What this MCCB is and what it carries
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. Rated insulation voltage is 800 V, and maximum power loss is 25 W.
Panel fit and mounting
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. Front protection is IP40, meaning tools and fingers are kept out but the breaker is not sealed against moisture — suitable for indoor panel mounting, not washdown environments. No undervoltage release, no shunt trip, no communication module, and no ground-fault monitoring on this variant — it is a straight thermal-magnetic line-protection breaker with no accessories built in.
