Product details

It mounts directly onto the matching S00 contactor — no DIN rail bracket needed, just snap it on the contactor's front face. The adjustable current response range is 0.45 to 0.63 A, set by a dial on the front. Trip class is Class 10, meaning it will trip within 10 seconds at 7.2× the current setting, which is the standard for standard-duty motor starting — adequate for most pump, fan, and conveyor applications that don't need a slower Class 20 or faster Class 5.

Rated operational current is 0.63 A at the top of the adjustment range, with a rated operational voltage of 690 V. The operating frequency is 50 to 60 Hz, so it covers both standard mains frequencies without derating. Power dissipation is 4.1 W typical at rated current, rising to 4.8 W in hot operating state. That's low enough that you don't need to worry about heat buildup inside a standard IP20 enclosure, but if you're packing multiple relays in a small panel, the cumulative heat matters. The per-pole dissipation is 1.6 W. Wire sizes accepted: 2× (0.5 to 1.5 mm²) solid or stranded, or 2× (0.75 to 2.5 mm²) finely stranded with ferrules. For AWG, that's 2× (20 to 16) solid or 2× (20 to 18) stranded. Tightening torque is 0.8 to 1.2 N·m — a standard screwdriver setting, no special tooling needed.

Mounts directly onto the S00 contactor (fastening method is contactor mounting). No DIN rail required if it's on the contactor; the contactor itself clips onto the DIN rail. Required spacing to grounded parts at the side is 6 mm — plan for that gap if you're laying out multiple contactor-relay pairs side by side. Dimensions: 76 mm height, 45 mm width, 70 mm depth. The depth is the overhang from the contactor face. It fits within the S00 envelope, so if you're replacing a failed relay on an existing S00 contactor, the footprint is identical. Environmental range: operating temperature -40 to +70 °C, transport/storage -55 to +80 °C. Relative humidity 0 to 90% during operation. Shock resistance 8g at 11 ms per IEC 60068-2-27.

Frequently asked questions

What is the adjustable current range?

The adjustable current response value is 0.45 to 0.63 A, set via a dial on the front of the relay.

What contactor size does this relay mount to?

It mounts directly onto the S00 contactor size (Siemens SIRIUS S00 frame). Fastening method is contactor mounting — no separate bracket needed.

What wire sizes and terminal type does it accept?

Screw-type terminals on both main and auxiliary circuits. Accepts 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²) finely stranded with ferrules. AWG equivalents: 2x (20 to 16) solid, 2x (20 to 18) stranded.

What are the physical dimensions?

Height 76 mm, width 45 mm, depth 70 mm.

What compliance documentation is available?

The part carries a substance prohibitance date of 05/01/2012, indicating RoHS compliance from that date. The insulation voltage rating of 690 V at pollution degree 3 and surge voltage resistance of 6 kV are verified per IEC standards.
