Siemens SENTRON 3VA2163-5HL46-0AA0 — 63 A MCCB for Line Protection
The Siemens SENTRON 3VA2163-5HL46-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for 63 A continuous current, designed for line protection in distribution panels and industrial switchgear. It carries an adjustable thermal-magnetic or electronic trip range from a minimum of 95 A up to a maximum of 756 A, meaning the trip threshold can be field-set to match the protected conductor or load without swapping the breaker frame. The ETU320 electronic trip unit provides selectable overload and short-circuit protection curves, suited for coordinating with downstream breakers in a selective distribution scheme. Breaking capacity is rated at 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — the 240 V figure covers the highest fault-current scenario typical in North American 277/480 V panelboards, while the 415/440 V ratings handle European 400 V industrial mains. Rated insulation voltage is 800 V, and the front face carries IP40 protection. Power loss is 4 W maximum at rated current, which is negligible for thermal budgeting inside a crowded panel.
Integration — Panel Fit and Mounting
Dimensions are 181 mm height, 140 mm width, and 86 mm depth — a standard 4-pole MCCB footprint that mounts directly onto a DIN rail or panel-mount adapter in a distribution board. Operating temperature range is -25 °C to 70 °C, with storage from -40 °C to 80 °C, covering most indoor industrial and commercial environments without derating.
