Siemens AG 3VU16001MN100 Motor Overload Relay

Siemens 3VU1600-1MN00 is a motor protection circuit breaker designed to protect small- to mid-size motors in low-voltage circuits, integrating an overload release adjustable from 16 to 25 A with a high short-circuit breaking capacity. This compact unit belongs to the Siemens 3VU family and features screw-type terminals, a 52/63 A frame size, and an integrated auxiliary contact arrangement of 1NO+1NC for signaling in motor starters. The overload release is rated 16–25 A (A), and the instantaneous overcurrent release (N) is listed around 300 A, with a rated breaking capacity of 100 kA at 400 V. Designed for use with Siemens contactors and motor control panels, it provides protection for motors in the 16–25 A range and is commonly deployed in size 52/63 A installations.
