Fuji air switch leakage circuit breaker EW250EAG-3P

The EW250EAG-3P is the upgraded replacement model of Fuji’s old EG series ELCBs, optimized in arc extinguishing, leakage detection and shell corrosion resistance. Unlike single fixed-sensitivity low-end breakers, the multi-gear adjustable leakage circuit of EW250EAG-3P solves the universal industry pain point: low mA sensitivity causes frequent false tripping of large motors, while high mA fails to protect staff electric shock risk. Users switch gears via internal dial without replacing separate breakers, greatly reducing cabinet spare parts inventory cost. Built-in high-speed zero-sequence current transformer precisely captures tiny ground leakage signals; electromagnetic trip mechanism realizes rapid circuit cut within 0.1s under 30mA shock protection mode to guarantee operator safety. Independent arc extinguishing grid absorbs high-temperature arc generated during short-circuit tripping, avoiding internal component burnout of EW250EAG-3P and extending service life in heavy-load industrial distribution. Flame-retardant V0 grade plastic shell resists dust, oil mist and mild moisture corrosion, suitable for machining, chemical and wastewater workshop power distribution environments. Standardized mounting size achieves direct one-to-one replacement of old EG203 series breakers without modifying cabinet hole layout, shortening equipment renovation construction cycle. All test data of EW250EAG-3P meets global mainstream electrical certification standards, applicable to export machinery and overseas factory power projects.
