The Siemens SENTRON 3VA2063-6HN42-0AA0 is a 4-pole molded case circuit breaker rated for 63 A continuous current at 40 °C through 70 °C, meaning no derating is needed across the full panel ambient range. The ETU350 electronic trip unit provides line protection with adjustable overload and short-circuit settings. Interrupting capacity reaches 242 kA at 240 V, 187 kA at 415/440 V, and 121 kA at 500 V — enough to clear high-fault conditions without cascading upstream breakers. Insulation voltage is rated at 800 V, with a maximum operating temperature of 70 °C and storage from -40 °C to 80 °C.
Dimensions are 86 mm deep, 140 mm wide, 181 mm high. The 4-pole form factor fits standard panel layouts; front IP40 protection keeps debris out of the breaker face in enclosed panels. No undervoltage release, no communication function, no ground-fault monitoring — this is a straight line-protection breaker with the ETU350 trip unit. Power loss is 5.4 W maximum at rated current.
No trip indicator is fitted, so fault events won't be visually flagged on the breaker itself — plan for remote indication via auxiliary contacts if needed. The 63 A rating holds steady across the full 40–70 °C range, which simplifies coordination in dense panels where ambient can climb.
