10 bar three-phase pressure switch for compressors The pressure switch is the brain of the compressor : it starts the motor when the pressure drops and stops it when the tank reaches its maximum pressure. If yours doesn't cut out, won't start or has burnt contacts, this is its replacement.
A 10 bar three-phase pressure switch with built-in thermal protection , in three ranges according to motor power: 2-3 HP , 3-5.5 HP and 4-7.5 HP .
✅ Key benefits
Automatic control: starts and stops the compressor according to pressure.
Thermal protection: protects the motor against overloads.
Three power ranges: choose the one that matches your motor.
10 bar: the usual maximum working pressure for workshop compressors.
Direct replacement: for three-phase piston compressors.
🏗️ What it's for
Replacing the faulty pressure switch of a three-phase compressor.
Belt-driven compressors from 2 to 7.5 HP.
Building compressors and air units.
Compressor maintenance workshops.
📋 Technical specifications
Voltage: three-phase
Maximum pressure: 10 bar (145 psi)
Ranges: 2-3 HP (3-6 A) · 3-5.5 HP (6-10 A) · 4-7.5 HP (10-16 A)
Protection: built-in thermal
Unloader valve: not included
💡 Pro tip: choose the range by the motor current (check its rating plate) and not just by HP. Before touching anything, disconnect the power and drain the tank ; if you have no experience with three-phase installations, have an electrician fit it.
🔧 How to get the most out of it
Choose the amp range that matches your motor's rating plate and leave the connection to an electrician.
Frequently asked questions
Which model should I choose?
The one that matches the power and current of your motor: 2-3 HP (3-6 A), 3-5.5 HP (6-10 A) or 4-7.5 HP (10-16 A).
Is it suitable for single-phase compressors?
No, it is three-phase. For single-phase units we have 4-way pressure switches.
At what pressure does it cut out?
It is designed for compressors up to 10 bar.
Does it have an unloader valve?
It does not include an unloader valve.
Can I install it myself?
If you have electrical knowledge, yes; if not, we recommend a professional, as it works at 400 V.
