EMITER EM-47N_AC Hermetic AC Surge Arrester Type 1+2, 10A 3-Phase, IP65

The EMITER EM-47N_AC is a professional-grade hermetic AC surge arrester designed to safeguard sensitive electrical equipment from voltage spikes and transient surges. Utilizing advanced Noark Type 1+2 protection technology, this device is engineered for 3-phase electrical systems with a 10A current rating. Its robust construction is housed within an IP65-rated enclosure, providing complete protection against dust ingress and water jets, making it an ideal solution for outdoor installations and harsh industrial environments.

Advantages

This surge arrester offers a comprehensive safety solution by combining high-performance surge suppression with a durable, weather-resistant design. The integration of Type 1+2 protection ensures that both high-energy lightning strikes and smaller switching surges are effectively diverted, protecting downstream infrastructure. The hermetic IP65 housing eliminates the need for additional protective cabinets in many outdoor scenarios, simplifying installation and reducing overall project costs while maintaining high reliability in demanding conditions.

Suitable for

• Solar panel electrical installations
• Outdoor electrical distribution boxes
• 3-phase industrial power systems
• Infrastructure requiring protection against atmospheric discharges

When it may not be suitable

This device is specifically rated for 10A 3-phase systems and is not suitable for applications exceeding this current capacity. It should not be used in environments where the voltage requirements fall outside the specified operational range of the internal surge protection components.

Key specifications

• Protection type: Noark Type 1+2
• System compatibility: 3-phase AC
• Rated current: 10A
• Ingress protection rating: IP65
• Design: Hermetic enclosure

How to use

The device should be installed by a qualified electrician in accordance with local electrical codes. It is typically mounted in series or parallel with the incoming power supply, depending on the specific system configuration. Ensure that the enclosure is securely fastened to a stable surface and that all cable glands are tightened to maintain the IP65 hermetic seal. Proper grounding is essential for the surge arrester to function correctly and divert excess energy safely to the earth.

What to consider before purchase

• Verify that your system current does not exceed 10A
• Ensure the 3-phase configuration matches your electrical infrastructure
• Confirm that the IP65 rating meets your specific environmental exposure requirements

Usage recommendations

Regularly inspect the surge arrester status indicators and the integrity of the enclosure seals to ensure continued protection. If the internal protection module has been triggered by a significant surge, it should be replaced immediately to maintain system safety.
