What this MCCB does for your panel
The Siemens SENTRON 3VA2010-5KP32-0AG0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full operating temperature range — 40 °C through 70 °C — so no derating curve to chase when the panel runs hot near motor starters or drives. Its interrupting capacity hits 187 kA at 240 V and still holds 121 kA at 415 V, which means it can sit upstream of a high-fault bus without needing a current-limiting fuse ahead of it. The breaker is designed for line protection — feeder duty — and carries a built-in communication function plus an other measurement function, so it can report status and load data back to a controller without an add-on module. Rated insulation voltage is 800 V, and the maximum power loss at rated current is 13.5 W — worth checking against your enclosure's thermal budget if you're packing several breakers in a small panel.
Panel fit and integration
The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep — standard MCCB footprint for a 3-pole 100 A frame, so it drops into existing SENTRON or third-party mounting plates without re-drilling. It ships with one auxiliary switch and one trip alarm switch (HP type) pre-installed, giving you a closed-contact signal for PLC input without wiring extra limit switches. The trip indicator is visible through the front cover, so a field tech can tell at a glance whether the breaker tripped on overcurrent or was manually opened.
Breaking capacity by voltage level
At 240 V the breaker clears 187 kA; at 415 V and 440 V it clears 121 kA; at 500 V it clears 75.6 kA; at 690 V it clears 3 kA — the steep drop at 690 V means this is really a 480 V / 600 V class MCCB, not a 690 V main.
