Siemens 3VA5160-6EF31-0AA0 U 60A 480V 3P Circuit Breaker

Siemens 3VA5160-6EF31-0AA0 is a three‑pole molded‑case circuit breaker in the UL 3VA5 frame (125 A frame), designed for industrial power distribution and motor control. It is rated In 60 A with a 65 kA short‑circuit breaking capacity at 480 V, making it suitable for 3‑phase feeders in demanding electrical installs. The device uses a TM240 thermal‑magnetic trip unit with ATAM, providing overload protection with Ir up to 60 A and instantaneous short‑circuit protection in the 5× to 10× In range (Ii), without external connections. Electrical ratings include a rated insulation voltage Ui of 800 V and a maximum operating voltage Ue of 690 V AC (DC 500 V). The breaker is UL listed under UL 489 for 3VA5 frame equipment, and is commonly used in distribution panels, MCCs, and feeders where reliable protection at 480 V is required.
