Product Positioning

The 3RT2017-2AP04 is the SIRIUS 3RT20 S00 three-pole contactor with an AC coil. The coil voltage is 230V AC (50/60Hz), and the main circuit AC-3 is rated at 12A and 5.5kW at 400V. It integrates three sets of main normally open contacts and one set of NC auxiliary contacts. The body is slightly deeper than the DC version (45x70x121mm), making it suitable for controlling existing power distribution systems where the power supply is directly taken from 230V AC, eliminating the need for additional transformers or DC power modules.

Core Product Advantages and Features

230V AC coil, no external power supply required

The control power supply can be directly taken from the 230V AC circuit on site, saving the cost and wiring of installing a DC power supply.

3 sets of main normally open + 1 set of NC auxiliary contacts

The main circuit 3NO is equipped with one set of normally closed auxiliary contacts, which is suitable for AC control panel designs that require normally closed interlock signals.

IP20 finger touch protection, wide temperature operating range

The enclosure has an IP20 rating and can operate stably in environments ranging from -25°C to +60°C, making it suitable for most indoor distribution box conditions.

Spring-loaded terminal wiring

The main circuit uses spring clip terminals, allowing for quick on-site installation and subsequent maintenance.
