🚀 Why CNC AFDD Is the Smart Choice

Comprehensive Arc Fault Detection
Detects series arcs (in the same conductor) and parallel arcs (between conductors) — the two most common electrical fire causes.
Integrated Protection Modules
Combines MCB (overcurrent), RCD (residual current), and AFDD into a single device for full circuit safety.
Fast Disconnection
Rapidly interrupts faulty circuits within milliseconds once a dangerous arc is detected.
Status Indication & Diagnostics
LED indicators or status flags let you easily monitor the health of your circuits.
High Surge Withstand & Immunity
Able to handle transient surges and ignore benign arcs (e.g. from motors or switches).
Compliance with International Standards
Designed per IEC / EN AFDD standards for global compatibility and safety assurances.
Compact & Modular Design
Fits standard DIN-rail systems; scalable for residential, commercial, or industrial installations.

🛠 FAQ — CNC AFDD (Arc Fault Detection Device)

Q1: What exactly is an AFDD, and how does it differ from an MCB or RCD?
An AFDD identifies dangerous arc faults (e.g. caused by damaged wires, loose connections, aging insulation) and disconnects the circuit. MCBs protect against overcurrent/surge, and RCDs protect against earth leakage. CNC’s AFDD combines all three protections in one device.

Q2: Where should AFDDs be installed?
Fault Arc Protector are recommended for bedrooms, living rooms, kitchens, circuits with cables hidden in walls or ceilings, circuits supplying appliances, or where fire risk is high. In many countries, building codes now require AFDDs in new residential builds.

Q3: Does CNC AFDD ever produce nuisance tripping?
High-quality CNC AFDDs are designed to discriminate benign arcs (like those from switches or motors) from dangerous ones. But proper sizing and installation reduce the chance of nuisance tripping.

Q4: What is the lifespan of AFDD devices?
Under normal conditions, CNC Fault Detection Devices are designed to operate reliably for 20+ years, subject to proper electrical environment and regular inspections.

Q5: Can I retrofit AFDD into my existing breaker panel?
Yes — if your panel has free space and compatible busbar / DIN-rail. Ensure the new AFDD’s rating matches or exceeds the existing circuit demands.

Q6: What is the warranty and support from STCMart?
All CNC AFDDs supplied via STCMart come with official manufacturer warranty, plus dedicated technical support for installation, diagnostic help, and after-sales care.

Q7: How do I choose the right model or rating?
Consider the load current (amps), number of poles, and whether your system is single-phase or three-phase. If in doubt, contact our team — we’ll guide you based on your building’s wiring and load profile.
