The Siemens SENTRON 3VA2063-5HL36-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current, designed for line protection in distribution panels and industrial switchgear. Its ETU320 electronic trip unit provides adjustable overload and short-circuit protection, with a maximum breaking capacity of 187 kA at 240 V and 121 kA at 415 V — meaning it safely clears high-fault currents without upstream coordination issues in most low-voltage networks.
SCCR & Selectivity
Breaking capacity drops predictably with voltage: 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 63 A rating holds flat across the full 40 °C to 70 °C ambient range — no derating needed for warm enclosures. Insulation voltage is rated 800 V, giving headroom for 480 V or 600 V class systems.
Integration & Mounting
Mounts on a standard DIN rail or direct panel-mount via the 105 mm width footprint. Depth is 86 mm, height 181 mm — fits a typical 200 mm deep enclosure without crowding the gland plate. No undervoltage release, no ground-fault monitoring, no communication function; this is a straight line-protection breaker with the ETU320 electronic trip.
Lifecycle & Sourcing
Listed as current production — no end-of-life notice. Sourced to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time. For a BOM freeze or line-down spare, the 3VA1110-5EE36-0AA0 is a functional peer in the same SENTRON family, but verify the lower SCCR and frame size before substituting.
