Industrial Applications

1. Overload Protection for Small Centrifugal Pumps

In water treatment or chemical dosing systems, small centrifugal pumps driven by compact 3-phase fractional horsepower motors (e.g., 0.12 kW or 0.18 kW) must be protected against dry running or mechanical blockages, which cause excessive current draw [1.1.5]. The GV2P04 offers a precise adjustable range from 0.4A to 0.63A, allowing engineers to calibrate thermal protection precisely to the pump motor's full load current.

Problem Solved

Prevents sustained overload conditions and winding failure caused by mechanical blockages or impeller jams, ensuring the pump system does not suffer catastrophic motor burnout.

2. Short-Circuit and Overload Defense for Conveyor Motors

In automated packaging lines, small conveyor belts are powered by low-wattage gearmotors. Frequent starting and potential material jams can stress the motor. The GV2P04 provides 100 kA short-circuit breaking capacity and precise thermal-magnetic tripping, safeguarding these fractional kilowatt motors from overcurrent damage during a mechanical jam.

Problem Solved

Protects low-power conveyor drive motors from thermal degradation during mechanical overload (jams) and limits high fault currents in milliseconds, preventing damage to the upstream distribution block.

3. Reliable Motor Protection for Exhaust and Ventilation Fans

Industrial cabinets and HVAC systems often utilize low-power 3-phase exhaust fans running continuously at 400/415 V. The GV2P04 motor circuit breaker serves as both the local manual disconnect switch and the main protection device. Its IP20 design ensures safety in control panels, while its class 10 thermal trip characteristics protect the fan motor from single-phasing or stator overheating.

Problem Solved

Ensures local manual isolation during fan maintenance and prevents continuous operation under single-phasing conditions which would otherwise burn out the stator windings of the exhaust fan.
