Load break switch LBS

Introduction

ETI product serie

The LBS series offers a comprehensive range of Load Break Switches, specifically engineered to ensure safe and reliable disconnection under load conditions. Designed for use across a variety of low-voltage electrical installations, these switches support a wide range of current ratings and application requirements, from industrial control panels to commercial distribution boards. Their robust construction, compact design, and easy mounting make them ideal for both new installations and retrofit projects, ensuring maximum flexibility and operational safety.

The LBS series covers a wide range of current ratings, from 160A to 3200A, making it suitable for a broad spectrum of applications—from small-scale commercial systems to large industrial installations. This flexibility allows users to select the appropriate switch for their specific load requirements, ensuring reliable performance, optimal safety, and efficient energy management across various operating conditions

LBS Series Variants:

• LBS: The standard LBS series offers robust performance for various applications.
• LBSCD: The LBSCD series is designed for applications with reduced short circuit current capability. It offers a cost-effective solution for specific requirements.

Application

Key Features of Load Break Switches:

• Make and break under load conditions: LBS switches are specifically designed to interrupt current flow while the circuit is carrying a load. This capability distinguishes them from disconnectors, which are only intended to be operated in a no-load condition.
• Safety isolation: LBS switches provide a visible break in the circuit, ensuring that the isolated equipment is completely de-energized. This visual isolation enhances safety during maintenance or repair work.
• Manual operation: LBS switches are typically operated manually using a handle, providing direct control over the circuit's status.
• Durable construction: LBS switches are built with robust materials to withstand harsh environments and frequent operations. The use of glass fibre reinforced polyester provides high mechanical and temperature resistance for the LBS enclosure.
• Compliance with standards: LBS switches are designed, qualified, and tested according to international standards, such as IEC 60947-3. This ensures their safety and reliability.
