Siemens 3VA4160-4ED34 Molded Case Circuit Breaker

Siemens 3VA4160-4ED34-0AA0 is a three‑pole molded‑case circuit breaker (MCCB) in the 3VA4 UL frame designed for distribution and motor protection in 480 V ac circuits. It provides a 60 A nominal current rating with a thermal‑magnetic trip unit (TM210) for overload and short‑circuit protection and carries a 25 kA interrupting capacity at 480 V (class S). This unit is UL 489 listed and HACR‑type, suitable for heating, air conditioning, and refrigeration applications, with a net weight of 0.743 kg. Electrical endurance is specified as 8,000 cycles at 480 V and 4,000 cycles at 600 V, while mechanical life is rated around 15,000 cycles. The device derates with ambient temperature: 60 A at 40 °C down to 53 A at 70 °C, reflecting typical installation environments. Terminal connections are listed as none for clamp (clamp connection: None). The model designation—60 A, 3‑pole, 480 V—supports branch protection in panels or motor circuits, and its compact 3VA4 form factor aligns with standard OEM and panel‑builder requirements for reliable, code‑compliant overcurrent protection.
