Product Description

CNC Ycm1 Series MCCB Circuit Breakers 63A 100A 125A 250A 400A 630A 800A 3p 4p 400V/690V Electric Moulded Case Circuit Breakers

Product Description

YCM1 series moulded case circuit breaker(herein after called circuit breaker) adopts international advanced design and manufactural technology, it can be divided
into L-type (standard type), M-type (higher type)according to the rated ultimate short circuit breaking capacity (Icu). With the features of small and compact, high breaking capacity, short arcing-over distance, anti-vibration, the circuit breaker is used popularly on land and marine products, they are applied for the power distribution network of AC 50Hz,rated insulation voltage 800V (YCM1-63 to 500V), rated working voltage 690V(YCM1-63 to 400V) and below, rated current up to 1250A, it can be used to distribute electric power and protect power equipment against overload, short circuit, undervoltage etc, It also takes protective effect when motors infrequently start and protecting against overload, short circuit and lacking voltage. In the series, frame ranging from 63-630A three-pole product also comes with a transparent cover, it is convenient for customer to observe the product operation.
The circuit breaker can be installed vertically, or horizontally. This product complies with standard of IEC60947-2.


Function and features
Temperature: -5ºC ~+40ºC ; the average value within 24h shall not exceed +35ºC . For the circuit breaker with thermo-magnetic release, +40ºC is set to be the standard temperature for ratings. For temperature not between -5ºC~+40ºC, please contact us for temperature compensation correction;
Altitude: not exceed 2000m (Please contact with us for reduction coefficient if altitude at the mounted site exceed 2000m)
Pollution grade: Grade 3;
Air conditions:
At mounting site, relative humidity not exceed 50% at the max temperature of +40ºC, higher relative humidity is allowable under lower temperature. For example, RH could be 90% at +20ºC, special measures should be taken to occurrence of dews.
