It's a line-protection design, meaning it's built for feeder circuits, not motor protection with adjustable overloads. That's unusual for an MCCB; most start tapering above 40 °C. Dimensions are 181 mm high, 105 mm wide, 86 mm deep — a 3-pole frame that fits standard 105 mm-wide panel cutouts. The depth is shallow enough that it won't interfere with gland plates or rear-panel wiring in most enclosures. That's a lot of status feedback for a line-protection breaker — useful if your PLC or BMS needs to know the breaker state without separate contactors. ## Sourcing and lifecycle — active production, quoted to order The basic switch assembly inside is order code 3VA20636HL320AA0, so if you're rebuilding a failed unit rather than replacing the whole breaker, that subcomponent is traceable. The UVR is built in, not a field-add kit — verify your control voltage matches before wiring. The 63 A rating is continuous across that entire operating band, as noted — so if your panel sits in an unventilated steel shed in summer, this breaker won't surprise you with a derate. ## Comparison with 3VA2163-5HL32-0DB0 The closest functional peer is the 3VA2163-5HL32-0DB0. Both are 63 A, 3-pole SENTRON MCCBs with similar interrupting ratings. The key difference: the -0BL0 carries an undervoltage release and a full set of auxiliary/trip/alarm switches (2+1+1), while the -0DB0 typically ships with fewer auxiliaries and no UVR. If your panel requires the UVR for safe-start interlocking or emergency-stop chain, the -0BL0 is the correct BOM line. If you don't need the UVR and can add aux contacts separately, the -0DB0 may be a simpler fit. Footprint and mounting are identical — they swap without rewiring.","metaTitle":"Siemens 3VA2063-6HL32-0BL0 SENTRON MCCB, 63A, 242kA at 240V","metaDescription":"Siemens 3VA2063-6HL32-0BL0 SENTRON molded case circuit breaker, 63 A continuous, 242 kA interrupting at 240 V.
