1. Short-Circuit Protection in Multi-Motor Control Panels (MCCs)
The GV2L20 acts as the dedicated magnetic short-circuit protective component in a three-component starter system (combining a GV2L20 breaker, an LC1D contactor, and a TeSys LRD thermal overload relay) for conveyor or high-inertia industrial motors.
Problem SolvedStandard combined thermal-magnetic breakers can undergo nuisance trips during high-inertia motor startups. Utilizing the magnetic-only GV2L20 separates thermal and magnetic curves, allowing engineers to configure a custom Class 20 thermal overload relay for slow starts while keeping robust, high-speed magnetic trip protection up to 50 kA.

2. Dedicated Magnetic Fault Isolation for Water Submersible Pumps
Installed inside centralized outdoor pump control panels, the GV2L20 protects 3-phase submersible pump motors rated up to 7.5 kW at 400/415 V. It provides instantaneous isolating action during terminal or winding short-circuits.
Problem SolvedDeep-well pumps experience severe inductive inrush currents that can degrade standard miniature circuit breakers over time. The GV2L20's high 223 A magnetic trip point prevents nuisance tripping during starting phases, while its IP20-rated, DIN-rail friendly housing easily integrates into industrial pump enclosures.

3. HVAC Ventilation Fan Motor Protection in Industrial Facilities
Protects industrial ventilation fan motor arrays against massive fault currents up to 50 kA at 400/415 V AC. Maintained inside the plant's main control cabinet, it offers simple local diagnostic capability via its manual rotary toggle.
Problem SolvedUnlike conventional fuses which require manual replacement and stocking of spares after a fault, the GV2L20 features a rotary handle that visually communicates a tripped state. Maintenance teams can diagnose the fault, resolve the physical issue, and reset the motor line immediately without system downtime.
