Industrial GL Type Isolator Switch – Heavy-Duty Power Isolation for Medium-to-Large Industrial Applications.

The Industrial GL Type Isolator Switch is a high-performance power disconnector engineered for safe and reliable electrical isolation in demanding industrial, commercial, and infrastructure installations. With a 160A rating, this switch is ideally suited for larger machinery, sub-distribution boards, and critical equipment requiring robust disconnection capabilities.
Key Features:
Optimized 160A Rating: Part of the 20-3200A family, the 160A model delivers the perfect balance of capacity and compactness for medium-to-large industrial loads, compressors, and manufacturing lines.
Flexible Pole Configurations: Choose between 3P (three-pole) for standard three-phase loads or 4P (four-pole) for systems requiring neutral disconnection, ensuring compliance with various earthing systems (TN, TT, IT).
Wide Operating Temperature: Efficiently operates within -5°C to +40°C ambient conditions, suitable for diverse climates and unheated industrial facilities.
Clear ON/OFF Indication: Features a visible contact position indicator, confirming safe isolation status for maintenance personnel and supporting lockout/tagout (LOTO) procedures.
Applications:
Distribution board incomers for commercial buildings
HVAC systems and large compressor units
Renewable energy systems (commercial solar installations)
Emergency stop disconnection points for critical equipment
