PCE Fixed Inlet Socket with Lid 32A 400V 3P+Z+N IP44, model 525-6D

PCE Fixed Inlet Socket with Lid 32A 400V 3P+Z+N IP44, model 525-6D is a stationary industrial power inlet designed to provide a reliable connection for three-phase equipment. The unit supports 32 A current at 400 V with three phases plus protective earth and neutral. Its IP44 protection rating and hinged lid offer splash and light dust protection suitable for indoor environments and sheltered outdoor locations such as distribution panels, temporary power points on construction sites, and machinery inputs.

Advantages

The PCE 525-6D inlet combines a standard three-phase wiring layout with protective earth and neutral for flexible use with common industrial appliances. The hinged lid improves safety by keeping contacts shielded when not in use and contributes to IP44 splash protection. The fixed receiver design enables a secure, permanent installation into panels or enclosures while maintaining easy access for plugging and unplugging cords.

Suitable for

• Permanent installations in distribution panels and switchboards
• Temporary power points on construction sites and events (sheltered locations)
• Power input for industrial machines and equipment requiring 32A three-phase supply with neutral and earth
• Workshops and maintenance areas where a fixed inlet is preferred over portable connectors

When it may not be suitable

This inlet is not intended for permanent outdoor exposure without shelter or for environments requiring higher ingress protection than IP44. It is also unsuitable where a different current rating, voltage, or pin configuration is required, or when a portable connector is preferred instead of a fixed inlet.

Key specifications

• Rated current: 32 A
• Rated voltage: 400 V
• Configuration: 3 phases + protective earth + neutral (3P+Z+N)
• Protection rating: IP44 (splash and limited dust protection)
• Mounting style: fixed inlet / receiver (panel or enclosure installation)
• Protective lid: hinged lid for contact protection when not in use

How to use

Install the fixed inlet into a compatible panel cut-out or enclosure following electrical regulations and manufacturer's mounting instructions. Connect phase, neutral and earth conductors to the corresponding terminals using the correct conductor sizes for 32 A operation. Ensure the lid closes over the inlet when the connector is not in use to maintain IP44 protection. Only qualified personnel should perform wiring and testing; after installation verify tightness of terminals and proper operation with a phase rotation and continuity check before applying load.

What to consider before purchase

• Confirm the application requires a 32A, 400V, 3P+Z+N inlet rather than a different rating or pin configuration
• Check mounting dimensions and panel cut-out compatibility for fixed installation
• Assess whether IP44 protection is sufficient for your site conditions or if a higher IP rating is needed
• Verify wiring standards and conductor cross-section suitable for 32 A circuits in your jurisdiction

Usage recommendations

Use the PCE 525-6D inlet in sheltered or indoor installations and always secure wiring by a qualified electrician. Keep the hinged lid closed when not in use and periodically inspect contacts and seals for wear or damage to maintain safe operation.
