Product details

It mounts directly onto a matching S00 contactor, forming a compact motor starter assembly for a control panel. Rated operational current is 0.4 A, with a Trip Class 10 characteristic — meaning it will trip within 10 seconds at 7.2× the set current, fast enough to protect standard induction motors during a stalled rotor or locked-rotor condition. The relay handles main circuit voltages up to 690 V at 50/60 Hz.

Fastens directly to a S00 contactor via the contactor mounting method — no separate DIN-rail clip needed for the relay itself, though the contactor typically snaps onto a DIN rail. The relay's screw-type terminals for both main and auxiliary circuits accept 2× (0.5…1.5 mm²) or 2× (0.75…2.5 mm²) solid or stranded wire, with a tightening torque of 0.8…1.2 N·m. Dimensions are 78 mm deep, 45 mm wide, 87 mm tall. IP20 on the front and at the terminals — suitable for enclosed panels where no washdown or dust ingress is expected. Mounting position allows rotation ±135° or tilt ±45° from vertical, giving flexibility in tight enclosures.

Frequently asked questions

What are the key ratings for the 3RU7116-0EB0?

Rated operational current is 0.4 A, Trip Class 10, with a rated insulation voltage of 690 V AC at 50/60 Hz. Auxiliary contacts are rated 3 A at 24 V and 2 A at 230 V. Power loss is 4.8 W total at rated current in hot operating state.

What contactor does the 3RU7116-0EB0 mount to?

It mounts directly to a Siemens SIRIUS S00 contactor via the contactor mounting method. The size S00 designation ensures mechanical and electrical compatibility with the matching contactor frame.

What is the physical size of this overload relay?

Depth is 78 mm, width is 45 mm, height is 87 mm. It fits the S00 contactor footprint and requires 6 mm spacing to grounded parts at the side.
