Product details

Rated operational current is 0.8 A, so it's sized for fractional-horsepower motors or small transformer loads on a 690 V AC/DC main circuit.

This relay snaps onto S00-frame contactors (same frame size) without extra hardware — no DIN rail required, though the assembly itself can be DIN-rail mounted. The mounting position allows ±135° rotation and ±45° tilt forward/backward from vertical, giving panel builders flexibility in tight enclosures. Side spacing of 6 mm to grounded parts is required. Screw-type terminals on both main and auxiliary circuits accept 2× (0.5…1.5 mm²) solid or 2× (0.75…2.5 mm²) stranded; torque to 0.8…1.2 N·m.

Frequently asked questions

Where can I buy 3RU7116-0HB0 and get a price?

The 3RU7116-0HB0 is sourced to order against an RFQ through independent distribution. Submit a request with your quantity; availability and current pricing will be confirmed at quote time.

What is the depth of 3RU7116-0HB0?

The listed depth is 78 mm, width 45 mm, height 87 mm — compact enough for dense S00-frame contactor assemblies.

What compliance documentation does Siemens provide for 3RU7116-0HB0?

The relay carries IP20 finger-safe protection on the front and terminals. It is rated for 6 kV surge voltage resistance and 690 V insulation at pollution degree 3. Standard Siemens documentation includes the declaration of conformity for CE/UKCA; UL and CSA listings are typical for the SIRIUS family but should be verified against the specific product label for this date code.
