The Siemens SENTRON 3VA1110-5EE36-0AA0 is a 3-pole molded case circuit breaker rated for line protection, carrying a TM220 thermal-magnetic trip unit and a continuous current of 100 A at 40 °C ambient. Its interrupting capacity is voltage-dependent: 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 — so the available fault current at the panelboard determines which voltage column governs the selection. Thermal derating is minimal through 50 °C (still 100 A), then drops to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C — useful when the breaker sits in a warm enclosure or next to other heat sources. The TM220 trip unit is a fixed thermal-magnetic design — no interchangeable rating plugs, so the 100 A frame is the trip rating you get.
Dimensions are 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON distribution panels and switchboards without re-drilling the mounting plate.
