Product Positioning

The 3RT2017-2AF01 is also an AC coil S00 three-pole contactor with a coil voltage of 110V AC (50/60Hz). Its operating range is 0.8~1.1 times the rated voltage at 50Hz and 0.85~1.1 times the rated voltage at 60Hz. It is equipped with one set of NO instantaneous auxiliary contacts (AC-12 rated 10A, reliability: only one failure per 100 million operations). The main circuit AC-3 is rated at 12A and 5.5kW at 400V, decreasing to 6.7A at 690V. It is suitable for use or expansion of existing panels in 110V AC control power supply systems.

Core Product Advantages and Features

110V AC coil, clearly defined operating voltage range

It can engage normally within a voltage range of 0.8 to 1.1 times the rated voltage at 50Hz and 0.85 to 1.1 times the rated voltage at 60Hz, and is compatible with different power grid frequencies.

1 set of NO auxiliary contacts, high handover reliability

The AC-12 is rated at 10A, and the official specifications state that there is only about one failure per 100 million operations, making it suitable for long-term stable operation.

Lightweight 0.253kg body

The S00 frame is a relatively lightweight coil model, which facilitates high-density panel configuration and handling/installation.

Spring-loaded terminals support various wire diameters.

The main circuit can be connected to solid wire (0.5~4mm²) or stranded wire (0.5~2.5mm²), offering great flexibility in wiring.
