Siemens 3VA4150-5ED34-0AA0 Molded Case Circuit Breaker

Siemens 3VA4150-5ED34-0AA0 is a three-pole molded-case circuit breaker (MCCB) from the 3VA4 family, engineered to protect three‑phase power circuits in industrial and commercial distribution systems. It is rated for 50 A nominal current and supports voltages up to 600 V AC, combining thermal and magnetic trip action to provide overload and short‑circuit protection in a compact enclosure. This model adheres to international standards, including IEC 60947-2 and UL 489, making it suitable for global applications such as motor control centers, switchboards, and distribution panels where reliable three‑phase protection is required. The exact 3VA4150-5ED34-0AA0 designation identifies the 50 A rating within the 3VA4 series, and the 3P configuration ensures coordinated protection across all three live conductors in a single device.
