Compliance with standards
International standards:
IEC 947-1: General (GB/T 14048.1);
IEC 947-2: Circuit Breaker (GB/T 14048.2);
IEC 947-4: Contactors and Motor Starters (GB/T 14048.4);
IEC 947-5.1: Control Devices and Switches; Automatic Control Element(GB/T 14048.5);
GB 14048.1 General;
GB 14048.2 Circuit Breaker
National Standards:
Hot and Humid Measure
FNT9M Circuit Breakers and auxiliary devices T2 hot and humid conditions, comply
with the following standards:
IEC 68-2-30 At 45 degrees Celsius,95% relative humidity (wet mat to heat and weather);
IEC 68-2-11 Salt Spray Test
Isolation
All FNT9M Circuit Breakers are suitable for isolation, comply with the standard IEC 947-2:
Contact isolated position in the "0" (OFF position);
Unless the contact is fully open, operate slot can not be "OFF" position;
contacts are open state license before they can install a padlock;
lnstallation of extended rotary handle does not change the reliability of the position
indication system.
lsolation has assurance testing Guarantee:
The reliability of mechanical contact is ensured by the position indication system;
No leakage current;
Overvoltage tolerance refers to the ability of withstanding voltage between its inlet
and outlet.
Installation of class ll switchboards
Circuit Breakers should be installed in all FNT9M class ll switchboards (according to
IEC 664 standard);
No special installation operation, because FNT9M circuit breaker provides class ll
panel and all insulation of internal circuits.
Cable entry
FNT9M online outlet into the next lower usage, no need to consider derating (except FNT9ML). This feature will provide greater convenience
to the switchboards installation
