NOFUEL 3RT1034‑1AK61 AC Contactor

Product Description

NOFUEL 3RT1034‑1AK61 is an S2‑frame 3‑pole AC power contactor fully dimension‑compatible with Siemens 3RT1034‑1AK61, designed for frequent start‑stop control of three‑phase AC motors and resistive industrial loads under AC‑3 duty cycle. It provides rated operational current of 32 A with matching motor power of 15 kW at 400 V, fitted with built‑in 1NO auxiliary contact for running‑status signal feedback. This contactor uses screw‑type terminals, supports 35 mm DIN rail and direct screw mounting, features IP20 front‑side touch‑protection and CE compliance. Its control coil is rated 110 V 50 Hz / 120 V 60 Hz, widely applied in pumps, fans, machine tools and medium‑size automation panels as a cost‑effective drop‑in replacement for the original Siemens unit.

Standard Features

• Full mechanical interchangeability: Matches S2 housing dimensions, terminal layout and mounting hole positions of Siemens 3RT1034‑1AK61 for direct replacement without cabinet modification.
• 3‑pole anti‑arc main contacts: Alloy main contacts resist arc erosion for reliable repeated motor switching under AC‑3 operating conditions.
• Integrated 1NO auxiliary contact: Factory‑fitted normally‑open auxiliary contact for interlock logic and equipment status signal output.
• Fixed 110/120V AC control coil: Coil rated 110V 50Hz / 120V 60Hz, matching widely‑used North‑American and Asian industrial control supplies.
• Dual mounting capability: Supports snap‑on installation to standard 35 mm DIN rail as well as surface screw mounting for flexible cabinet layout.
• IP20 operator safety: Insulated front terminal cover prevents accidental contact with live conductive parts during maintenance work.
• Extended mechanical service life: Optimized electromagnetic structure enables high‑cycle performance for continuous industrial operation.
