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.
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. 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.
