1-pole 100 A MCCB with TM210 release
The Siemens 3VA1110-5ED12-0AA0 is a 1-pole SENTRON molded case circuit breaker rated for 100 A continuous current at 40 °C through 50 °C, with no derating needed across that range. Above 50 °C, the ampacity steps down: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C — plan your enclosure thermal budget accordingly. TM210 release provides LI protection with fixed instantaneous pickup of 1,000 A. Breaking capacity hits 121 kA at 240 V AC and 9 kA at 415 V AC; the 240 V figure covers most North American panelboard applications, while the 415 V rating suits IEC 60947-2 installations at common European distribution voltages. Rated insulation voltage Ui is 500 V, and maximum DC operational voltage is 125 V — usable in DC branch circuits within that limit.
Mounts on standard DIN rail; the 25.4 mm width (1 inch) per pole means a single-pole unit occupies one module slot, stacking neatly alongside other 1-pole SENTRON breakers in a distribution board. Depth of 70 mm and height of 130 mm fit within typical enclosures.
