Best for

The bypass contactor several 15HP soft starters don't include — it closes only after the motor has already reached full speed, not for direct motor starting.

  • 60A AC-1 / 40A AC-3
  • Normally Open
  • 4-Pole
  • DIN Rail

What is it and what's it for?

A contactor is basically a big remote-controlled switch: a low-current coil (here, 110-120V) closes a set of contacts rated for the equipment's actual heavy current. In a soft starter setup, the bypass contactor has one specific job: once the starter has already brought the motor up to full speed gradually, this contactor closes and lets current flow directly, no longer routing through the starter's electronics — so the starter doesn't have to carry the load around the clock and runs cooler.

Real-world use cases

At home

In a simpler home panel (a 40A contactor for a large water heater or electric oven), this same type of part connects the full load when the thermostat sends the signal, without the thermostat having to handle that current itself.

In a business or workshop

In a 15HP, 240V pump installation with a soft starter (like the one this catalog's VFD guide describes), this contactor wires in parallel with the starter and closes only once the motor is already up to speed — reducing the heat generated inside the panel during the pump's continuous operation.

How to avoid buying the wrong one

  • It's normally open (NO) — confirm you're not accidentally buying the normally closed (NC) version, which serves a different purpose and won't work for this.
  • Its 40A rating is under AC-3 duty (motor starting); for the bypass function what matters is the 60A AC-1 rating, since it closes with no starting load — don't use it to directly start a 15HP motor.
  • It has 4 poles instead of 3 — for a three-phase bypass you use 3 and the fourth is left free (or used for an auxiliary confirmation signal).

The investment takeaway

A bypass contactor with no review history is an expensive gamble in a 15HP panel that runs for hours at a stretch — unlike the generic-brand options ruled out in earlier reviews of this catalog (with no reviews, or just one), this one comes with 39 real reviews and 4.5 stars. The price difference over an untraceable contactor pays for itself the first time it avoids an emergency restart from a contact that stuck or didn't close properly.

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.

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.
