For the Cisco uBR7246VXR router, each DC-input power supply rating is 14A, 700 volt ampere

This product relies on the building's installation for short-circuit (overcurrent) protection.
Ensure that a listed and certified fuse or circuit breaker, 35A minimum 60 VDC, is used on all
current-carrying conductors. Site wiring and circuit breakers need to be sized to accommodate
the maximum values for safety reasons.
