Best for

120V panels with a neutral that need a breaker + ground fault + surge protection in a single module — double-check the diagram if you're energizing without a neutral.

  • GFCI 30mA
  • DIN rail
  • 20kA

What is it and what's it for?

This breaker combines three protections in a single module: it cuts power if there's an overload (like a regular breaker), cuts power if it detects a leak to ground (for example if someone touches something faulty — this is the GFCI), and absorbs surge spikes like the ones from a lightning storm.

Real-world use cases

At home

It protects a home panel (for example, a garage workshop) against three different risks with a single device, instead of buying three separate protections.

In a business or workshop

An industrial panel in a wet environment (laundry room, outdoors) needs this triple protection to avoid both equipment damage and electrical risk to people.

How to avoid buying the wrong one

  • Several reviews (including one that ended in a fire) report the wiring instructions are confusing for 208V/240V without a neutral — double-check the diagram for your installation before energizing it.
  • The protection rating is IP20 (not sealed) — it only works inside an enclosed panel, not directly exposed to the outdoors.
  • Comes with 1 DIN rail and 5 crimp terminals included, so you don't need to buy those parts separately.

The investment takeaway

Buying a breaker, GFCI protection, and surge protection separately costs more and takes up more panel space — this combined module saves money and space, as long as you wire it correctly per the right diagram for your voltage.

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.

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.
