IDEC POWER RELAY RH4B-U DC24V 4 POLES RH SERIES 10A W/ SOCKET SH4B-05 10A 300V

What stands out about the Potter & Brumfield version is the simple cover and easy to identify pins.

You will find that the Songle brand is familiar, and that familiarity can make testing and setup feel calmer.

The LY2N Relay IEC255 uses standard spade terminals, which I find convenient when making quick field connections without special tools.

This relay and socket set is simple to mount, and the connections feel secure once you plug everything in.
