Power disconnect switch LN1, 3-pole 160A LN1-160-I 111997

Power Disconnector – Reliable Power Disconnection

The LN1-160-I power disconnector is a three-pole device designed for the safe disconnection of electrical circuits. It finds application in both industrial installations and public buildings, where reliability and high resistance to working conditions are required. The device's construction allows for permanent mounting, and its compact dimensions facilitate integration with existing switchboards.

Features and Application

This device functions as a main and repair disconnector, allowing for safe power disconnection during maintenance or repair work. Thanks to the possibility of indirect and plate mounting, the LN1-160-I disconnector is flexible in application and adapts to different installation configurations. The rated continuous current of 160A and high short-circuit strength (up to 2kA) guarantee effective protection of the circuit against overloads and short circuits. Additionally, the optional overvoltage release increases the functionality of the device, allowing adaptation of the protection parameters to specific installation needs.

• Versatility: Can function as a main or repair disconnector.
• Safety: Provides effective protection against overload and short circuit – like any circuit breaker in this class.
• Mounting Flexibility: Possibility of indirect mounting, on a plate or in switchboards.
• High Resistance: Adapted to work in difficult conditions thanks to a wide range of operating temperatures (-25°C to +70°C).
• Compatibility: Works with a wide range of accessories from the LZM/LN and NZM/N series, such as remote drives, releases and auxiliary contacts.
• Durability: Designed for long-term operation with a high number of switching cycles (mechanical and electrical).

Construction and Parameters

The LN1-160-I disconnector is characterized by a solid construction using high-quality materials. It has frame terminals providing a secure connection of wires. It is equipped with a lever as an actuating element and a locking mechanism for increased safety. The device meets the standards IEC/EN 60947-3 and VDE 0660, confirming its compliance with applicable safety standards. The rated operating voltage is 690V AC, and the rated operating power for AC-23 at 400V is 90kW. The IP20 degree of protection provides protection against accidental contact.
