The 2-pole construction switches both phase conductors; neutral is not switched, which is the standard arrangement for single-phase or two-phase loads where the neutral is bonded elsewhere. That's high enough for most industrial distribution boards fed by a transformer of several hundred kVA. The DC rating of 15 kA at 60 V (max 72 V) covers battery banks, UPS outputs, and DC bus applications — but note the voltage ceiling: 60 V rated, 72 V maximum operating, so it fits 48 V nominal systems with float voltage up to 60 V, not 110 V DC traction batteries. Ambient range from -40 °C to 75 °C, with derating for humidity: max 95% RH at 55 °C, dropping to 35% at 75 °C. That covers outdoor cabinets in cold climates and warm indoor switchgear rooms.","metaTitle":"Siemens SENTRON 5SY8215-8 2P MCB, D-curve, 70 kA IEC, 5 kA U","metaDescription":"Siemens SENTRON 5SY8215-8 miniature circuit breaker, 2-pole, D tripping characteristic, 70 kA breaking capacity per IEC 60947-2, 5 kA per UL 1077.
