The Siemens SENTRON 3VA2163-5HN32-0JL0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V, so the SCCR you need drives the voltage you spec it at. The auxiliary switch configuration includes 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ), plus a shunt trip (STL) release built in — that covers remote tripping and status feedback without adding external modules.
What the interrupting ratings mean for your panel
The 187 kA at 240 V is the headline number, but the real-world decision is at your system voltage. At 415 V you get 121 kA — that's enough for most industrial distribution boards with a transformer upstream. At 690 V the rating drops to 3.7 kA, so this breaker is not your choice for 690 V high-fault installations; you'd step up to a higher-rated frame. The 63 A continuous rating holds flat from 40 °C to 70 °C, which means no derating curve to calculate if your panel runs warm — a solid fit for a crowded enclosure.
Mounting and integration
The breaker measures 105 mm wide, 181 mm high, and 86 mm deep — a standard MCCB footprint that fits most DIN-rail or panel-mount enclosures without surprises. The 3-pole design with line-protection designation means it's intended for feeder or branch-circuit duty, not motor protection (no thermal-magnetic curve for motor starting). The shunt trip (STL) allows remote opening via a control signal; the auxiliary switches provide status to a PLC or indication lamp.
