Arc Fault Detection Devices (AFDD)
Compare VIOX VAF1-40 and VAF3-40M devices for combined arc-fault, Type A residual-current, overload and short-circuit protection in 240V AC final circuits.
- 6–40A · B or C characteristic
- 1P+N · 6kA
- IEC/EN 62606 · IEC/EN 61009-1
Four protective functions in one final-circuit device.
The catalog combines arc-fault detection with three familiar circuit-protection functions. Each function addresses a different fault condition.
আর্ক-ফল্ট সনাক্তকরণ
Monitors current signatures associated with hazardous arcing conditions.
Type A residual current
Responds to sinusoidal AC and pulsating-DC residual-current conditions within the declared sensitivity.
ওভারলোড সুরক্ষা
Provides the published B or C overcurrent tripping characteristic for sustained overcurrent.
শর্ট-সার্কিট সুরক্ষা
Interrupts short-circuit current within the device’s declared 6kA rating.
Choose the VIOX AFDD version.
Both models share the published protection range. Select the construction version, then confirm the exact current, characteristic and residual-current sensitivity.
Compare VAF1-40 and VAF3-40M.
The electrical values below reproduce the shared VIOX catalog. The catalog identifies VAF3-40M as the magnetic version.

Why arc faults require a dedicated detection function.
Some hazardous arcs may not create the high current expected from a conventional short circuit. An AFDD evaluates current behavior for arc signatures while the integrated overcurrent and residual-current functions continue to address their own fault categories.
Read the IEC 62606 guideTypical final-circuit applications.
Use the project design and applicable installation rules to determine where AFDD protection is required or appropriate.
আবাসিক ফাইনাল সার্কিট
Socket-outlet and other final circuits where combined arc-fault, residual-current and overcurrent protection is specified.
বাণিজ্যিক স্থান
Offices, shops and similar installations with final circuits that require the declared combined protection functions.
Concealed wiring routes
Circuits where damaged conductors, loose connections or insulation deterioration can be difficult to inspect directly.
Fire-risk assessment
Projects where the electrical design identifies arc-fault mitigation as part of the fire-protection strategy.
Build a complete AFDD order specification.
Do not select the device from “40A AFDD” alone. Confirm every rating and the destination-market document set.
Ask VIOX to review a specification- 01
Choose the model version
State VAF1-40 or the VAF3-40M magnetic version.
- 02
Confirm the current and curve
Select 6–40A and the required B or C characteristic for the circuit.
- 03
Confirm residual-current sensitivity
Specify the required Type A 10mA or 30mA configuration.
- 04
Verify installation conditions
Check voltage, frequency, prospective short-circuit current, conductors, torque and circuit length.
- 05
Request exact documents
Match the model, rating, destination market, labeling and required declarations before release.

AFDD selection FAQ.
Model-level answers based on the current shared product catalog.
What protection is integrated into the VAF1-40 and VAF3-40M?
The published catalog describes both models as AFDDs with integrated Type A residual-current, overload and short-circuit protection. They are intended for 240V AC, 50Hz final circuits within the declared ratings.
What is the main difference between VAF1-40 and VAF3-40M?
The VAF3-40M is identified as the magnetic version. The current catalog publishes the same main electrical range for both models: 6–40A, B or C tripping characteristics, 10mA or 30mA residual-current sensitivity, 1P+N and 6kA short-circuit rating. Confirm construction and project-specific requirements with VIOX before ordering.
Can an AFDD replace every protective device in a circuit?
No single device should be assumed to satisfy every system requirement. The VIOX models combine several stated functions, but final selection, coordination and installation must follow the exact product data, circuit design and applicable rules.
Which standards are listed for these AFDD models?
The shared catalog lists IEC/EN 62606 and IEC/EN 61009-1. Documentation must be confirmed for the exact model, rating and destination market before specification or private-label approval.
What information should I send for an AFDD quotation?
Provide the preferred model, rated current, B or C characteristic, 10mA or 30mA residual-current sensitivity, quantity, destination market, required documents and any OEM marking or packaging requirements.
