Relay type
- Contacts are open when the coil is unpowered. In the "relay world" this is defined as Form A or SPST-NO (single-pole, single-throw, normally open). Hidden inside the relay are two pairs of contacts wired in series, mechanically linked and operated by a single actuator. This halves the voltage across each pair of contacts which reduces the amount of arcing the instant the contacts open.
- Note: whenever possible do not open contacts under load to avoid DC arcing. If possible deactivate chargers and loads before opening the relay. Conversely before closing the contacts, if there are large capacitors in inverters, etc, use a pre-charge resistor to control charge current to the capacitors thus eliminating the current spike that otherwise occurs the instant the contacts close.
