What stands out about the build is the General-Electric signature on the plastic housing.
GE 750 Feeder Management Relay 750-P5-G5-S5-HI-A20-R-E with SR750 Case (001950)
what stands out about this piece is the Potter badge, which looks like it will last.
You will find that Zaplyte relays are easy to handle and quick to wire up.
I like thatING brand sits neatly on the relay without any smudging or odd spacing.
