Siemens 3VA4130-6ED34-0AA0 Molded Case Circuit Breaker

Siemens 3VA4130-6ED34-0AA0 Molded-Case Circuit Breaker is a 3-pole protection device in the UL Frame 125 family, rated for 600 V AC and a nominal current of 30 A. Designed for panel protection in 50/60 Hz systems, this 3VA4 device provides thermal-magnetic overcurrent protection with a fixed overload setting Ir of 30 A and a short-circuit setting Ii of 10 × In, enabling reliable interruption for faults up to 65 kA at 480 V (class H). It carries UL 489 markings and supports HACR-type applications. The unit features lug connections for aluminum conductors (8 to 3/0 AWG) with load-end terminals for straightforward installation, and it is housed in an IP40 enclosure. Weighing about 0.743 kg, its dimensions are approximately 5.5 in high, 3 in wide, and 3.7 in deep, and it is rated for operation on 50/60 Hz systems from -25 °C to 70 °C. Mechanical endurance is listed at 15,000 cycles, with electrical endurance of 8,000 cycles at 480 V and 4,000 cycles at 600 V. This model supports neutral conductor retrofitting and, as a variant, does not include a ground-fault monitoring version.
