Siemens 3VL4860-3KN30-0AA0 VL400X UL 3-Pole High Breaking Capacity Circuit Breaker
The Siemens 3VL4860-3KN30-0AA0 is a VL400X molded case circuit breaker designed to meet UL 489 standards, identified as UL type LG with catalog number LLX3B600. This 3-pole breaker has a non-interchangeable frame and offers a very high breaking capacity of 100kA at 480V AC and 18kA at 600V AC. It features a TM trip unit with LI functionality, rated for a maximum of 600A (In < 600A). The short-circuit protection (II) is set at 2750A to 5500A, with the overload protection (IR) fixed at 600A. This unit is intended as a spare part for replacement, supplied without connection accessories, auxiliary releases, or alarm switches.
This circuit breaker is suitable for heavy-duty industrial applications in North America that demand UL 489 compliance and a very high interrupting rating, such as in main distribution panels, large motor circuits, and systems with significant fault current potential. The TM trip unit provides robust protection.
