Breaking capacity is what sets this frame apart: 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, 52.5 kA at 690 V. That's high-interrupt capability for a 1000 A frame — useful where fault current runs heavy downstream of a large transformer or genset. Power loss at full load runs 332.5 W — that heat has to leave the enclosure; factor it into your thermal budget. The base switch variant is 3VA15105EF320AA0. If your panel spec calls for a different aux configuration or no UVR, this exact order code locks that combination. Dimensions: 320 mm high, 210 mm wide, 120 mm deep. That's a 3-pole frame for 1000 A — expect busbar or cable lugs sized for 2× 300 MCM or equivalent. The 120 mm depth leaves room behind a standard 600 mm deep enclosure for rear-exit connections. No communication function on this variant — it's a straight thermal-magnetic or electronic-trip line-protection breaker, no fieldbus module inside.","metaTitle":"Siemens 3VA1510-5EF32-0CH0 SENTRON MCCB, 1000A, 187kA@240V","metaDescription":"Siemens SENTRON 3VA1510-5EF32-0CH0 molded case circuit breaker, 3-pole, 1000 A rated, 187 kA breaking at 240 V.
