Quoting an MRT-3 engineer, Transport Undersecretary for Rails Cesar Chavez said that 'a misaligned arc chute
touched the electrical box of the line contactor.'
The C-Series employs a unique arc chute
design, which allows for higher interrupting capacities of up to 10,000 amps.
If an event occurs, arc pressure builds and opens a flap and the arc flash energy enters an arc chute
. The arc chute
forms a mechanical maze lengthening the flame path causing it to go through flame arresting vents.
