External And Installation Size
advantage
Our MCCBs provide you unmatched circuit protection in alternative
energy, commercial, industrial, mining, and military applications
when protecting conductors against overloads and short circuits.
These circuit breakers are applied in panelboards, switchboards,
motor control centers, control panels, combination starters,
individual enclosures, and bus duct plug-in units.
The breakers according to the rated maximal value to short- circuit
breaking ability (Icu), would be classified four kinds types C
(basic type), L (typica1 type), M (second high breaking type) and H
(high breaking type). The breakers are of the following
characteristics: compact size, high breaking ability, short
arc-over distance (some of the "0" arc-over distance) and shake
proof. They also undergo the tests of nuclear industry conditions
(1E grade) and ship conditions, and become the only product using
in nuclear industry base among the same products made in the
country, further more become the ideal products applied on land or
ships.
Matters need attention
Normally, we will provide the most suitable shipment method for
you. If the quantity is few, the goods will be sent by express when
the payment is clear. Also, we can transport the goods by air or by
sea, just according to your demand
