GL Series 160A 3P/4P Safety Disconnect Switch | Compact Load Isolator

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
