The note on this variant says \"Tripped,\" which is the message the relay sends back to the PLC or indicator light when it's done its job. Mounting is straight contactor-mount — no DIN rail needed, it snaps onto the bottom of the matching contactor (3RT5036 frame). The screw-type terminals on the main circuit accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded wire. The auxiliary switch is integrated, so you get one N/C and one N/O contact built in. The Pozidriv PZ 2 screwdriver tip is what you want on the van for the terminal screws. The auxiliary contact ratings cover a wide control-voltage range: 2 A at 24 V, 0.3 A at 60 V, 0.22 A at 110 V, 3 A at 120 V, 0.22 A at 125 V, 0.11 A at 220 V, 2 A at 230 V, and 1 A at 400 V. That's enough to switch most PLC inputs, relay coils, and indicator lamps directly — no intermediate relay needed for most 24 VDC or 120 VAC circuits.","metaTitle":"Siemens 3RU2136-4EB0-ZX95 SIRIUS Thermal Overload Relay, Cla","metaDescription":"Siemens SIRIUS 3RU2136-4EB0-ZX95 thermal overload relay, Size S2, Class 10, contactor-mount.
