The Siemens 3VA4135-4ED24-3AA0 is a 2-pole circuit breaker from the 3VA4 UL Frame 125 series, rated for 35 A continuous current with a breaking capacity of 25 kA at 480 V (class S). The TM210 trip unit provides fixed thermal-magnetic protection: overload protection (Ir) is permanently set at 35 A, and short-circuit protection (Ii) is fixed at 10 × In (350 A). This is a line-protection breaker, not a motor-protection device — it responds to the thermal curve of a cable, not a motor's startup inrush.
Compliance and regulatory posture
RoHS compliant since 13-05-19. The 3VA4 series carries UL and IEC certifications by design, though the specific listing numbers are not in this record; the UL Frame 125 designation confirms UL 489 listing for the frame.
