NOFUEL 3RT1017-1AK61 AC Contactor 3-Pole 12A AC-3 5.5kW 400V 110V/120V Coil S00 Frame Replacement for Siemens 3RT1017-1AK61

Product Description

NOFUEL 3RT1017-1AK61 is a S00-frame 3-pole AC contactor fully interchangeable with Siemens 3RT1017-1AK61, engineered for frequent on-off control of three-phase AC motors and resistive industrial loads under AC-3 duty cycle. It delivers a rated operational current of 12 A with a matching motor power of 5.5 kW at 400 V, equipped with a built-in 1NO auxiliary contact for equipment running signal feedback. This contactor adopts screw terminal wiring, supports standard 35mm DIN rail and direct screw mounting, features IP20 front touch safety protection, and complies with CE certification. Its control coil is rated 110 V 50 Hz / 120 V 60 Hz, widely applied in machine tools, ventilation fans, conveyor equipment and compact control cabinets as a cost-effective substitute for discontinued original Siemens contactors.

Standard Features

• Full mechanical interchangeability: Identical S00 housing dimension, terminal layout and installation hole position with Siemens 3RT1017-1AK61 for direct plug-and-play replacement.
• Stable 3-pole main contact system: Three normally open main contacts with alloy material to resist arc erosion for frequent motor switching.
• Integrated 1NO auxiliary contact: Factory pre-installed single NO auxiliary contact for circuit interlock and operation status signal output.
• Fixed 110/120V AC control coil: Coil rated at 110V 50Hz / 120V 60Hz, matching North American and Asian industrial control power supply standards.
• Dual mounting design: Supports snap-on assembly on 35mm DIN EN rail and independent screw fixing to adapt diverse cabinet layout demands.
• IP20 insulation protection: Insulated front terminal cover prevents accidental contact with live conductive parts during maintenance work.
• Long mechanical service life: Optimized electromagnetic structure realizes up to 30 million mechanical switching cycles for long-term continuous operation.
