Industrial switch with thermal protection for 220V motors
This AC-3 thermal overload relay switch ensures the safety of electric motor equipment by automatically shutting them off in case of overload. Ideal for concrete mixers, pumps, slicers, and other industrial machinery, it prevents motor burnout by quickly disconnecting power during excessive current. The professional solution for equipment under heavy use.
What you get with this product
- Automatic motor protection — the thermal relay disconnects power before the motor suffers permanent damage
- Save on costly repairs — avoid winding burnouts and motor replacements
- Resistance to harsh conditions — IP55 casing protects against dust and water splashes
- Simple screw-in installation — mounts directly on the electrical panel or machine housing, no complex modifications needed
- Reliable operation under high loads — supports up to 16A in AC-3 mode, suitable for industrial motors
- Large, easy-to-operate buttons — visible and safe on/off switching, even with protective gloves
How it works and how to install it
The switch is mounted on the machine's electrical panel, connected in series with the motor. The green button starts the motor, and the red one stops it. The thermal relay constantly monitors the current: if it exceeds the safe value, the relay automatically disconnects the power, protecting the motor from overheating. Installation requires electrical knowledge — connect the terminals according to the diagram in the manual, secure with the included screws, and test operation. No special maintenance is required after installation.
Frequently asked questions
At what current does the thermal protection trip?
The relay is calibrated to automatically disconnect at 15-16A, depending on the duration of the overload, protecting the motor before damage occurs.
Can I use it outdoors?
Yes, the IP55 protection makes it resistant to dust and water splashes, but mount it in an electrical enclosure if directly exposed to the elements.
Do I need to reset anything after the protection trips?
Yes, after tripping, press the red button completely to reset, then restart the machine with the green button.

Inspired to create a chair where the backrest and armrests are molded from a single piece of plywood
Inspired to create a chair where the back and arms are moulded from a single piece of plywood, Hecht and Colin describe employing a process similar to that a tailor might use to cut a pattern in fabric. This approach resulted in the beautiful structure wherein the moulded back and arms component is supported by a simple A-frame wood dowel construction. One of the benefits of this design is an increase in comfort due to natural movement in the plywood back.
