Eaton Cartridge Fuse, 31.5A Current Rating, 12kV Voltage - 12BDGNA31.5


This cartridge fuse is an air-insulated medium-voltage protective element designed for use in distribution and primary transformer circuits. It operates on 12 kV AC systems and provides overcurrent protection in applications where a back-up fuse characteristic is required, configured without a striker mechanism for installations that do not need remote triggering.

Features & Benefits


• 31.5 A rated current for stable primary-side protection
• 40 kA interrupting capacity to clear high fault currents
• Back-up characteristic to protect against sustained overloads
• AC service at 12 kV for medium-voltage distribution networks
• Cylindrical form factor for compatibility with fuse holders

**Applications**


• Suitable for primary transformer protection in substations
• Ideal for use in fuse switch combination units
• Used with medium-voltage fuse holders and switches
• Can be used in industrial distribution networks requiring back-up protection

What construction detail ensures compatibility with standard holders?


The element is cylindrical and sized to fit common medium-voltage holders designed for 51 mm-diameter fuse bodies.

How does it behave under fault conditions?


It interrupts prospective fault currents up to 40 kA, allowing Rapid clearing of significant short-circuit events.

What is the expected installation length to account for?


The complete unit measures 375 mm overall, so panel and holder spacing should accommodate that length.

Is a striker pin required for operation in remote systems?


No, this variant is supplied without a striker, so it does not provide mechanical remote trip signalling.
