That range suits loads with moderate inrush — motor starters, small transformers, lighting banks — where a B curve would nuisance-trip on startup surge but a D curve would delay too long for conductor protection.","metaTitle":"ABB S403M-C63 S400 MCB, 3P, 63A, Curve C, 10kA","metaDescription":"ABB S403M-C63 S400 series 3-pole MCB, 63 A, Trip Curve C, 240 VAC, 10 kA interrupting rating.
