Siemens 3VA2063-5KP32-0DL0 — SENTRON MCCB, 63 A, 3-Pole, Line Protection
The Siemens 3VA2063-5KP32-0DL0 is a SENTRON molded case circuit breaker (MCCB) designed for line protection, carrying a continuous rated current of 63 A across its full ambient temperature range from 40 °C to 70 °C — no derating needed up to that ceiling. Rated for 3-pole operation, it delivers interrupting capacities of 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V — the 187 kA figure at 240 V gives substantial headroom for high-fault industrial service entrances where available short-circuit current is high. The adjustable thermal-magnetic trip unit is set for a minimum of 95 A and maximum of 756 A, allowing the breaker to be tuned to the actual load without swapping trip packs.
Fit and Configuration — Auxiliaries, Communication, and Mounting
This MCCB comes factory-fitted with an undervoltage release (UVR) and a full auxiliary switch block: 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ type). A communication function is built in, enabling integration with higher-level control or monitoring systems — useful for remote trip indication or load-shedding schemes. The trip indicator is present, so a visual check confirms whether the breaker tripped on fault versus being manually opened. Physical footprint: 105 mm wide, 181 mm high, 86 mm deep — standard for this SENTRON frame size, fitting common panel layouts and DIN-rail or screw-mount installations. Power loss is rated at 7.9 W maximum — manageable for thermal budgeting inside a sealed enclosure, but worth checking against the panel's dissipation limits if multiple breakers are ganged.
