Above that, it derates: 960 A at 55 °C, 940 A at 60 °C, 920 A at 65 °C, and 900 A at 70 °C. If your panel ambient runs at 60 °C, you lose 60 A of headroom — factor that into your load calculation. ## Physical Fit and Auxiliary Configuration Dimensions are 320 mm high, 210 mm wide, and 120 mm deep. The trip indicator and voltage trigger are present; undervoltage release and ground-fault monitoring are not fitted on this variant. Communication function is not included — this is a standalone line-protection device.","metaTitle":"Siemens 3VA1510-5EF32-0JH0 SENTRON MCCB, 1000 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA1510-5EF32-0JH0 molded case circuit breaker, 1000 A rated at 40 °C, 3-pole, breaking capacity 187 kA at 240 V.
