The Siemens 3VA1010-3ED36-0AD0 is a SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous current at 40 °C, with a 3-pole configuration and a TM210 thermal-magnetic release. It carries 75.6 kA breaking capacity at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V — covering the typical fault-current range for industrial distribution panels and motor control centers.
Key ratings & what they mean
The 100 A rated continuous current (Iu) holds through 50 °C; above that it derates to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C — so in a warm enclosure you need to account for the drop. The TM210 release is a fixed thermal-magnetic trip unit, not adjustable for short-time delay, which simplifies coordination but limits selectivity tuning. Breaking capacity spans 75.6 kA at 240 V down to 7.5 kA at 690 V, meaning it can interrupt high fault currents on low-voltage secondary sides but needs upstream current-limiting fuses or a higher-rated MCCB for 690 V systems with high available fault current. Three auxiliary switches (HQ type) are built in — no separate add-on module needed for status feedback to a PLC or remote indication.
Panel fit
Footprint is 76.2 mm wide, 130 mm tall, 70 mm deep — standard for a 3-pole 100 A frame. Front IP40 protection keeps out tools and fingers; the body is not sealed for washdown, so mount it inside a rated enclosure in wet areas.
