AKB1-63L

AKB1-63L RCBO is used for the protection against earth leakage in circuit of 50/60Hz,

rated voltage 400V and rated current up to 40A. when somebody gets an electric shock

or residual current of the circuit exceeds fixed value, the NBL 1-40 can cut off the power

with in conventional time automatically and thus ensures personal safety and prevents

equipment from damage resulted from residual current. With this function, the AKB1-63L

can be used for the infrequent switch over of the circuit under normal condition.

This item can be used to protect household and similar installation.

The product conforms to IEC1009-1 standards.
