Fuse insert AC/DC ETI 002313405 DIII gG 40A 500V with status indicator

ETI 002313405 is a DIII gG fuse insert designed for use in both AC and DC circuits, rated 40 A and 500 V. The insert provides full-range gG protection for general-purpose applications and features a built-in status indicator for quick visual identification of a blown fuse. Engineered for panel and switchgear installation, this fuse insert is suitable for protecting cables, equipment and circuits in industrial and commercial electrical systems where reliable overcurrent protection is required.

Advantages

The fuse insert offers full-range gG protection, combining overload and short-circuit interruption in a single device. Its 40 A current rating and 500 V voltage rating make it compatible with a wide range of AC and DC installations. The integrated status indicator simplifies maintenance by providing immediate visual confirmation of fuse operation without the need for additional testing equipment. The DIII form factor enables straightforward mounting in compatible fuse holders and switchgear assemblies.

Suitable for

• Protection of power cables and distribution circuits in industrial panels
• Overcurrent protection for control and auxiliary circuits in switchgear
• Protection of motors, transformers and general-purpose equipment
• AC and DC systems requiring gG full-range fuse protection
• Applications where fast visual detection of blown fuses is beneficial

Key specifications

• Rated current: 40 A
• Rated voltage: 500 V (suitable for AC and DC applications)
• Characteristic: gG (full-range, general-purpose)
• Type/size: DIII form factor
• Integrated status indicator for visual fault identification
• Intended mounting: panel and switchgear fuse holders
• Typical use: protection of cables, equipment and circuits

How to use

Install the ETI DIII gG fuse insert into a compatible DIII fuse holder or switchgear mounting following the holder manufacturer's instructions and applicable electrical standards. Ensure the circuit is de-energized before inserting or replacing the fuse. Verify that the rated current (40 A) and rated voltage (500 V) match the circuit requirements. After installation, monitor the status indicator to detect blown fuses quickly; when the indicator shows an activated state, de-energize the circuit and replace the fuse with an identical type and rating.

Usage recommendations

Use this fuse insert only in compatible DIII fuse holders and equipment rated for the same voltage and current. Select the fuse rating appropriate to the conductors and devices being protected and follow local electrical codes and safety procedures for installation, testing and replacement. Avoid operating the fuse in environments exceeding the manufacturer's specified temperature and humidity limits and consult technical documentation or a qualified electrician for complex installations.
