3RT20151AP043MA0

The S00 frame 3-pole contactor has been modified to use a 230V AC 50/60Hz coil, screw terminals, and factory-fixed 2NO+2NC auxiliary contacts, making it suitable for direct replacement of existing distribution boxes with only AC power.

Product Positioning

The 3RT2015-1AP04-3MA0, like the aforementioned -3MA0 series, belongs to the 2NO+2NC fixed auxiliary contact model. However, the coil has been changed from 24V DC to 230V AC with a frequency of 50/60Hz, making it one of the few AC operating coil versions in this batch. This means that if only a 220~230V AC control power supply is available on-site and a 24V DC power supply is lacking, this model can be directly used to replace the DC version, saving the cost and wiring of additional transformers or power modules. The main circuit specifications remain 3-pole 3NO, AC-3 rated 7A, approximately 3kW at 400V, and screw-type terminals. After checking data from multiple distributors (eBay distributors, electricautomationnetwork), the 2NO+2NC auxiliary contact configuration is consistent with the AC 230V coil. However, the power values indicated on some platforms (such as 1.15kW) do not match the mainstream data of 3kW/400V. It is judged that this is due to different operating conditions or incorrect configuration. Therefore, this page adopts the 3kW/400V that has been consistently confirmed from multiple sources.

Core Product Advantages and Features

230V AC 50/60Hz coil

The coil is designed for AC 230V and is compatible with 50Hz and 60Hz power grids, making it suitable for the common voltage environments in Taiwan and export markets.

No additional DC power supply required

Compared to DC coil models in the same series, this model can directly use the existing AC control power supply, reducing the cost and wiring of adding a 24V power supply.

2NO+2NC fixed auxiliary contacts

It comes with 4 sets of auxiliary contacts built in, which can meet multiple control needs such as self-holding, interlocking and signal feedback, eliminating the need to purchase auxiliary contact sockets separately.

Screw terminal S00 miniaturization

Continuing the S00 minimum frame design, and equipped with screw terminals, it is suitable for control box configurations with limited space but still requiring AC coil operation.
