Siemens 3RB1016-2NB0 Relay

Siemens 3RB1016-2NB0 is a compact solid‑state overload relay that mounts on size S00 contactors to protect small motors, delivering reliable protection for a current range of 0.4–1.6 A with Class 20 thermal characteristics. It uses screw terminals for straightforward wiring and offers a manual‑automatic reset option, allowing either manual reset after an overload or automatic reset according to the control scheme. The relay includes one normally open and one normally closed auxiliary contact, enabling signaling or interlock functions without extra modules. Designed for use in Siemens motor-protection schemes, it pairs with Siemens 3RT1015, 3RT1016, or 3RT1017 contactors to form a compact, integrated protection solution for small drives and conveyors.
