Mounts in any position. The fastening method is the quick assembly system typical of SENTRON MCBs — clips onto the DIN rail without tools. ## Environmental and derating considerations Ambient temperature range is -40 °C to 75 °C, but the continuous current rating must be derated above 55 °C: the breaker is rated for max 95 % humidity at 55 °C, 55 % at 70 °C, and 35 % at 75 °C. In a hot panel, the 32 A nominal rating may need to be reduced — the C-curve thermal element responds to ambient temperature, so a 32 A breaker in a 70 °C enclosure may trip below 32 A on a sustained load. Vibration resistance per IEC 60068-2-6 is ±1 mm displacement at 5 to 25 Hz and 50 m/s² acceleration at 25 to 150 Hz — adequate for installation on machinery or in enclosures subject to typical industrial vibration, but not rated for continuous high-amplitude vibration near rotating equipment without additional support.","metaTitle":"Siemens 5SY5232-7CC SENTRON MCB, 32A C-Curve, 2-Pole DC, 10k","metaDescription":"Siemens 5SY5232-7CC SENTRON miniature circuit breaker, 32A, C-curve, 2-pole, 440V DC, 10kA breaking capacity per IEC 60947-2.

It also carries a 15 kA DC breaking capacity per IEC 60947-2 versus the 10 kA on the 5SY5232-7CC, so it offers higher fault-current headroom if the panel SCCR allows it. The 5SY5240-7 is also AC/DC rated, while the 5SY5232-7CC is DC-only. Both share the same mechanical dimensions and mounting, so a swap requires no panel rework."},{"question":"How do I get pricing and availability for 5SY5232-7CC?","answer":"Submit an RFQ through this listing.
