Power disconnect switch LN1 4-pole 100A LN1-4-100-I 111999

Power disconnect switch – reliable installation protection

The LN1-4-100-I power disconnect switch from Eaton is a four-pole device designed to safely disconnect electrical circuits. It provides effective protection against overload and short circuit, and also allows manual disconnection of the power supply for maintenance or repair work. The device's design allows for mounting on a rail or directly on a plate, increasing its versatility.

Functionality and application

This disconnect switch is ideal for use in electrical installations of commercial and industrial buildings, as well as in energy distribution boards. Its high rated continuous current value (100A) and short-circuit withstand capacity (2kA) guarantee reliable operation even in demanding conditions. The possibility of mounting a motor drive (optional) further increases user comfort, especially in the case of large-sized switchboards. The device can function as a main, maintenance or emergency disconnect switch, offering versatile use in various installation configurations.

Construction features and parameters

The LN1-4-100-I disconnect switch is characterized by a solid construction and high quality workmanship. Made of durable materials, it ensures long-lasting and trouble-free operation. Frame terminals facilitate the connection of wires with a cross-section from 2.5 mm² to 16 mm² (solid wire) or 25 mm² to 70 mm² (stranded wire). The locking mechanism prevents accidental opening of the circuit during operation, increasing safety. The IP20 degree of protection provides protection against contact with fingers and solid objects. The device is designed to operate at temperatures from -25°C to +70°C. The rated operating voltage is 690 V AC, and the maximum operating voltage is 400 V AC. Additionally, the disconnect switch has an optional voltage release for increased functionality of the protection system. The ability to rotate by 90° in all directions makes it easier to install in tight spaces.
