Fuse insert KOMBI NH00 160A gG/gL 500V WT-00 by Eti-Polam

Eti-Polam KOMBI NH00 fuse insert WT-00 is a 160A gG/gL cartridge rated for 500V designed for use in NH00 fuse holders. This low-voltage protective element provides overcurrent protection for distribution and industrial circuits and is intended for general-purpose circuit protection and selective coordination in compatible switchgear. The cartridge style and standard NH00 dimensions make it suitable for replacement in systems that accept KOMBI-type inserts.

Advantages

The fuse insert offers time-tested gG/gL characteristics for full-range protection of conductors and equipment against overloads and short circuits. Its 160A rating combined with 500V maximum voltage allows use across many low-voltage distribution applications. The KOMBI format is compatible with NH00 holders, facilitating straightforward replacement and maintenance while maintaining standard safety and protection levels expected in industrial and commercial installations.

Suitable for

• Low-voltage distribution panels and feeders requiring 160A protection
• Industrial machines and motor circuits where general-purpose fuse protection is needed
• Selective coordination schemes in switchgear using NH00 insert cartridges
• Maintenance and replacement in systems that use KOMBI NH00 fuse holders

When it may not be suitable

This fuse insert is intended for general-purpose gG/gL protection and is not designed for protection of highly selective electronic loads that require fast-acting or semiconductor-protective fuses. It may also be unsuitable where a different breaking capacity, different time-current characteristic, or a voltage rating above 500V is required. Verify the required type and characteristic before replacing fuses in sensitive or nonstandard installations.

Key specifications

• Rated current: 160 A
• Rated voltage: up to 500 V
• Fuse characteristic: gG / gL (general purpose)
• Format: KOMBI NH00 cartridge
• Application class: low-voltage overcurrent protection for distribution and industrial circuits

How to use

Install the KOMBI NH00 fuse insert into a matching NH00 fuse holder according to the holder manufacturer's instructions and local electrical codes. Ensure the circuit is de-energized and isolated before removing or inserting the cartridge. After fitting, verify correct seating and secure any retaining mechanisms. Replace only with the same rated current and characteristic to maintain protection coordination and avoid equipment damage.

What to consider before purchase

• Confirm NH00 holder compatibility and available space for KOMBI cartridges
• Ensure 160 A and 500 V ratings match system requirements and coordination studies
• Check whether a gG/gL general-purpose characteristic is appropriate for the protected equipment
• Verify required breaking capacity and local regulatory or safety standards

Usage recommendations

Use this fuse insert as part of a coordinated protection scheme; when replacing fuses, match both current rating and characteristic to the original specification, and inspect holders and contacts for wear or corrosion during maintenance to ensure reliable operation.
