MGL Avionics ECB

Electronic circuit breaker module

This flexible module provides up to 8 individual circuit breakers that can be configured for trip currents up to 10A. Breaker doubling and tripling options allow for trip currents of up to 30A.

This module can operate completely stand alone and does not require any form of external device such as an EFIS system or laptop computer for configuration – however, using an MGL EFIS does extend the configurability to detail level.

Connected EFIS systems can show breaker states, control breakers and reset faulted breakers. Alarms can be issued on a faulted breaker. The EFIS can also show the individual current flowing through each breaker.

Up to 8 of these modules may be used in a single, connected system giving up to 64 usable breakers.

Advanced functionality includes landing light “wigwag” (alternate flashing of landing lights) as well as strobe implementation able to drive high brightness LED lamps directly.

The ECB implements a highly robust and fault tolerant design allowing full use of latest “high side” semiconductor switches with built in protection circuits and devices making them effectively indestructible.

Owing to low cost the ECB for the first time presents a viable alternative to old fashioned mechanical breakers while greatly enhancing reliability of the aircraft electrical system and allowing decentralized power distribution. It is no longer required to bring high current wiring to the panel.
