuits on and off during maintenance and repairs.
• Providing safe disconnection of devices from the power supply.
• Installation in electrical distribution boards and control cabinets.

Design and Characteristic Features

The disconnector has been designed with ease of installation and use in mind. The IP65 protection rating provides resistance to dust and water ingress, which is particularly important in industrial environments. The ability to connect cables with a cross-section from 2.5 mm² to 6 mm² provides flexibility when selecting the appropriate cables. Additionally, the disconnector is resistant to vibration and impact, increasing its durability and reliability. The front-sealed design provides additional safety during operation and minimizes the risk of accidental contact with live parts.
