Frequently Asked Questions

What is the DAYTON IEC Supplementary Protector used for?

The DAYTON IEC Supplementary Protector is a D-curve, 2-pole UL1077 DIN rail-mount device rated at 2 A. It protects industrial control circuits and equipment from overcurrent and short circuits, commonly used in panel building, HVAC, and automation applications where branch circuit protection is not required.

What are the specifications of the DAYTON IEC Supplementary Protector ?

The DAYTON IEC Supplementary Protector has a current rating of 2 A, a breaking capacity of 7.5 kA at 480 V AC, and a voltage rating of 480 V AC. It features a screw clamp connection, D-curve trip characteristic, and is part of the NDB2-63 series. It is not rated for interrupting capacity under UL1077.

Where to buy the DAYTON IEC Supplementary Protector worldwide?

You can source the DAYTON IEC Supplementary Protector through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we provide competitive pricing and reliable sourcing for this DAYTON component.

How to install the DAYTON IEC Supplementary Protector ?

Install the DAYTON IEC Supplementary Protector by snapping it onto a standard DIN rail. Use a screwdriver to tighten the screw clamp terminals to the appropriate torque for your wire size. Ensure the circuit is de-energized before installation. Follow generic best practices for UL1077 supplementary protectors and consult local electrical codes.

Used in

Common applications for DAYTON IEC
Industrial control panels — DAYTON IEC UL489 miniature circuit breakers (e.g., 33V953) for branch circuit protection of motor circuits with high inrush currents.
Commercial lighting systems — D-curve supplementary protectors (e.g., 5ZVF0) to handle inrush currents from lighting loads while providing overcurrent protection.
OEM machinery — 2-pole DIN rail breakers (e.g., 33V920) integrated into equipment for overcurrent protection of control circuits and power distribution.
Panel building — UL1077 supplementary protectors (e.g., 5ZVE4) used downstream of branch breakers to protect sensitive control components.
DC power systems — DAYTON IEC breakers rated for DC (e.g., 33V957) in renewable energy or battery-backed applications requiring 125 V DC protection.
Retrofit projects — Replacement of existing DIN rail breakers with DAYTON IEC models (e.g., 33V953) to meet updated overcurrent protection requirements.
