FXBZ7-634P

◆FXBZ7-63PV AC/DC general miniature circuit breaker lreferred as circuit breakerl.It dopt advanced arc strike/arc extinction technology,

current limit technology and fast open/close mechanism can be fast,reliable short circuit current of breaking

◆AC/DC power distribution system,normal rated operating current and critical current /DCl.Tailored for PV DC users it has invention patents).

characteristics are as follows:

◆AC/DC general power distribution,it use non-polar wiring to facilitate user wiring and avoid accidents caused by incorrect wiring of

positive/negative in DC system.

◆It has three phase current limiting copability and provides excellent backup protection.It can greatly limi the l2t value caused by the curren

thermal effect to ensure the power grid maintains low load operation and reduce the damaging of heat effect.

◆ The thermal overload tripping and the electromagnetic overload tripping directly act on transmision mechanism with moving contacts.It

has time delay overload protection and instantaneous protection functions.

◆Position indicate window can instantly and reliably display the exact position of the contacts.The circuit breaker ensures isolate circuit when

the handle is in the OFF position.

◆It can be mounted directly on DIN rail,will not affect characteristics,easy to install and flexible.

◆ It adopt unique magnetic blowing arc extinction device and reliobly break short-circuit current,rated operating current and also reliably

break critical current(DC).

◆Good reliability:Suitable for all possible low voltage DC applications.Such as under 300V AC system and DC trains,DC power grid,

photovoltaic systems,DC communication systems,etc.It can provide reliable protection for reverse current generated by fault photovoltaicstring and the feedback of AC regenerative load of faulty inverter.
