The plastic fuse holder LD047 from Hager is a 3-pole fuse holder for D01 fuse inserts with a rated voltage of 400 V and a rated current of 16 A. It is specifically designed for mounting on DIN rail and serves for protecting electrical circuits in installation and distribution applications in residential and utility buildings. The holder features an integrated frame terminal and a cover, ensuring a safe, clear, and standard-compliant installation. The plastic construction is halogen-free, REACh-SVHC-free, and RoHS-compliant, supporting its use in modern electrical installations.

Applications

The fuse holder LD047 is intended for use in electrical distributors and installation systems, particularly in residential and utility buildings. It enables the protection of circuits with a nominal voltage up to 400 V and a nominal current of 16 A. Mounting on DIN rail (spacing 35 mm) allows for standardized and modular integration into existing control systems. Its use in distributors and enclosures is especially suitable due to its compact design and integrated frame terminal.

Functions and Equipment in Detail

The holder is designed for D01 fuse inserts (E14) operated at a rated current of 16 A. The integrated frame terminal enables a secure and reliable connection for conductor cross-sections from 1.5 to 35 mm². The connection type is via a cage terminal, designed for flexible conductors. The cover provides a closed and protective finish for the holder, enhancing safety during operation. The rated voltage of 400 V and rated current of 16 A are suitable for typical low-voltage applications in building environments.

Technology Explained Simply

The fuse holder LD047 is made of plastic and offers high insulation performance. The integrated frame terminal ensures a stable and durable connection to the conductor, requiring a torque between 2.5 and 3 Nm. The cover protects against accidental contact with the terminals and increases operational safety. The D01 form factor is a standard size for fuse inserts, widely used in many distributors and enclosures. The frequency specification of 50 Hz corresponds to standard grid frequencies in Europe.

Compatibility and Accessories

The holder is compatible with D01 fuse inserts (E14) with a rated current of 16 A. As suitable accessories, the screw cap LE14SK (D01 E14 ceramic) is offered, enabling additional protection and visual identification. The use of this screw cap is optional and serves to improve identification and safety of the fuse inserts.

Mounting and Installation

Mounting is done on a DIN rail with a spacing of 35 mm. The integrated frame terminal allows for easy and secure connection to the conductor. Conductor cross-sections from 1.5 to 35 mm² are designed for flexible conductors. Mounting requires a torque between 2.5 and 3 Nm to ensure a reliable connection. The cover is placed after installation to protect the holder and enhance safety.

Operational Advantages

The fuse holder LD047 provides safe and clear circuit protection. The integrated frame terminal and cover increase safety and prevent accidental contact. The use of halogen-free plastic and compliance with RoHS and REACh-SVHC contribute to environmental compatibility. The D01 form factor and DIN rail mounting enable modular and standardized integration into existing systems. The rated voltage of 400 V and rated current of 16 A are suitable for typical applications in residential and utility buildings.
