NOFUEL 3RT1045‑1AK60 Power Contactor

Product Description

The NOFUEL 3RT1045‑1AK60 is a drop‑in replacement 3‑pole power contactor matching the S3‑frame footprint of the original Siemens SIRIUS contactor. Optimized for AC‑3 category three‑phase motor and resistive load switching, this device works with 110 V 50 Hz / 120 V 60 Hz AC control coil and adopts screw‑type wiring terminals. It supports standard 35 mm DIN‑rail installation inside electrical cabinets and is widely used in motor starters, pump control, conveyor systems and general factory‑automation load‑switching applications.

Standard Features

• 3‑pole main contact structure: Designed for three‑phase motor and resistive‑load switching operations.
• AC‑3 utilisation performance: Adapted for frequent motor start‑stop cyclic working conditions.
• Drop‑in replacement footprint: S3 frame dimension allows direct field substitution for original equipment.
• Screw‑type terminal connection: Provides secure and maintainable wiring for industrial cabinet environments.
• DIN‑rail compatible mounting: Supports fast installation on standard 35 mm DIN mounting rails.
• Dual‑frequency coil support: Operates stably under 110 V 50 Hz or 120 V 60 Hz control supply voltage.
• Expandable auxiliary contacts: Allows additional auxiliary contact blocks for signal feedback functions.
