Product details

Mounting and wiring — contactor-fit checklist

The 3RB3016-1SB0: Fastening method is direct contactor mounting — the relay snaps onto the SIRIUS S00 contactor without extra DIN-rail space, saving width in the panel. A Pozidriv PZ2 tip and 5–6 mm shaft diameter are needed for the M3 main contacts.

The note "for message 'tripped'" indicates the auxiliary contact position changes only when the relay has actually tripped on overload — it does not follow the reset state or power loss, so the PLC sees a clean trip signal.

Environmental and mechanical ruggedness

Shock resistance is 15 g / 11 ms for the relay body; the signaling contact in the tripped position withstands 9 g / 11 ms per IEC 60068-2-27. Vibration resistance covers 1–6 Hz at 15 mm amplitude and 6–500 Hz at 20 m/s² for 10 cycles. Power dissipation per pole is 0.2 W — negligible heat load in the panel.

Sourcing and lifecycle — current production, quoted to order

Substance prohibitance date is 10/01/2009 — the relay complies with RoHS and REACH substance restrictions as of that date.

Frequently asked questions

Where can I buy 3RB3016-1SB0 and how do I get a price?

Sourced to order against the BOM quantity through independent distribution.

What is 3RB3016-1SB0's listed note (for message "tripped")?

The note "for message 'tripped'" means the auxiliary contact signals only when the relay has tripped on overload — it does not indicate reset state or power loss, giving a clean trip signal to the PLC.

What is 3RB3016-1SB0's listed depth?

Depth is 73 mm, width 45 mm, height 79 mm — size S00 frame for direct contactor mounting.

What compliance documentation does Siemens provide for 3RB3016-1SB0?

Substance prohibitance date is 10/01/2009 — the relay complies with RoHS and REACH substance restrictions. Siemens provides RoHS, REACH, UL, and IEC documentation on request.
