Fuse cartridge Etipo ETI Polam WT00C 004181213 gG 80A 500V KOMBI (time-delay)

Etipo ETI Polam WT00C 004181213 is a gG-type fuse cartridge rated for 80 A and 500 V with KOMBI time-delay characteristics. It is intended for general-purpose circuit protection in industrial and commercial electrical panels, providing protection against both overloads and short circuits while allowing brief transient currents to pass without nuisance tripping. The cylindrical cartridge format fits standard fuse holders and switchgear designed for low-voltage protective elements.

Advantages

This fuse cartridge combines gG (general purpose) breaking characteristics with KOMBI time-delay behavior to balance short-circuit interrupting capacity and tolerance to start-up or inrush currents. Its rated voltage and current make it suitable for many low-voltage distribution and motor feeder circuits. The construction conforms to common industrial form factors, enabling straightforward replacement and maintenance in existing installations.

Suitable for

• Protection of distribution circuits in commercial and industrial switchboards
• Protection of motor feeders and circuits with moderate inrush currents
• Replacement of general-purpose low-voltage cartridge fuses in panels designed for cylindrical fuses
• Applications requiring delayed-action protection to avoid nuisance trips during short transients

When it may not be suitable

This fuse is not intended for use in high-voltage systems above its 500 V rating or in applications that require fast-acting fuses for sensitive electronic equipment. It may not be appropriate where selective coordination with other protective devices requires a different characteristic or where extremely fast clearing of faults is necessary.

Key specifications

• Type: gG (general-purpose) with KOMBI time-delay characteristic
• Rated current: 80 A
• Rated voltage: 500 V (AC)
• Format: cylindrical fuse cartridge for compatible fuse holders and switchgear
• Function: protection against overloads and short circuits with tolerance to transient inrush

How to use

Ensure power to the circuit is isolated before attempting replacement. Verify the fuse holder and panel are designed for a cylindrical gG cartridge with the same rated current and voltage. Insert the fuse cartridge firmly into the holder and secure any retaining clips or covers. After replacement, restore power and confirm proper operation of the protected circuit. Periodically inspect the fuse holder and surrounding wiring for signs of overheating or corrosion.

What to consider before purchase

• Confirm the fuse holder compatibility and physical dimensions match the cylindrical cartridge format
• Verify that 80 A and 500 V ratings meet the circuit's steady-state and maximum voltage requirements
• Consider whether KOMBI time-delay characteristics suit the equipment (motors, transformers, inrush conditions)
• Check coordination with upstream and downstream protective devices to ensure selectivity

Usage recommendations

Use this Etipo ETI Polam gG 80 A 500 V KOMBI fuse cartridge where robust general-purpose protection with limited time-delay is needed. For circuits with sensitive electronics or where instantaneous clearing is required, choose a fuse with appropriate fast-acting characteristics or consult an electrical engineer for coordination studies.
