Siemens 3RT2017-1AP02 SIRIUS Power Contactor 12A 5.5kW 3P 230V AC

The Siemens 3RT2017-1AP02 is a SIRIUS 3RT2 power contactor rated at 12 A and 5.5 kW at 400 V in AC-3/AC-3e duty, for switching three-phase AC loads and motors. It is controlled by a 230 V AC coil at 50/60 Hz and includes one normally-closed auxiliary contact. Size S00 with screw terminals keeps the unit compact for use in space-limited control cabinets.

Features and benefits:

• Mechanical service life of 30 million operating cycles supports long-term high-cycle applications
• Low power loss of 1.5 W at rated current limits heat build-up inside enclosures
• Operating frequency up to 750 switching operations per hour in AC-3 duty
• Closing delay 9 to 35 ms and opening delay 4 to 15 ms give predictable control timing
• Coil pick-up power 37 VA at 50 Hz, holding power drops to 5.7 VA to reduce steady-state energy draw

Applications:

• Direct-on-line starting of three-phase AC motors up to 5.5 kW at 400 V
• Motor control centres using compact S00 size equipment
• Reversing and star-delta starter circuits requiring a small-footprint 3-pole contactor
• Load switching in HVAC and building services installations

Compliant with EN 60947-1. Part of the Siemens SIRIUS 3RT2 range.
