That deliberate delay is sized for loads with high starting surges — think small motors, solenoid banks, or DC power-supply input capacitors. On a pump or compressor start, the D-curve lets the inrush pass without nuisance tripping, whereas a B- or C-curve would clear too fast and drop the line. The trade-off: arc-fault protection is less sensitive, so verify the downstream wiring is rated for the let-through energy. ## Panel fit and wiring constraints The 76 mm depth fits flush with most standard distribution boards.","metaTitle":"Siemens 5SY4232-8CC SENTRON MCB, 2P 32A D-Curve, 10kA","metaDescription":"Siemens SENTRON 5SY4232-8CC miniature circuit breaker, 2-pole 32A D-curve, 10kA IEC breaking capacity.
