Product details

Solid-state overload relay, Size S00, CLASS 10E

The Siemens 3RB3016-1RB0 is a SIRIUS solid-state overload relay in Size S00, rated for a thermal current of 0.4 A at up to 690 V rated value. Mounting is via direct contactor mounting onto a SIRIUS contactor frame — no separate DIN-rail clip required. Screw-type terminals on the main current circuit accept 1× (0.5 to 4 mm²) or 2× (0.5 to 2.5 mm²) solid or stranded conductors; the screwdriver tip is Pozidriv PZ2 with a 5 to 6 mm shaft diameter.

Signaling contact ratings

The integrated auxiliary switch (signaling contact 97/98) carries the following rated currents: 2 A at 24 V, 4 A at 120 V, 3 A at 230 V, 0.55 A at 60 V, 0.3 A at 110 V, 0.3 A at 125 V, and 0.11 A at 220 V. The contact's shock resistance is 15g / 11 ms in the normal state, derated to 9g / 11 ms in the tripped position per IEC 60068-2-27.

Frequently asked questions

What is the 3RB3016-1RB0's trip class and what does it mean?

The trip class is CLASS 10E, meaning the relay will trip within 10 seconds at 7.2× the current setting under cold-start conditions. This is the standard protection class for standard induction motors, allowing them to accelerate under load without nuisance tripping.

What is the note 'for message tripped' on this component?

The note 'for message tripped' refers to the signaling contact's function — it provides a dry-contact indication when the overload relay has tripped, typically wired to a PLC digital input or an alarm annunciator.

Does the 3RB3016-1RB0 mount directly to a contactor?

Yes, the fastening method is contactor mounting — it snaps directly onto a compatible SIRIUS contactor frame without requiring a separate DIN-rail adapter. The Size S00 footprint matches the corresponding S00 contactor.

What compliance documentation does Siemens provide for the 3RB3016-1RB0?

The relay carries a substance prohibitance date of October 1, 2009, confirming RoHS compliance. The design also references IEC 60068-2-27 for shock resistance. Full declarations (CE, UKCA, EAC) are typically included with the manufacturer's documentation package.

How do I get current pricing and availability for the 3RB3016-1RB0?

This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and delivery estimate.
