What this MCCB carries and where it fits
The Siemens SENTRON 3VA2110-5JP32-0CC0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to that ceiling. Breaking capacity sits at 187 kA at 240 V AC, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3.7 kA at 690 V. That spread covers most industrial distribution panels and motor control centers where high fault current is a given. This is a line-protection design (not feeder or motor-protection profile), so it's suited for main or branch circuits where the priority is short-circuit and overload isolation rather than motor thermal overload curves. It includes an undervoltage release (UVR) and carries a communication function — meaning it can report status or trip events to a higher-level control system, which saves a wiring run back to the PLC for a separate aux contact.
Physical fit and panel integration
Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep. The 86 mm depth matters when the panel door clearance is tight; check that the handle and any rotary-drive extension clear the enclosure cover. Power loss is rated at 12.5 W maximum at rated current — negligible for thermal budgeting inside a sealed enclosure, but worth noting if the panel packs multiple breakers in a row with limited airflow.
