Electrical enclosure accessory Hager MCN120E — AC input 230–400 V

Hager MCN120E — AC input 230–400 V is an electrical enclosure accessory intended to be mounted inside distribution or control enclosures for systems operating on alternating current within the 230–400 V range. The component is designed to integrate with Hager installation systems and provides a compact solution for connecting or adapting AC supply inputs in residential and light commercial installations where this voltage range is used.

Advantages

The accessory offers a compact modular design compatible with standard enclosure mounting, enabling straightforward integration into existing distribution boards. It supports a wide AC input voltage range (230–400 V), which increases compatibility across different local supply standards. The product is produced by a recognized manufacturer of electrical installation components and is intended for professional electrical installation environments.

Suitable for

• Residential distribution boards and main service entries using 230–400 V AC.
• Light commercial electrical panels where a standardized AC input module is required.
• Retrofit projects where an enclosure accessory must match an existing alternating voltage range.

When it may not be suitable

This accessory is not intended for DC systems or for applications that require input voltages outside the 230–400 V AC range. It is not a standalone protective device; if overcurrent protection, earth-fault protection or other specific protection functions are required, separate rated devices must be installed according to local regulations.

Key specifications

• AC input voltage range: 230–400 V.
• Type: electrical enclosure accessory for integration into distribution or control enclosures.
• Application environment: residential and light commercial electrical installations.
• Mounting: modular/enclosure-compatible form factor for standard installation cabinets.

How to use

Install the accessory inside the enclosure following the enclosure manufacturer and local electrical codes. Ensure input wiring is isolated and power is disconnected before making connections. Position the module in the designated mounting space and secure it using the appropriate mounting clips or screws. Make AC input connections according to the system wiring diagram, verify that the supply voltage falls within the 230–400 V range, and restore power only after confirming tight and correct connections. Final commissioning should include verification of correct operation within the larger system and any required protective devices.

What to consider before purchase

• Confirm the system supply is within the 230–400 V AC range.
• Verify physical dimensions and mounting compatibility with your distribution or control enclosure.
• Ensure required protective devices (circuit breakers, RCDs) are provided separately if needed by regulations.
• Check compatibility with other Hager components and overall system wiring diagrams.

Usage recommendations

Use this accessory as part of a complete installation carried out by a qualified electrician. Follow local electrical standards for wiring, earthing, and protective device selection, and perform final testing after installation to confirm safe and correct operation within the 230–400 V AC system.
