## Long description

The EMITER EM-749\_AC is a high-performance, hermetic AC switchgear engineered for demanding electrical environments. With an IP65 ingress protection rating, this unit is fully protected against dust and water jets, making it an ideal solution for outdoor installations or industrial settings where equipment is exposed to the elements. It integrates a professional-grade Dehn Type 2 surge arrester to safeguard sensitive electronics from transient overvoltages, alongside a 40A 3-phase configuration and a 63A/300mA Type A RCD for comprehensive leakage current protection.
Advantages
This switchgear provides a robust defense for electrical systems by combining surge protection and residual current monitoring in a single, durable enclosure. The use of a Type 2 surge arrester ensures that the installation is protected against atmospheric discharges and switching surges, significantly extending the lifespan of connected equipment. The IP65-rated housing eliminates the need for additional protective cabinets in many scenarios, simplifying the installation process while maintaining high safety standards. Furthermore, the Type A RCD offers reliable detection of both AC and pulsating DC leakage currents, which is essential for modern electrical setups including solar power inverters.
Suitable for
Solar power system installations
Outdoor electrical distribution points
Industrial machinery power supply protection
Residential and commercial EV charging infrastructure
This unit may not be suitable for environments requiring higher IP ratings, such as areas prone to prolonged submersion or extreme chemical exposure. It is also not intended for use in circuits exceeding its 40A rated current capacity or in applications requiring specialized protection beyond the capabilities of a Type 2 surge arrester.

How to use
The EMITER EM-749\_AC should be mounted on a stable, vertical surface using the provided mounting points. Ensure that the cable entries are properly sealed using appropriate glands to maintain the IP65 rating. Wiring must be performed by a qualified electrician in accordance with local electrical codes, ensuring that the input and output connections are securely tightened to the specified torque. Once installed, the RCD should be tested using the integrated test button to verify correct operation before putting the system into service.
What to consider before purchase
Verify that the 40A current rating is sufficient for your specific load requirements.
Ensure the 300mA RCD sensitivity meets the safety regulations for your particular installation type.
Check the available space at the installation site to accommodate the dimensions of the hermetic enclosure.
Confirm that the Type 2 surge protection is adequate for the lightning risk profile of your location.
Regularly inspect the enclosure for signs of physical damage and perform periodic tests on the RCD to ensure continued safety and compliance with electrical standards.
