The main current circuit uses spring-loaded terminals accepting 2x (0.25... 2.5 mm²) solid or stranded wire, which speeds panel wiring compared to screw terminals and holds up better under vibration. The integrated surge suppressor uses full-wave rectification, meaning the coil drive includes a built-in suppression circuit that handles the inductive kick without requiring an external varistor or RC snubber. This simplifies wiring and reduces panel clutter. The AC-3 rating of 4 kW at 690 V defines the motor-switching capability for squirrel-cage motors — starting and disconnecting under load. At 500 V the same duty yields 3.5 kW. For resistive or lightly inductive loads (AC-1), the contactor handles up to 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V. These are the currents the main contacts can make and break without excessive wear. The AC-4 rating of 6.5 A at 400 V covers inching and plugging duty — frequent starts and reversals that generate more arc energy than AC-3. If your application involves jogging or reversing under load, this is the rating to size against. The auxiliary contact block (1 N/O instantaneous) is integrated, and the terminal design allows for solid or stranded wire up to 2.5 mm² (AWG 14). The clearance to adjacent components on the side is 6 mm.","metaTitle":"Siemens SIRIUS 3RT1015-2GG28-0NA4-ZX95 Power Contactor, S00,","metaDescription":"Siemens SIRIUS 3RT1015-2GG28-0NA4-ZX95 power contactor, size S00, 4 kW at 690 V AC-3.

If your panel is wired for screw terminals and you need a drop-in replacement without retooling the wiring, the 3RT1016-2AP02 is the form-fit-function alternative. The 3RT1015-1BB42 is another S00 variant but with different coil voltage and terminal style — verify coil compatibility before substituting."},{"question":"What is the depth of this contactor?","answer":"The depth is 114 mm, measured from the mounting surface to the furthest projection of the contactor body. This fits standard 200 mm deep enclosures with room for wiring clearance."},{"question":"What wire sizes does the spring-loaded terminal accept?","answer":"The main circuit terminals accept 2x (0.25... 2.5 mm²) solid or stranded wire, or 2x (24... 14 AWG). The spring-cage design requires no screw tightening — strip to 8-10 mm and push in."},{"question":"Will this contactor fit a panel designed for 3RT1016-2AP02?","answer":"Yes, both are size S00 with the same 45 mm width and DIN rail mounting pattern.
