S00 frame solid-state overload relay, contactor-mounted
The Siemens 3RB3016-1PB0-ZW96 is a SIRIUS solid-state overload relay in the S00 frame size, designed for direct mounting onto a contactor — no separate DIN-rail footprint needed. Rated thermal current is 4 A continuous, with a maximum operating voltage of 690 V (AC-3e rated value). The trip class is CLASS 10E, meaning it will trip within 10 seconds at 7.2× the set current — fast enough to protect standard squirrel-cage motors during a locked-rotor event.
Auxiliary contact ratings and wiring
The integrated auxiliary switch (signaling contact 97/98) is rated for switching at multiple control voltages: 2 A at 24 V, 4 A at 120 V, 3 A at 230 V, and 0.55 A at 60 V — covering most PLC input and relay coil circuits in a panel. Terminals accept 1x (0.5 to 4 mm²) or 2x (0.5 to 2.5 mm²) solid or stranded wire, with screw-type connections requiring a Pozidriv PZ2 tip. The relay measures 45 mm wide × 79 mm high × 73 mm deep — fits the S00 contactor footprint without crowding adjacent devices.
Environmental and mechanical endurance
Operating temperature range is -25 to +60 °C with temperature compensation active across that band — no derating needed for ambient heat up to 60 °C. Storage and transport range extends from -40 to +80 °C. Rated shock resistance is 15g / 11 ms per IEC 60068-2-27 (signaling contact in tripped position: 9g / 11 ms). Vibration resistance covers 1–6 Hz at 15 mm amplitude and 6–500 Hz at 20 m/s² for 10 cycles — suitable for machine-mounted applications with moderate vibration.
Lifecycle and sourcing
Substance prohibitance date is 10/01/2009, indicating RoHS compliance per the manufacturer's declaration.
