Power disconnect switch LN1, 3-pole 100A LN1-100-I 111995

Power Disconnector – Reliable Installation Protection

The LN1-100-I power disconnector is a key element of any electrical installation, providing safe and efficient circuit disconnection. The device is designed to protect against overload and short circuit in three-phase circuits, and its solid construction guarantees long-lasting and trouble-free operation. It is ideal for both residential and industrial applications.

Functionality and Application

LN1-100-I is a 3-pole disconnector with a rated current of 100A, designed for fixed mounting. It can function as a main, repair, or emergency disconnector. Thanks to the possibility of indirect and plate mounting, it can be easily adapted to different configurations of distribution boards. The use of a lever as an actuating element ensures convenient and intuitive operation. Additionally, the possibility of adding an overcurrent or undervoltage release allows you to tailor the device's characteristics to the specific needs of the installation.

Key Features and Benefits

• Versatility: The ability to use it as a main, repair, or emergency disconnector increases installation flexibility.
• Safety: Provides effective protection against overload and short circuit, protecting devices and infrastructure.
• Durability: Solid construction guarantees reliable operation in harsh conditions.
• Easy Installation: Indirect and plate mounting options make it easy to integrate with existing systems.
• Expandability: The option to add voltage releases allows for precise adjustment of device operating parameters.
• Wide Voltage Range: Rated operating voltage from 690V to 690V ensures compatibility with various power systems.
• Frame Terminals: Allow for easy and secure connection of wires.
• Resistance to External Conditions: IP20 protection degree provides protection against accidental contact and limited ingress of solid objects.

Technical Parameters in Practice

The LN1-100-I disconnector is characterized by a high rated short-time withstand current (Icw) of 2kA and a rated operating power for AC-23 at 400V of 55kW. This means that the device is able to effectively cope with sudden current surges and provide a stable power supply to connected receivers. The rated conditional short-circuit current (Iq) is 100kA, which confirms its ability to protect the installation in the event of serious failures. The device operates in a temperature range from -25°C to +70°C, making it suitable for use in various environments.
