Side-by-side mounting is allowed with zero gap — the 6 mm side clearance spec is for air circulation, not mandatory spacing. At 45 mm wide, it fits standard 45 mm slot in a modular enclosure row. AC-3 motor switching: 4.5 kW at 500 V, 5.5 kW at 690 V. That's the rating that governs real motor loads — pumps, fans, compressors. The auxiliary contact ratings cover control circuits: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 0.3 A at 220 V DC — enough for most PLC output or relay interface signals. Mechanical endurance is 30 million operating cycles typical — a high figure for an S00 frame, suited for frequent cycling applications like conveyor diverters or packaging machinery. For type 2 coordination (contactor remains usable after a fault), use a 20 A gL/gG fuse. The varistor across the coil suppresses switching transients — no external RC snubber needed for the DC coil. The spring-loaded terminals accept 2x 0.25 to 2.5 mm² solid or stranded, or 2x 24 to 14 AWG — standard for panel wiring. Strip length and ferrule use follow the manufacturer's termination guide; the spring clamp holds firm under vibration common in machine-mounted enclosures.","metaTitle":"Siemens 3RT1016-2KB42-ZX95 SIRIUS Power Contactor, 24V DC Co","metaDescription":"Siemens SIRIUS 3RT1016-2KB42-ZX95 power contactor, size S00, 24V DC coil, spring-loaded terminals, IP20.
