Industrial Relays 199 Open Style Power Relay / DPDT, 40 Amp Rating
The maximum switching voltage of a relay is the maximum voltage that can be across the contacts whether the relay is open or closed. Operating a relay with high voltages present can cause arcing, and this in turn erodes the contacts and eventually degrades contact performance.
A current coil is basically a coil, such as, a wire wrapped around an electrical conductor.
