Product details

The Siemens SIRIUS 3RB3016-1SB0-ZX95 is a solid-state overload relay in size S00, designed for motor protection in control panels where electronic overload release and a Class 10E trip curve are specified. Rated thermal current is 12 A at up to 690 V, so it covers the full motor FLA range for small drives up to that current. The integrated auxiliary switch provides a dedicated "tripped" signal for the PLC or annunciator — no separate aux block needed.

Trip curve and signal

Class 10E trip curve. Electronic overload release compensates from -25 to +60 °C. Integrated auxiliary contact delivers a positive "tripped" message.

Fastens directly to the contactor — no DIN-rail bracket needed, so it adds no extra width to the motor starter assembly. Size S00 footprint (45 mm wide, 79 mm tall, 73 mm deep) keeps the starter stack compact. Screw terminals on the main circuit accept 1x (0.5…4 mm²) or 2x (0.5…2.5 mm²) solid/stranded, Pozidriv PZ2 driver.

Frequently asked questions

What is the 3RB3016-1SB0-ZX95's listed note for message "tripped"?

The part is specified "for message 'tripped'", meaning its integrated auxiliary contact is dedicated to signaling the tripped state — useful for a hardwired fault indication.
