LMGL-T Transparent Load Isolation Switch 3P 4P 63‑630A
LMGL-T Transparent Load Isolation Switch 3P 4P 63‑630A
LMGL-T series transparent load isolation switch is a cabinet‑mount manual load‑break disconnect switch for low‑voltage power distribution. Available in 3‑pole and 4‑pole versions with rated current from 63A up to 630A. Its unique transparent flame‑retardant housing lets operators visually check contact open‑close status without disassembling the unit. Built‑in robust copper busbars guarantee low contact resistance and excellent overload resistance. Widely integrated inside power distribution cabinets, generator cabinets, photovoltaic combiner boxes and industrial main power switchgear. Supports bulk order, technical customization and project‑oriented solution for power contractors and system integrators.

Product Overview
Key Product Features
✅ Visible Transparent Flame‑Retardant Housing
High‑strength transparent anti‑burn plastic shell. Operators can directly observe contact closing / opening status. No cabinet disassembly required for quick status check, effectively prevent hidden safety hazards caused by contact adhesion.
✅ Heavy‑Duty Thick Copper Conductive System
Adopt high‑purity thick copper contacts and busbars. Low contact resistance, stable conductivity, outstanding overload and short‑time withstand current performance. Reduce heat generation under long‑time full‑load operation.
✅ Reliable Manual Mechanical Interlock Structure
Front‑of‑cabinet long handle operation. Clear O‑I marking. Precise mechanical interlock prevents mis‑switching. Smooth switching action even under heavy‑current working conditions.
✅ Wide‑range Current & Pole Options
Complete specification range: 3P / 4P poles; rated current 63A,100A,160A,250A,400A,630A. Cover small commercial cabinet to heavy‑duty industrial power‑house projects.
✅ Easy Cabinet Installation & Compatibility
Standard cabinet mounting dimensions. Fits most common low‑voltage power cabinet, generator control cabinet. Direct mechanical front‑handle operation, no complex auxiliary wiring needed.
✅ Broad Application Compatibility
Suitable for AC 400V low‑voltage system. Works for grid‑generator switching, photovoltaic power distribution, factory main power isolation, commercial building power switchgear.
