Product details

0.22-0.32 A adjustable overload, Class 10 trip curve

The 3RU6116-0DB0: It mounts directly onto S00-frame contactors via the contactor mounting fastening method, forming a matched motor starter package that shares the same 45 mm width and 76 mm height footprint. The thermal bimetallic release is ambient-compensated across the -40 to +70 °C operating range and handles 50/60 Hz main circuits up to 690 V with a rated impulse withstand of 6 kV.

Screw terminals, wire ranges, and panel fit

Both main and auxiliary circuits use screw-type terminals accepting 2× (0.5-1.5 mm²) solid/stranded or 2× (0.75-2.5 mm²) finely stranded with ferrule, plus AWG equivalents down to 2× 12 for the mains and 2× 14 for auxiliaries. Depth is 70 mm, width 45 mm, height 76 mm — the S00 envelope fits standard motor starter rows without crowding adjacent devices.

Active production, compliance, and sourcing

Total typical power loss is 4.5 W, with per-pole dissipation of 1.6 W at rated current — the 4.8 W hot-state figure is the ceiling for enclosure thermal budgeting.

Frequently asked questions

What contactor size does this relay mount to?

It mounts directly onto S00-frame contactors using the contactor mounting fastening method, forming a compact motor starter package.
