Frequently Asked Questions

What is the DAYTON IEC Supplementary Protector used for?

The DAYTON IEC Supplementary Protector is used for overcurrent protection in industrial control panels, HVAC equipment, and lighting circuits. Its B-curve trip characteristic makes it suitable for resistive and light inductive loads where inrush currents are low. It mounts on a standard DIN rail and is UL1077 listed for supplementary protection.

What are the specifications of the DAYTON supplementary protector?

The DAYTON is a 20 A, 1-pole supplementary protector with a B-curve trip characteristic. It has a maximum AIR rating of 5kA at 277V AC and an AC voltage rating of 277V AC. The terminal connection is screw clamp, and it is part of the NDB2-63 series. It is not rated for DC voltage.

Where to buy the DAYTON supplementary protector worldwide?

You can source the DAYTON supplementary protector through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations.
