Best for

The available option in this BAOMAIN family for both small loads (since the 16A one was discontinued) and medium loads — and the one with the most real buyer track record if you'd rather not risk a brand-new listing.

  • 20A
  • 110V AC coil
  • 166 reviews

What is it and what's it for?

It's the same type of "big relay" as the other contactors in this ranking: it separates the small control (a smart switch, a thermostat, a PLC) from the actual current a heavy device draws, so the control doesn't burn out handling that load directly.

Real-world use cases

At home

Automating a water heater, a pump, or a medium-consumption lighting fixture, without the smart switch or thermostat having to handle the device's full current.

In a business or workshop

A shop or store that needs to automatically control a 20A device (small motor, heating element, commercial lighting) can use this contactor as a safe intermediary between the control and the load.

How to avoid buying the wrong one

  • It's AC only — doesn't work for DC, per the manufacturer's own note.
  • Doesn't include built-in short-circuit protection — always install it with a separate fuse or breaker.
  • Confirm your equipment's real amperage: if your load is small (lighting, a minor water heater), this 20A model costs the same as the smaller option that's no longer available; if your load is well above 20A, check the higher-amperage contactors elsewhere in this same catalog.

The investment takeaway

With 166 reviews versus the 1-2 of other new listings in this catalog, this is the option with the most real backing — at the same price as always, the buyer track record is extra assurance that costs nothing more, and today it's also the only one of this specific family still in stock.

Waveshare RS232/485/422 to Ethernet Gateway (PoE)

RS485/ModbusPoEDIN rail
4.2 · 120 reviews

Supports all three serial standards (RS232/485/422) on one device, so it works for both old instruments with an RS232 port and multi-device RS485 buses. PoE power is a real plus in installations where there's no outlet near the panel — a single Ethernet cable carries both data and power. Confirm whether your Modbus master needs TCP Server or Client mode before buying; the mode is set in software, it doesn't come fixed from the factory.

#2MOLLOM VFD 1.5kW (2HP) — Single-Phase to Three-Phase 220V

MOLLOM VFD 1.5kW (2HP) — Single-Phase to Three-Phase 220V

220V 1P→3P2HPCNC
4.1 · 31 reviews

Single-phase input to 220V three-phase output — the typical choice for workshops without a three-phase feed that want to run a 3-phase motor. This is an entry-level model (2HP/1.5kW), meant for spindles and small CNC motors, not large industrial loads. The output range up to 3000Hz is only useful if your specific spindle takes advantage of it — for a standard 60Hz motor it's irrelevant.

#3VFD 4kW (5HP) Vector Control — 220V 1-Phase/3-Phase

VFD 4kW (5HP) Vector Control — 220V 1-Phase/3-Phase

Vector control5HP1P/3P
4.3 · 24 reviews

Has vector control (not just scalar V/F), which holds torque better at low RPM — important if you'll be threading or cutting at reduced speed. At 5HP/4kW it covers larger motors than the entry-level model, and accepts both single-phase and three-phase input, giving flexibility depending on the electrical setup available. Rated up to 26A — confirm your wiring and breakers can handle that current before installing.
