Thermal Magnetic Circuit Breaker 1 Pole + Neutral 25A Narrow is an automatic electrical protection switch designed for residential, commercial, and Indoor cultivation installations. Compact, reliable, and easy to integrate into electrical panels, it guarantees safety against overloads and short circuits.

The Thermal Magnetic Circuit Breaker 1 Pole + Neutral 25A Narrow is a device from the Revalco brand, made of bakelite and with a compact design of 36 mm that facilitates its integration into electrical panels with limited space.
Rated current is 25 amperes and it supports voltages up to 400V, making it an ideal solution for medium-high consumption circuits. This circuit breaker combines two protection mechanisms: the thermal system, which reacts to prolonged overloads, and the magnetic system, which acts immediately in the event of short circuits. Thanks to this double safety, damage to electrical equipment is avoided, the installation is protected, and accident risks are reduced.
It is especially recommended for Indoor grow rooms, where high-power lighting equipment, ventilation systems, extractors, water pumps, and climate controllers are used.
Maintaining a stable power supply in these environments is essential, and this type of indoor grow accessories and tools become key components.
In addition, the narrow format allows for neat mounting on a DIN rail, ensuring efficiency and space optimization within the electrical panel. Its construction with resistant materials provides durability, making it an essential component within cannabis grow accessories and any modern installation.
In Indoor grow projects, it is essential to have devices that guarantee safety in the power supply. The Thermal Magnetic Circuit Breaker 1 Pole + Neutral 25A Narrow fulfills this function by automatically disconnecting the circuit when an overload or short circuit is detected. Its compact 36 mm design makes it perfect for panels with limited space, ensuring order and reliability in professional installations. This type of accessory is fundamental to protect both climate and lighting equipment and the integrity of the electrical installation.
• Protect electrical circuits from prolonged overloads.
• Automatically interrupt the flow of current in the event of short circuits.
• Ensure the stability of electrical equipment in Indoor grow.
• Prevent failures in lights, fans, extractors, or water pumps.
• Keep installations safe in homes, businesses, and cannabis grow accessories.
It is a bipolar thermal magnetic circuit breaker of narrow type that protects both the phase and the neutral of an electrical circuit. With a nominal capacity of 25A, a maximum voltage of 400V, and construction in bakelite, it ensures durability and reliability. Its operation is based on two tripping systems: the thermal, which is activated by continuous overloads, and the magnetic, which reacts instantly to short circuits. Thanks to its reduced size of 36 mm, this component can be easily installed on DIN rails in compact electrical panels, being an essential element within indoor grow accessories and tools.
1) Install the Thermal Magnetic Circuit Breaker 1 Pole + Neutral 25A Narrow in an electrical panel with a DIN rail.
2) Connect the phase and neutral to the device inputs, ensuring a correct fit.
3) Route the outputs to the electrical equipment you want to protect, such as LED lamps, extractors, or irrigation systems.
4) Check that the total consumption of the equipment does not exceed 25A.
5) Use the switch lever to turn the power supply on or off as needed.
6) Periodically check the operation to ensure there are no recurring trips, which may indicate a problem in the installation.
