Plastic Switchgear ECH-36PT-S NT 36M 3×12M N+PE IP65 Smoke Door White 1500VDC

Plastic switchgear ECH-36PT-S NT 36M 3×12M N+PE IP65 Smoke Door White 1500VDC is a weatherproof enclosure designed for photovoltaic and electrical installations. The unit provides an NT configuration with space for 36 modules arranged as 3×12M, includes combined neutral and protective earth terminals (N+PE), and is rated for DC systems up to 1500 VDC. Finished in white with a smoke door and rated IP65, the enclosure is intended for string combiner, protection and distribution use in solar arrays and outdoor electrical applications.

Advantages

The enclosure offers IP65 protection against dust and water jets, making it suitable for outdoor installations. Its modular 3×12M layout simplifies component organization and wiring, while the integrated N+PE terminal arrangement reduces the need for separate earthing modules. The smoke door allows visual inspection without full exposure to the elements. Constructed from durable plastic, the switchgear is lightweight, corrosion-resistant and easy to mount.

Suitable for

• String combiner boxes for photovoltaic arrays
• DC protection and distribution in solar farms and rooftop systems
• Outdoor electrical junctions where IP65 protection is required
• Installations needing a compact, modular enclosure with N+PE terminals

When it may not be suitable

This plastic enclosure is not intended for indoor applications that require higher mechanical impact resistance or for environments with continuous submersion. It is also not suitable where metal enclosures are required for specific grounding or electromagnetic shielding needs.

Key specifications

• Enclosure material: plastic (weather-resistant)
• Configuration: NT layout, 36 module positions arranged as 3×12M
• Terminals: combined Neutral and Protective Earth (N+PE)
• Protection rating: IP65
• Door type: smoke (transparent/tinted) door
• Colour: white
• Rated voltage: suitable for DC systems up to 1500 VDC
• Dimensions (approximate external): 535 x 319 x 144 mm

How to use

Mount the switchgear on a flat vertical surface using appropriate fixings for the substrate and the enclosure weight. Install DC combiner modules, fuses, surge protection devices and wiring inside the available 3×12M modular spaces according to applicable electrical standards. Connect the neutral and protective earth conductors to the combined N+PE terminal block. Ensure all cable entries are sealed to maintain the IP65 rating and close the smoke door to protect internal components while allowing visual checks.

What to consider before purchase

• Confirm compatibility with the system voltage and DC rating up to 1500 VDC
• Verify required internal modular space (3×12M) for your protection and combiner components
• Check mounting surface and available space for the enclosure dimensions
• Assess environmental conditions to ensure IP65 protection is sufficient

Usage recommendations

Use qualified personnel for installation and commissioning. Follow local electrical codes when wiring DC conductors and installing protective devices. Periodically inspect seals, cable glands and the smoke door for damage to maintain weatherproof performance.
