The Siemens SENTRON 3VA2063-5HL36-0BA0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current, designed for line protection in distribution panels. Its 187 kA interrupting capacity at 240 V (121 kA at 415 V, 75.6 kA at 500 V, 3 kA at 690 V) means it can safely clear high-fault currents without cascading upstream — critical for main or feeder breakers in industrial switchgear where available fault current is high. This MCCB carries an integrated undervoltage release (UVR), so it trips automatically when supply voltage drops below a set threshold — a common requirement for motor branch circuits where you need to prevent automatic restart after a brownout. The 800 V rated insulation voltage gives headroom for 480/600 V class systems. Dimensions are 181 mm high, 105 mm wide, 86 mm deep — fits standard MCCB panel cutouts. Rated continuous current holds flat at 63 A across the full -25 °C to 70 °C operating range, so no derating needed in a warm enclosure. Power loss is 7.9 W maximum.
Lifecycle & Sourcing
For BOM freeze or compliance documentation, the SENTRON series carries standard IEC/UL certifications (the 3VA platform is designed to IEC 60947-2 and UL 489). RoHS and REACH declarations are available from Siemens on request.
Integration Note
Panel integration: the 105 mm width and 86 mm depth fit standard MCCB mounting footprints. The undervoltage release coil draws from the control circuit — verify the supply voltage matches the release rating before wiring. No communication function on this variant; it's a standalone thermal-magnetic or electronic trip unit (line protection design).
