SENTRON 3VA1110-5EE32-0DA0 — 100 A MCCB with TM220 Release and Undervoltage Trip
The Siemens 3VA1110-5EE32-0DA0 is a 3-pole SENTRON molded case circuit breaker rated for line-protection duty, carrying a continuous current of 100 A at 40 °C through 50 °C before the thermal derating curve begins to pull it back — 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. That derating profile means the breaker holds its full rating across typical panel ambient conditions; you only lose headroom above 50 °C, which is useful to know when the breaker shares an enclosure with heat-generating contactors or drives. Breaking capacity is specified across five voltage points: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V.
Undervoltage Release and Auxiliary Release Design
The trip indicator is not present on this order code, so there is no local mechanical flag showing the trip cause; you'd rely on the UVR's own status or a remote auxiliary contact if added.
The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a 3-pole footprint that fits standard SENTRON 3VA mounting bases and busbar systems. The 76.2 mm width (3 inches) is the critical dimension for multi-pole grouping in a distribution panel; three of these side-by-side occupy 228.6 mm of DIN-rail or panel-mounting width. Depth of 70 mm (2.76 in) leaves clearance for rear-connected busbars or cable lugs without protruding past the enclosure depth limit.
