Monitoring Relays
1-Phase AC Over Current
Type DIA53R
2
Product Description
Compact current monitoring relay with built-in current trans-
former with adjustable set-point and 5A SPDT AC relay
output. Industrial standard AC power supply for easy use.
12 mm hole for insulate current carrying wire makes it suit-
able for most applications. For mounting on DIN-rail.
17.5 mm wide housing suitable both for back and front
panel mounting.
