The Siemens SENTRON 3VA1110-5ED32-0AB0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current at 40 °C, with a TM210 thermal-magnetic overcurrent release. The interrupting ratings are the headline: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. The TM210 release gives you a fixed thermal pickup and adjustable magnetic trip — set the magnetic threshold to coordinate with downstream branch breakers. Temperature derating is baked in: the breaker carries 100 A up to 50 °C, then steps down to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C.
The 76.2 mm width (3 inches) is standard for a 3-pole MCCB in the 100 A frame size, so it fits existing SENTRON 3VA panel cutouts and busbar systems. Mounting is via screw-clamp to a backplate or DIN rail adapter (not included). The IP40 front means it's fine in a NEMA 1 or 12 enclosure; no gasketing needed on the front face.
