FAQ

What is the correct socket or base for the RHN412B relay?

This relay uses a standard 14-pin socket. A compatible socket from Schneider Electric would be the RXZ E1M or a similar industry-standard 14-pin base.

Can this 24V DC relay be used with a 24V AC supply?

No, this relay is specifically designed for a DC coil voltage. Applying AC voltage will likely damage the coil and cause malfunction.

What is the rated operational current for the contacts?

The contacts are rated for a thermal current of 5 Amperes. It is critical not to exceed this current to prevent overheating and premature failure of the relay contacts.
