Load Break Switch (LBS) Panels

Specification
Load Break Switch (LBS) Panels are designed for safe switching and isolation of electrical circuits in medium voltage (MV) networks ranging from 3.3 kV to 33 kV. These panels are primarily used in power distribution networks, ring main units (RMU), and transformer protection applications to ensure efficient load management and fault isolation..

Working & Operation

• Switching & Isolation: The Load Break Switch (LBS) allows switching of electrical loads under normal operating conditions.

• Fault Protection: Provides isolation during faults, preventing damage to electrical equipment.

• Arc Extinction Mechanism: Uses SF6 gas or air insulation to safely interrupt the current flow and minimize arc formation.

• Integration with Ring Main Units (RMU): Often used in ring main systems for compact and reliable power distribution.

Salient Features 

• Voltage Rating: 3.3 kV, 6.6 kV, 11 kV, 22 kV, 33 kV

• Current Rating: Up to 1250A

• Short Circuit Withstand Capacity: Up to 25kA for 1 sec

• Switching Mechanism: Manually operated, motorized, or automatic

• Insulation Type: Air Insulated (AIS) or SF6 Gas Insulated (GIS)

• Protection Class: IP42, IP54, or IP55 (Indoor/Outdoor applications)

• Compact & Modular Design: Easy to install and integrate with existing switchgear

• Reliable Fault Isolation: Ensures minimal downtime and enhanced system protection

Applications

• Power Generation Plants

• Industrial Facilities

• Commercial Complexes
