What this MCCB delivers on the line
The 3VA1010-3ED32-0AH0: Three-pole construction, line protection version. No undervoltage release, no ground-fault module, no communication — this is a straightforward thermal-magnetic MCCB for standard distribution and feeder protection.
Breaking capacity — what the numbers mean for your fault duty
Rated breaking capacity of 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V. These are the maximum fault currents this MCCB can safely interrupt at each voltage level. For a 480 V panel, the 32 kA figure at 440 V is the closest benchmark — make sure your available fault current stays under that threshold.
Current derating — don't let the 100 A sticker fool you
Rated 100 A at 40 °C, 45 °C, and 50 °C. Derating starts at 55 °C (96 A), then 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. If this breaker lives in a hot panel — near a drive, transformer, or in a sun-baked enclosure — you lose 10 A by the time ambient hits 70 °C. Size your load accordingly. The TM210 release is adjustable for the long-time pickup (Ir), letting you dial in the protection curve for the actual cable or busbar ampacity.
Panel fit and auxiliary contacts
Dimensions: 130 mm height, 76.2 mm width, 70 mm depth. Drops into the same cutout as other 3VA 100 A frames. Comes with 2 auxiliary switches + 1 trip alarm switch (HQ version). That gives you two form-C contacts for status feedback plus a dedicated alarm contact that changes state only on a trip — useful for remote fault annunciation without wiring through the aux contacts. Front face rated IP40 — fine for a clean indoor panel. No IP rating on the body, so keep it inside the enclosure.
Lifecycle and sourcing reality
Marked as current production. No phase-out notice, no last-time-buy window. This is a standard Siemens catalog MCCB you can order today and expect to get for the next several years.
