What stands out about the 4016819 is how the terminals accept solid and stranded wire comfortably.
NEW ZETTLER AZ733-2C-12DE RELAY 12V 12VDC COIL
When you unbox a Dayton relay, you will find that the terminals are clean and easy to attach.
A nice touch is the AMERICAN ZETTLER / MCE branding on the relay, giving it a familiar, reliable look.
The TE Connectivity name is right there, and that alone can make a difference when you install it.
You will find that this unbranded relay is light but sturdy, making it easy to mount without extra brackets.
A nice touch is the Potter & Brumfield date code, which helps with traceability during maintenance.
What stands out about this relay is the Songle label, which seems to match what other builders report.
The Potter & Brum are crisp, and the part number is easy to read on the body.
You will find that this power relay suits both small boxes and larger panels with ease.
The WD3556 is the one we and it matches the diagrams quite well.
