Scope of Application

The ETGL (HGL) series load break switch-disconnector is a new generation of load disconnect switches developed by our company. Featuring a dual-break, dual-arc-extinguishing-chamber design, they offer high switching capacity, a compact structure, and convenient installation and wiring; they represent the next generation of low-voltage load break switch-disconnector. The ETGL (HGL) series is suitable for 50 Hz AC systems with a rated insulation voltage of 800 V, a rated operating voltage of 400 V, and a rated current up to 3200 A. It is primarily used in power distribution or motor circuits for infrequent switching and isolation of circuits and lines. The product complies with standards GB/T 14048.1 and GB/T 14048.3.

Normal operating conditions

• Ambient Temperature: The upper limit shall not exceed +40° C, the lower limit shall not be less than -5° C, and the average temperature over 24 hours shall not exceed +35° C.
• Altitude: The installation site must be at an altitude of no more than 2,000 m.
• Ambient Conditions: Max. 50% RH at +40 ° C; higher RH allowed at lower temps (e.g., 90% at 20° C). Special measures required for occasional condensation due to temp variations.
• Pollution Level: Level 3
• Installation Requirements: The basic installation requirement for ETGL (HGL) products is vertical installation.

Product Features

• High current capacity, compact size, long creepage distance, and long electrical life;
• Featuring a dual-break, dual-arc-extinguishing-chamber design, it offers high switching capacity and a long isolation distance;

• Features a viewing window that directly displays the open/closed status of the contacts;

• Spring-loaded operating mechanism; no manual operation required; moving and stationary contacts can achieve rapid make and break;

• Compact design, easy wiring, safe and reliable, saving time and effort;
• Available in three-pole and four-pole conffgurations, with options for in-cabinet or out-of-cabinet operation.
