Plastic Switchgear ECH-48PT-S NT 48M 4x12M N+PE IP65 Smoke Door White 1500V/DC

Plastic switchgear enclosure ECH-48PT-S NT 48M 4x12M N+PE IP65 Smoke Door White 1500V/DC is a purpose-built housing for solar and DC electrical installations. It is configured as a 48-module (48M) distribution box arranged as 4 rows of 12 modules, with dedicated space for neutral and protective earth conductors. The enclosure is rated IP65 for dust-tight and water-resistant protection and is suitable for mounting DC breakers, surge protection devices and wiring used in photovoltaic arrays rated up to 1500 V DC.

Advantages

The enclosure offers a compact, pre-configured layout that simplifies installation of DC protection components and cable routing. The IP65 protection class ensures reliable operation in outdoor or semi-exposed locations by preventing ingress of dust and water jets. Its white housing with a smoked transparent door allows visual inspection of installed devices without opening the cabinet, and the plastic construction reduces weight while providing electrical insulation and corrosion resistance compared with metal alternatives.

Suitable for

• Photovoltaic combiner and protection stations for solar rooftop and ground-mounted systems
• DC distribution and surge protection installations up to 1500 V DC
• Locations requiring a corrosion-resistant, lightweight enclosure with visual access via a smoked door
• Installations that need separate accommodation for neutral and protective earth conductors

When it may not be suitable

This plastic enclosure may not be appropriate where metal enclosures are required for mechanical impact resistance, enhanced electromagnetic shielding or where local regulations mandate metallic equipment. It is not intended for AC distribution above the specified DC voltage rating or for environments requiring higher ingress protection than IP65.

Key specifications

• Configuration: 48-module (48M), arranged as 4x12M
• Material: durable plastic enclosure with smoked transparent door
• Protection class: IP65 (dust-tight, protected against water jets)
• Conductor provision: dedicated N+PE accommodation
• Voltage rating: suitable for DC systems up to 1500 V DC
• Color: white housing with smoked door

How to use

Mount the enclosure on a suitable flat surface or mounting structure following local installation rules and manufacturer mounting recommendations. Fit the DIN-rail mounted breakers, surge protection devices and terminal blocks into the 4x12 module layout, and route DC positive, negative and N+PE conductors to the designated terminals. Ensure correct torque on terminal connections, maintain appropriate clearances, and seal cable entry points consistent with the IP65 rating. Verify system polarity and insulation before energizing and follow all applicable safety standards for photovoltaic DC installations.

What to consider before purchase

• Confirm compatibility with module and string current ratings as well as breaker and surge device dimensions
• Verify that a plastic enclosure meets local mechanical, fire and regulatory requirements for your installation
• Ensure the IP65 rating and mounting options suit outdoor exposure and cable entry arrangements
• Plan for ventilation, heat dissipation and conductor routing in high-current DC applications

Usage recommendations

Use the enclosure for organized DC protection assemblies in PV systems up to 1500 V DC, install surge protection close to the array, keep positive and negative conductors separated and secure N and PE connections per local earthing practices. Regularly inspect seals and the smoked door for integrity and clean the exterior to maintain visual inspection capability.
