Product details

Its adjustable current response covers 11 to 16 A, and the Trip Class 10 rating means it will trip within 10 seconds at 7.2× the set current — fast enough to protect standard induction motors during a locked-rotor event without nuisance tripping on normal starts. The relay accepts screw-type terminals for both the main and auxiliary circuits.

The 11–16 A adjustable range sets the thermal pickup point: you dial it to the motor's nameplate full-load current. The S00 contactor size means this relay clips directly onto the matching S00 frame contactor, saving panel space.

Frequently asked questions

How do you wire 3RU6116-4AB1 overload relay?

The main current circuit uses screw-type terminals accepting 2x (0.5–1.5 mm²) solid or stranded, or 2x (0.75–2.5 mm²). The auxiliary/control circuit also uses screw terminals. Tightening torque for main contacts is 0.8–1.2 N·m.
