Industrial Applications

1. Short-Circuit Protection for Small-Scale Industrial Water Pumps

In industrial wastewater treatment systems, small 3-phase centrifugal pumps rated at 0.75 kW (400V) are heavily used and prone to sudden blockages or electrical short-circuits. The GV2L07 provides dedicated magnetic protection, ensuring that in the event of a high-current fault, the system is isolated instantly within milliseconds.

Problem Solved

Prevents upstream power bus collapses and catastrophic stator coil damage by offering a massive 100 kA breaking capacity to interrupt high-fault short circuits immediately without damaging auxiliary controls.

2. High-Interruption Protection for HVAC Ventilation Fans

Commercial HVAC ventilation fan motors (rated around 0.75 kW to 1.1 kW at 400-500V AC) operating in dense industrial distribution panels require high-fault current coordination. The GV2L07's magnetic-only trip unit reacts to short-circuit currents at 33.5 A (13 times the nominal 2.5 A rating) to safeguard the motor feeders.

Problem Solved

Eliminates nuisance tripping during normal motor starting currents while providing instant high-speed magnetic disconnection during line-to-line or line-to-ground faults in multi-fan ventilation networks.

3. Feeder Circuit Protection in Machinery Conveyor Lines

In manufacturing assembly lines, small conveyor belts powered by fractional horsepower motors (1.5 kW at 690 V AC) are managed by centralized motor control centers (MCC). Using the GV2L07 on the 690 V branch ensures dedicated, localized short-circuit protection conforming to IEC 60947-2 standards.

Problem Solved

Avoids widespread factory-floor shutdowns by isolating localized short-circuits on individual conveyor lanes, exploiting the unit's 4 kA breaking capacity at 690 V and allowing the rest of the MCC to continue operating safely.
