Product details

It mounts directly to a matching S00 contactor, forming a compact motor starter assembly for DIN-rail or panel-mount enclosures. Rated operational current is 6.3 A at up to 690 V AC/DC, 50/60 Hz, with a CLASS 10 trip characteristic — meaning it will trip within 10 seconds at 7.2× the current setting, appropriate for standard induction motor starting profiles where the rotor doesn't stall.

The 6.3 A rated operational current sets the maximum continuous motor FLA this relay can protect. For a motor drawing, say, 5.5 A FLA, this relay adjusts down to cover it — the setting range is typically 0.1× to 1.0× of the rated value, so it covers motors from roughly 0.63 A up to 6.3 A. Mounting position allows ±135° rotation and ±45° tilt from vertical, giving flexibility in tight panel layouts. Side spacing to grounded parts must be at least 6 mm to maintain rated insulation.

Frequently asked questions

What is the trip class and why does it matter?

It is CLASS 10, which means the relay will trip within 10 seconds at 7.2× the current setting. This suits standard induction motors that accelerate quickly and do not experience prolonged locked-rotor conditions.

What contactor size does this relay mount to?

It mounts to any S00-size Siemens contactor (e.g., 3RT2 series) via the contactor mounting method, forming a compact motor starter assembly.

What are the terminal wire ranges?

Screw terminals accept 2× (0.5 to 1.5 mm²) solid or stranded, or 2× (0.75 to 2.5 mm²) finely stranded with ferrule. Tightening torque is 0.8 to 1.2 N·m.
