SIRIUS S00 Power Contactor — Panel Integration Notes
The Siemens 3RT2016-4AR61 is a SIRIUS S00 power contactor — the smallest frame size in the SIRIUS family, sized for motor loads and resistive switching in control panels up to 400 V AC 50 Hz or 440 V AC 60 Hz coil supply. Mounting is via screw fixing or snap-on onto 35 mm DIN rail per DIN EN 60715; the mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward, giving panel builders flexibility in crowded enclosures. The coil connection uses a ring cable lug termination, a detail that affects wiring preparation — ensure ring lugs are crimped before installation.
Mechanical endurance is rated at 30,000,000 operating cycles typical; electrical endurance varies by duty: 1,000,000 cycles at AC-1 maximum, 750,000 at AC-2 and AC-3 maximum, 250,000 at AC-4 maximum, and 750,000 at AC-3e maximum. Arcing time spans 10 to 15 ms; the contactor's switching time at AC is 4 to 15 ms — both figures matter for coordination with upstream protection devices. Auxiliary contact switching capacity is voltage-dependent: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, 0.2 A at 440 V, 7.6 A at 480 V, and 2 A at 500 V — derate accordingly for your control circuit.
An auxiliary switch is fitted as standard, simplifying integration without additional add-on modules.
