The Siemens 3VA2110-5MP36-0AA0 is a SENTRON 3VA2 molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C, meaning no derating is needed for panel temperatures up to 70 °C. It carries a 187 kA interrupting capacity at 240 V, dropping to 121 kA at 415 V and 440 V, and 75.6 kA at 500 V — figures that suit high-fault industrial distribution and motor branch circuits.
The 3VA2110-5MP36-0AA0 measures 105 mm wide, 181 mm high, and 86 mm deep — a 3-pole frame that fits standard SENTRON mounting bases and busbar systems in distribution panels. Front-face protection is IP40, adequate for enclosed panel mounting where tools or fingers might contact the front but no washdown exposure is expected. Maximum power dissipation is 10 W, which should be factored into enclosure thermal calculations.
Motor duty and ratings
Rated operating power in AC-3 duty (motor switching) is 30 kW at 230 V. The rated insulation voltage is 800 V, and the storage temperature range spans -40 °C to 80 °C, while operating range is -25 °C to 70 °C. The undervoltage release and ground-fault monitoring are not fitted on this variant; the trip indicator is also absent, so fault status must be read via the communication interface or a separate auxiliary contact.
