WSB1-125 series miniature circuit breaker
has advantage of fine and small in size,
light in weight, reliable performance, big
breaking capacity, fast release, rail installation,
with high flame retardant and impact
resistance plastic for frame and parts, and
long service life. It mainly applies in lines of
AC 50Hz or 60Hz, single pole 230V, 400V
for double, three and four poles, for overloading
and short circuit protection, meanwhile in
lighting lines and infrequent on-off electrical
equipments under normal circumstance.
The product meets standards of IEC/EN60947-2,
GB14048.2 at international level.
