Features of Molded case circuit breakers LS ABS series (contains model ABS404c 300A)
Molded case circuit breakers LS ABS series:
- Handle
- Function of indications
- "On" "Off" "Trip"
- Resetting
When the handle indicates "Tripped" position it must first be reset by moving the handle to the "Off" position and then closing is possible
•Trip-free even if the handle is held at "On", the Breaker will trip if an over current flows
•Suitable for verification of the main contact position under abnormal conditions because the handle doesn’t indicate open position
- Arc-Extinguishing unit
LS patent technique PASQ
Arc-extinguishing unit
PASQ : Puffer assisted self-quenching
•Reduction of arc voltage for a short time
- Trip button (Push to trip)
•Enables tripping mechanically from outside, for confirming the operation of the accessory switches and the manual resetting function.
Application: Molded case circuit breakers LS ABS series:A application of PASQ arc extinguishing. -A application of current limiting structure
