Fuse Insert ETI 002313402 — AC/DC gG DIII 50 A 500 V with Status Indicator

ETI 002313402 is a replaceable fuse insert designed for protection of AC and DC circuits. Rated as gG DIII, it provides general-purpose overcurrent protection at 50 A and up to 500 V. The unit features a built-in status indicator that allows quick visual verification of fuse condition during inspection or maintenance. The design is intended for panel-mounted and switchgear installations where a compact, serviceable fuse solution is required.

Advantages

The fuse insert combines general-purpose gG characteristic protection with DIII physical size compatibility, ensuring interchangeability with existing holders of the same type. The included status indicator reduces the need for electrical testing to determine faulted elements and speeds up maintenance and replacement. Its construction supports both AC and DC applications, enabling flexible use across different circuit types and reducing the need for multiple fuse variants.

Suitable for

• Panel-mounted distribution and protection circuits
• Switchgear and control cabinets
• Industrial machinery power circuits requiring 50 A protection
• DC and AC branch circuits where visual fuse status is needed

Key specifications

• Rated current: 50 A
• Rated voltage: 500 V
• Breaking characteristic: gG (general-purpose)
• Physical/size class: DIII
• Built-in visual status indicator for fuse condition
• Suitable for both AC and DC circuit applications

How to use

Install the ETI 002313402 fuse insert into a compatible DIII fuse holder or panel-mounted carrier, ensuring the holder is de-energized before insertion. Verify correct orientation and seating in the holder so the status indicator remains visible for inspection. Replace the fuse insert with one of the same rated current and type after a cleared fault; follow standard safety and lockout procedures when servicing. Confirm circuit de-energization and proper reinstallation before restoring power.

Usage recommendations

Use this fuse insert in holders and equipment rated for DIII-size gG fuses and verify compatibility with both the system voltage and the 50 A rating. Periodically inspect the status indicator during maintenance intervals and replace any unit that shows a blown indication. For systems with mixed AC and DC loads, ensure the overall installation practice and protective coordination meet applicable standards and wiring regulations.
