Description
TOAW series Arc fault detection devices (AFDD), is a new generation of circuit breakers, combining fire protection, leakage protection, overload and short circuit protection functions, rated current from 6A to 63A (40-63A model TOAW-63 has 72mm width), The leakage sensitivity is from 10mA to 300mA, it is suitable for single-phase AC circuit, and the operating voltage range is 110V – 240V.
Working principle
The protection units of TOAW-32 consists of followings: arc fault protection and detection unit, modification of unit detection of unit detection and send a tripping signal when distinguishing the fault arc, the tripper pushes the mechanical structure to trip, then the main contact of AFDD will be switched from opening position to disconnecting position, which makes the fault circuit disconnected and avoid efficiently the fire created by arc fault.
Feature:
- Multifunctional protection: personal safety protection, property protection, equipment and appliance protection.
- Small size: 6 – 32A width only needs 36mm, 40 – 63A width only needs 72mm.
- Clear fault indicator for various fault states, it is easy to maintain.
