# Relay rating explanation

Let say we have a relay rated for 12 VDC - 80 A

This relay is connected to a 4 Ω load and a 300 VDC power supply (charged capacitor) for a few milliseconds. The current in this case is 75 A.

My question is: when the voltage of the circuit exceeds the voltage rating of the relay but not the current rating, will this damage the relay?
