The Siemens 3RT2516-1AD00-ZX95 is a SIRIUS contactor in the compact S00 frame, with a 24 V AC 50/60 Hz coil and screw-type terminals. The S00 frame typically handles motor loads up to 7.5 kW at 400 V AC-3, though the exact rating depends on the specific coil variant and auxiliary block configuration.
That 6 mm side gap is the only spacing constraint — useful when packing multiple contactors into a tight row.
Screw-type terminals on the coil accept solid or stranded conductors: 2× (0.5…1.5 mm²), 2× (0.75…2.5 mm²), or 2× 4 mm². The auxiliary switch is included, which simplifies ordering if you need a feedback contact for the PLC or a status signal for the HMI — no separate add-on block required for basic N/O or N/C signaling.
Switching performance and ratings
Rated operational current at AC-15 (solenoid/contactor control) is 10 A at 24 V and 10 A at 230 V, 50/60 Hz. At 400 V AC-15 it's 3 A; at 600 V it drops to 0.1 A — so this contactor is primarily a 24–230 V control-circuit device, not a 480 V+ power contactor. DC switching capability is present but limited: 10 A at 24 V DC, 2 A at 48/60/125 V DC, 0.8 A at 440 V DC. Maximum mechanical switching frequency is 30,000,000 operations; at AC-1 resistive load it can cycle up to 1,000 operations per hour, and at DC load up to 10,000 operations per hour.
It's still a standard catalog line, not a last-time-buy or NRND situation. That said, the -ZX95 suffix often indicates a special version or customer-specific variant, so if you're replacing an existing panel part, verify the exact coil voltage and auxiliary configuration against the nameplate.
