2-Pole 40A Differential is an electrical protection device designed to detect current leaks and immediately disconnect the installation. With a rated current of 40 amperes and two poles, it provides safety in homes, workshops, and Indoor cultivation systems.

The 2-Pole 40A Differential Switch is manufactured to ensure electrical safety in installations where medium and high consumption equipment is used. Its function is to protect people and the electrical system against current leaks that may cause accidents or damage to devices.
With a nominal capacity of 40A and two poles, it covers both phase and neutral, disconnecting both conductors in case of leakage, which increases the reliability of the protection.
This type of differential switch is essential in indoor growing projects, where lights, extractors, fans, humidifiers, climate controllers, and water pumps are used. The use of multiple devices connected simultaneously requires a high level of protection to ensure the continuity and safety of the installation.
Thanks to its compact design, it can be installed in standardized electrical panels with DIN rail, integrating alongside circuit breakers and other control devices.
Its use also extends to offices, homes, and commercial premises, becoming an essential component within indoor growing accessories and tools and any modern electrical installation. By incorporating a 2-Pole 40A Differential Switch, the risk of overheating, electric shocks, and equipment damage is reduced, providing peace of mind to the user and complying with safety regulations.
In an indoor growing system, having a 2-Pole 40A Differential Switch ensures that any current leakage is detected immediately, disconnecting the installation before accidents occur.
This level of protection is indispensable in grow rooms, where humidity, irrigation, and high-performance electrical equipment coexist. Integrating a differential switch in the electrical panel guarantees order, reliability, and safety throughout the self-cultivation process.
• Protect people against electric shocks caused by current leaks.
• Immediately disconnect phase and neutral in the event of an electrical fault.
• Prevent fires due to cable overheating or earth faults.
• Integrate safety in electrical panels of homes, workshops, and indoor growing.
• Complement circuit breakers for complete electrical protection.
It is a differential switch with 2 poles and a nominal current of 40A. Its main function is to interrupt the current when it detects leaks to earth, protecting both people and connected equipment. Unlike a circuit breaker, which protects against short circuits and overloads, the differential switch acts against unwanted current losses, being an essential element in any safe electrical installation. It is mounted on a DIN rail and easily integrated into electrical panels for cannabis growing accessories, offices, and homes.
1) Install the 2-Pole 40A Differential Switch in an electrical panel on a DIN rail.
2) Connect phase and neutral to the upper inputs, and route the outputs to the rest of the installation.
3) Check the correct grounding of the installation to ensure the effectiveness of the device.
4) Regularly press the test button (TEST) to check the correct operation of the differential switch.
5) Make sure not to exceed the nominal current of 40A and combine it with suitable circuit breakers.
