Eaton Moeller AFDD Arc Fault Detection Device

AFDD Arc Fault Detection Device

Eaton’s AFDD provides comprehensive protection against
electrical fires triggered by arc faults. This all-in-one
device combines the functions of a residual-current
circuit breaker, miniature circuit breaker, and arc fault
detection, protecting against electric shock, overcurrent,
short circuits, and arc faults. Through continuous electronic
cable monitoring, the device detects arc faults and trips
automatically to reduce the risk of residential electrical
fires. It provides electricians with a more efficient,
standards-compliant solution for enhanced safety.

Core Features:

• Advanced protection: combines arc‑fault detection, overcurrent & short‑circuit protection and earth‑fault (RCCB) functionality.
• Rated breaking capacity 6 kA and 10 kA
• Rated currents up to 40 A
• Tripping characteristics B, C
• Tripping indicators show status and trip cause, saving fault‑finding time
• AFDD busbar as accessory supports easy and flexible installation

Single Module AFDD
Eaton’s single-module AFDD range delivers all-in-one protection in a compact design. Engineered for residential and commercial applications, it enables space-saving distribution boards and seamless upgrades of existing installations, while supporting compliance with BS 7671 AFDD requirements.

Features:

• Arc fault, overload, short circuit & residual current protection
• Only 18 mm width
• 6 & 10kA
• 6 - 40A
• B & C Characteristic
• Type A
• Idn 30mA

Types

• Type -A: Protects against AC and pulsating DC residual currents.
• Type -Li/A: As Type -A, but in addition it is short-time delayed. Highly reliable against unwanted tripping.
• Type -G/A: 10 ms time delay in order to avoid unwanted nuisance tripping (e.g. during thunderstorms).
• Type -F: Higher immunity against smooth DC currents and enhanced surge current proof capabilities.
