    SMCM1L-225H/4300 Molded case circuit breaker Applications and functions

    • Incoming and outgoing function in distribution systems Switching and protection devices for motors, transformers and

    Disconnect or units with feai an emergency mechanisms with ld<eabte rotary operating Avail^le in the following Power protection: the

    designed for the protection of cables, leads and non-motor loads Motor protection: the overload and sh<xt-circut retaases are designed for optimized protection and direct-on-Hne starting of induction squirrel-cage motors. The circuit breakers for motor protection are susceptible to phase failure and feature an adjustable trip class

    • There Is no frame E and F for motor protection.

    1 Only M type (medium breaking capacity type) has 4 poles:

    4A: N-poie fixed without over-current release unit, it has been connected all atoog, and does not act with other three poles to turn on or off.

    4B: N-pole fixed without over-current release unit, it acts with other three poles.

    4C: N-poie fixed with over-current release unit, it acts with other three poles.

    4D: N-poie fixed with over-current retease unit, it has been

    Ked all adong, and does not act with other

    Attitude

    The rated perfornoance of the circuit breaker does not change up to 2000 meters. Beyond this altitude, the performance of the circuit breaker is subjest to derating, s

    Temperature

    Storage: -40°C to +70°C Operating: -5°C to +40°C

    In case the drcuit breaker operates at higher temperatures than +40°C, the current-carrying capacity of the circuit breaker may be lower than the rated current-carry capacity at the reference temperature, therefore the derating coeffrcients must be applied, see the derating coeffictents table on page A/00.

    Relative humidity

    When maximum temperature is 4〇°C, relative humidity shall be less than 50%.

    When the temperature is relative low, the relative hu巾idlty is allowed to be higher.

    Condensation caused by change of temperature shall be taken special measures.

    Installation category Main circuit: III

    ^jxiliary circurt and control circuit: II Installation environment

    Horizontal or vertical, maximum inclination: 22.5 °.

    Resistance to moist air. satt mist and oil mist.

    Installed in an environment which is not enough to erode the metal or to destroy the insulating gas and without explosive danger. Installaed in an environment without attack from rain and snow.

    Applications and functions

    • Protection of plant and equipment against overload or damage by ground faults (ground-fault protection)

    Protection against tire hazard caused by insulation faults Switching and protection devices for motors, transformersar>d capacitors
