The 100 A continuous rating at 40 °C holds flat up to 50 °C; above that it derates to 98 A at 55 °C and 91 A at 70 °C. The rated insulation voltage is 800 V, so the breaker is also suitable for 690 V systems with the appropriate interrupting rating (11.9 kA at 690 V). Interrupting ratings step down across the voltage table: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at 500 V and 690 V. The 3-pole footprint (76.2 mm wide, 130 mm tall, 70 mm deep) fits standard Siemens SENTRON mounting bases and busbar kits. The undervoltage release coil draws power from the control circuit; ensure the upstream control transformer or power supply is sized for the inrush. Auxiliary switch wiring (two form-C contacts plus one trip-alarm contact) terminates on the breaker's integral terminal block — no add-on module required.","metaTitle":"Siemens 3VA1110-3EF32-0DH0 SENTRON MCCB, 100 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1110-3EF32-0DH0 molded case circuit breaker, 100 A at 40 °C, 3-pole, 75.6 kA at 240 V.
