## Summary description

Eti-Polam BIWTS fuse cartridge rated 4A, DII size with gF characteristic for full-range protection at 500V. Designed for overcurrent and short-circuit protection in electrical installations and equipment, it provides semiconductor and circuit protection compliant with gF applications. Suitable for distribution boards, industrial control panels and machinery requiring DII gF fusing.

## Long description

Eti-Polam BIWTS 4A DII gF 500V is a fuse cartridge designed to provide full-range overcurrent and short-circuit protection in electrical installations. With a 4 ampere rating and DII (D-type) cartridge size, this fuse features a gF characteristic suitable for protecting both cables and semiconductors at system voltages up to 500 V. The component is intended for installation in distribution boards, industrial control panels and switchgear where reliable coordinated protection is required.
Advantages
The BIWTS fuse cartridge offers precise current interruption for faults while allowing normal operational currents to pass without nuisance trips. Its gF characteristic ensures combined protection of conductors and semiconductor devices, enabling selective coordination with upstream and downstream protective devices. The compact DII size saves panel space and is compatible with standard holders and fuse bases designed for DII cartridges.
Suitable for (tasks / use cases)
Overcurrent and short-circuit protection in distribution boards and control cabinets
Protection of semiconductor devices and power electronics in industrial equipment
Fusing of motor control circuits and machinery supply lines
Use in systems and panels operating at voltages up to 500 V
When it may not be suitable
This fuse cartridge is not suitable where a different breaking characteristic (such as gG or a fast-acting type) is specifically required by the application or standards. It may also be inappropriate for circuits with continuous currents exceeding the 4 A rating or in installations requiring higher voltage ratings than 500 V.
Key specifications
Rated current: 4 A
Fuse size: DII (D-type cartridge)
Characteristic: gF (full-range protection for conductors and semiconductors)
Rated voltage: up to 500 V
Application: overcurrent and short-circuit protection in low-voltage installations
How to use
Install the fuse cartridge into a compatible DII fuse holder or base following the panel or equipment manufacturer's instructions. Ensure the circuit is de-energized and isolated before removing or inserting the fuse. Select the correct fuse based on the required rated current, characteristic, and system voltage. After replacement, verify proper seating and restore power, then check the circuit operation and downstream devices for correct functionality.
What to consider before purchase
Confirm the required rated current and that 4 A matches the circuit protection needs
Verify the gF characteristic is appropriate for protecting both conductors and semiconductors in your application
Ensure the DII cartridge size is compatible with existing fuse holders or panel cutouts
Check that the system operating voltage does not exceed 500 V
Usage recommendations
For coordinated protection, match the fuse with upstream and downstream protective devices and follow applicable wiring and safety standards. Replace blown fuses only with identical-rated gF DII cartridges to maintain intended protection characteristics.
