Thermal Magnetic Circuit Breaker 1 Pole + Neutral 20A is an automatic switch designed to protect electrical installations against overloads and short circuits. Ideal for homes, businesses, and Indoor cultivation projects, it ensures reliable operation in medium power circuits.

The Magneto-Thermal 1 Pole + Neutral 20A is part of the magneto-thermal automatic switches, in this case from the RV30 REVALCO Series, known for its effectiveness in electrical protection.
Designed to withstand a nominal intensity of 20 amperes, this device automatically disconnects the current when it detects an anomaly, preventing damage to equipment and reducing electrical risks.
Its mechanism integrates thermal protection, which acts against prolonged overloads, and magnetic protection, which responds instantly to short circuits.
Thanks to its compact dimensions, it is easily installed on a DIN rail inside residential, commercial, or technical electrical panels. This magneto-thermal is especially useful in Indoor cultivation environments, where multiple devices such as lamps, fans, extractors, humidifiers, and irrigation systems work continuously. Keeping an installation protected with devices of this type is essential to ensure safety and stability in the system. In addition, it is a component that optimizes the lifespan of connected equipment by preventing damage from electrical failures.
Among the indoor cultivation accessories and tools, the Magneto-Thermal 1 Pole + Neutral 20A stands out as an essential piece that brings confidence and order to any electrical project.
In an Indoor cultivation system, electrical safety is a priority. The Magneto-Thermal 1 Pole + Neutral 20A automatically disconnects phase and neutral when an overcurrent occurs, preventing damage to LED lights, extractors, or irrigation pumps. This level of protection is fundamental in self-cultivation rooms, where humidity and the intensity of equipment use increase the need for a reliable installation.
• Protect electrical circuits against prolonged overloads.
• Disconnect immediately in the event of a short circuit.
• Ensure the proper functioning of equipment in Indoor cultivation.
• Prevent fire risks and damage to electrical installations.
• Ensure the lifespan of lights, extractors, humidifiers, and controllers.
It is a magneto-thermal switch with two poles that combines thermal and magnetic protection in a single device. With a capacity of 20A, it is designed for medium power circuits and is installed in electrical panels with DIN rail. It is part of the RV30 REVALCO Series, certified under international safety standards. This component ensures that the installation is protected against overloads or short circuits, and is essential in cannabis cultivation accessories projects, where reliability in the power supply is required.
1) Install the Magneto-Thermal 1 Pole + Neutral 20A in an electrical panel on a DIN rail.
2) Connect the phase and neutral to the upper inputs of the device.
3) Derive the outputs to the equipment that needs protection, verifying that the total load does not exceed 20A.
4) Test the switch by turning the control lever on and off.
5) Perform periodic checks to ensure that frequent tripping does not occur, as these indicate possible problems in the installation.
