1RU 125A Dual-Feed GMT Fuse Panel
Brand: AmphenolThe Amphenol Network Solutions 125GMT10/nrg125GMT10 and 125GMT15/nrg125GMT15 fuse panels are 125A dual-feed and provide 10/10 and 15/15 GMT fuse positions.
Our 125GMT/nrg125GMT panels feature ±12/±24/±48V operating voltages to serve both legacy and “next-gen” network applications.
Engineered into a standard 1RU footprint that support up to 20A GMT fuses in each position, providing ample capacity for distribution to a broad range of components.
The panel is available in standard terminal block outputs or connectorized outputs.
Features- Universal voltage (±12VDC, ±24VDC, and ±48VDC) enables standardization on a single part number for multiple voltages
- Up to 20A fuses for distribution to a variety of network elements
- UL and NEBS compliant to ensure industry-standard safety and functional requirements
- Form C relay contacts provide reliable alarm connections
- Integrated designation cardholder for simple circuit identification
- Fail alarm LEDs indicate fuse and power failures
- Clear, flame-retardant polycarbonate cover (94V-0) protects input and output power connections and wiring from damage
- Optional Individual Circuit Monitoring provides high accuracy, 100% passive monitoring
- Collect voltage and current for both feed and output circuit
- Collect temperature using optional nrgTEMP probes
