100 A MCCB with flat derating and high interrupting capacity
The Siemens 3VA2010-5HN36-0CH0 is a SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous current, holding that rating flat from 40 °C through 70 °C ambient — no derating curve to calculate for typical panel environments. Three poles, line protection design, with a maximum power loss of 16 W. Breaking capacity reaches 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V — figures that cover most industrial distribution fault levels without requiring a current-limiting upstream device.
Built-in auxiliary switches and undervoltage release
Factory-fitted with 2 auxiliary switches plus 1 trip alarm switch (HQ configuration), and an undervoltage release (UVR) — no separate accessory ordering or field assembly needed for basic status feedback and UV protection. The UVR drops the breaker on loss of control voltage, standard for motor feeder and safety circuits. Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a 3-pole frame that fits standard SENTRON panel cutouts and busbar arrangements. Operating temperature range -25 °C to 70 °C; storage -40 °C to 80 °C.
