MCCB circuit breaker KM1

タイトルまたは説明

KM1 Series Moulded Case Circuit Breaker(MCCB)are suitable for turn-on or turn-off not frequently and starting a motor not frequently in the circuit of AC*0Hz, rated insulation voltage **0V(**0V for KM***3),rated working voltage **0V and below, rated working current up to **0A. The breakers have overload, short-circuit and under voltage protection function, so used in protecting the circuit and the power equipment against damage.

 The MCCB, according to the rated ultimate short circuit breaking capacity (Icu), could be classified four kinds of types C (basic type), L (typical type), M (second high breaking type) and H (high breaking type). The breakers could be installed vertically or horizontally. The breaker has the following features: compact size, high breaking capacity, short arc-over distance (some of is zero arc-over distance), isolating function and shake-proof. They also passed the tests of dirty industry condition(1E grade) and ship condition, become the only product being used in dirty industry base among the same products made in the country, furthermore become the ideal products applied on land or ships.
The breakers comply with IEC******2 and GB****8.2
