The 10 A maximum at 24 V covers the typical current draw of a PLC input module or a small contactor coil. The AC-15 rating of 1 A at 690 V is the key figure for switching solenoid loads in a 400–690 V panel — AC-15 is the utilization category for electromagnetic loads (contactors, relays), so this switch is rated for the inrush and inductive kick those loads produce. The snap-on mounting lets it clip directly onto the front of the contactor or relay without tools, saving DIN-rail space and keeping the wiring within the same vertical column. ## Integration note The dimensions — 36 mm wide, 37.5 mm high, 43.7 mm deep — are compact enough to fit on the front of the contactor without protruding past the mounting base. The screw terminals accept 2x (0.5…1.5 mm²) or 2x (0.75…2.5 mm²) conductors, or the AWG equivalents 2x (20…16) and 2x (18…14).","metaTitle":"Siemens 3RH2911-1HA02-ZW96 Auxiliary Switch, 2 NC, 10 A, IP2","metaDescription":"Siemens SIRIUS 3RH2911-1HA02-ZW96 auxiliary switch, 2 NC contacts, rated 10 A at 24 V, AC-15 1 A at 690 V.
