Part identity and key ratings
The Siemens SENTRON 3VA2063-5JP36-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current, with an ETU550 electronic trip unit designed for line protection. It carries a maximum breaking capacity of 187 kA at 240 V, derating to 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 operating temperature range from 40 °C to 70 °C — no derating needed for elevated panel ambient temperatures. The ETU550 trip unit provides adjustable overload and short-circuit protection with communication capability, making this breaker suitable for integration into monitored power distribution systems. The front face carries IP40 protection — fine for enclosed panel mounting.
Dimensions and panel fit
The breaker measures 105 mm wide, 181 mm high, and 86 mm deep. The 105 mm width is standard for a 3-pole frame in the 3VA2 series, so it fits existing SENTRON panel cutouts and busbar arrangements without modification.
Lifecycle and sourcing
This order code carries a current production lifecycle stage — it is still in active manufacture. No end-of-life notice or successor replacement has been issued. Sourcing is straightforward through the standard Siemens distribution channel; availability and current pricing are confirmed at quote time against an RFQ.
