The interrupting rating is the headline: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V. At 415 V the 121 kA still covers most industrial service entrances. The steep drop to 7.5 kA at 500 V and 690 V means this breaker is not intended for 690 V motor circuits with high fault potential; for those, a higher-voltage-rated frame would be needed. Three-pole design, 76.2 mm wide (3 in), 130 mm tall (5.12 in), 70 mm deep (2.76 in). Fits standard Siemens SENTRON panelboard and MCCB mounting bases. The 3-pole footprint is the same as other 100 A SENTRON frames, so a swap-in replacement for an existing 3VA1 breaker requires no bus-bar rework. The 800 V rating also means it's suitable for 690 V systems where the interrupting rating (7.5 kA) is adequate. Maximum power loss 27.5 W at rated current — this is the heat the breaker dissipates into the enclosure. For a panel with multiple breakers, this figure drives ventilation or derating calculations. At 100 A, 27.5 W is typical for a 3-pole MCCB of this class. The storage range exceeds operating — that's the handling limit, not the running limit. The breaker can be stored in unheated warehouses across most climates.","metaTitle":"Siemens 3VA1110-5MH32-0DH0 SENTRON MCCB, 100 A, 3-Pole, 187","metaDescription":"Siemens 3VA1110-5MH32-0DH0 SENTRON molded case circuit breaker, 100 A at 40 °C, 3-pole, 187 kA interrupting at 240 V.
