FAQs

 

What is the primary function of the CB-63CXZ MCCB?

It protects DC circuits up to 80 V and 63 A against overload and short-circuit faults, ensuring the safe operation of power distribution and control systems. 

 

What differentiates the CB-63CXZ from the CB-63CX model?

The CB-63CXZ is designed specifically for DC applications (80 V), while the CB-63CX is built for AC systems up to 415 V. Both share the same compact form factor and reliable thermomagnetic tripping mechanism. 

 

What is the breaking capacity of the CB-63CXZ?

It provides a 10 kA breaking capacity (Icn = Ics), enabling fast interruption of high fault currents to protect downstream equipment. 

 

Can the CB-63CXZ operate in extreme environments?

Yes. It functions reliably between −40 °C and +70 °C, at altitudes up to 2,000 m, with performance derating guidelines available for harsher conditions. 

 

What installation method does it support?

The CB-63CXZ adopts a plug-in installation design with bottom feed connection, providing ease of assembly and maintenance in compact DC panels.
