Fuse cartridge Eti-Polam BiWts 35 A DIII gF 500 V, type 002313101

Eti-Polam BiWts 35 A DIII gF 500 V is a cylindrical fuse cartridge designed for overcurrent and short-circuit protection in industrial and commercial electrical installations. With a rated current of 35 A, gF characteristic and DIII size, this fuse provides full-range protection for both conductors and main circuit components at voltages up to 500 V. It is intended for use in compatible DIII fuse holders and distribution systems where selective breaking and coordinated protection of downstream equipment are required.

Advantages

The fuse cartridge offers reliable breaking performance for both overloads and short circuits thanks to its gF characteristic, which combines conductor protection and full-range interruption capability. Its standardized DIII form factor ensures mechanical compatibility with common holders and panels. Rated for 500 V systems, the unit supports a wide range of industrial and commercial applications. Construction and rated current provide predictable thermal and short-circuit behaviour for easier coordination with upstream protection devices.

Suitable for

• Protection of distribution lines and feeder circuits in commercial or light-industrial panels
• Protecting cable runs and wiring against overcurrents and short circuits
• Motor circuit protection when coordinated with appropriate protection and starting devices
• Use in panel-mounted fuse holders and switch-disconnect units designed for DIII cartridges

When it may not be suitable

This fuse is not intended for use in systems requiring lower or higher rated voltages than 500 V or in circuits needing time-delay or highly selective characteristics that differ from gF. It may be unsuitable for installations where space, form factor or special approvals (for example specific regional certifications) are required and not provided.

Key specifications

• Rated current: 35 A
• Breaking characteristic: gF (full-range, conductor protection)
• Size/format: DIII cartridge
• Nominal voltage rating: 500 V AC
• Application: overcurrent and short-circuit protection for cables, motors and distribution lines

How to use

Select a compatible DIII fuse holder or switch-disconnector rated for the same voltage and current. Ensure the circuit is de-energized before inserting or replacing the fuse cartridge. Install the fuse into the holder with correct orientation and secure the holder according to the panel manufacturer's instructions. After replacement, verify continuity and restore power following applicable safety and commissioning procedures. Coordinate the fuse rating and characteristic with upstream and downstream protection devices to achieve the desired selectivity.

What to consider before purchase

• Confirm the required rated current (35 A) and that a gF characteristic is appropriate for the application
• Verify compatibility with existing DIII fuse holders and panel mounting dimensions
• Ensure the 500 V nominal voltage rating matches system voltage and installation standards
• Check coordination with upstream protection to maintain selectivity and system safety

Usage recommendations

Use this fuse as part of a coordinated protection scheme: pair it with correctly rated upstream devices, and replace only with identical type and rating to preserve intended protection characteristics. Always follow local electrical codes and safety procedures when installing or servicing fuses.
