Features of Molded case circuit breakers LS ABL series
Molded case circuit breakers LS ABL 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 ABL series have a application of PASQ arc extinguishing /A application of current limiting structure
