Circuit breaker overview
Usage and scope of application
The IZM6 series intelligent general-purpose circuit breakers (here-
after referred to as circuit breakers) are a new-generation of high-
performance air circuit breakers with advanced technology and
comprehensive functions, thus offering safety and reliability. The
circuit breakers are suitable for use in power distribution network
with AC 50/60Hz, rated operating voltage of up to 1140V AC, and
rated operating current of 6300A and below, to distribute elec-
tric energy and protect electric lines and power equipment from
potential hazards due to overload fault, under-voltage fault, short-
circuit fault, ground fault, and current imbalance fault. The circuit
breakers offer a variety of protections using multi-functional intel-
ligent controllers with precise selectivity protection, among which
the PXR4 and PXR6 intelligent controllers can be equipped with
optional communication interfaces, easy to connect the field bus
to offer four remote functions including "remote measurement",
"remote adjustment", "remote control" and "remote communica-
tion" to meet control automation requirement. When equipped
with residual current transformer and matching intelligent control-
lers, the circuit breaker can also offer residual current protection.
Circuit breakers with the rated current of 1000A and below can
also be used in power networks of AC 50/60Hz and 400V to
protect motors against overload, short circuit, undervoltage and
ground faults. Under normal conditions, they can be used for
infrequent motor starting.
The products have passed national compulsory product certifica-
tion with CCC mark.
The circuit breakers feature isolation function, with the symbol as
“
