Series Overview
Series Overview
● CM5 Molded Case Circuit Breakers (hereinafter referred to as circuit breakers) are a new generation of circuit breakers developed with internationally advanced technology using a double-break structure.
● The thermal-magnetic adjustable type CM5 series circuit breakers have seven frame size ratings: 63A, 125A, 160A, 250A, 400A, 630A, and 1600A, with currents ranging from 1.5A to 630A. Among these, the 125A and 160A frame sizes have a C-type short-circuit breaking capacity level which is thermal-magnetic fixed type; the L-type has both thermal-magnetic fixed type and adjustable type, with currents ranging from 1.5A to 160A.
● CM5-250, 400, and 630 circuit breakers can be used with busbar adapters to achieve integrated quick installation and connection.
● Circuit breakers are classified into seven levels based on rated ultimate short-circuit breaking capacity (Icu): C-type (Basic), L-type (Standard), M-type (Higher Breaking), H-type (High Breaking), S-type (Ultra High Breaking), V-type (Extreme High Breaking), and R-type (690V High Performance).
● Circuit breakers with short-circuit breaking capacity levels C, L, M, H, and S can be reverse connected at all voltage levels. V and R types cannot be reverse connected at AC690V voltage.
● Circuit breakers can be mounted vertically or horizontally on vertical mounting plates, or mounted on horizontal mounting plates.
● All circuit breakers have isolation function, indicated by the corresponding symbol: ●
● Products comply with the following standards:
● IEC 60947-1 and GB/T 14048.1-2012 Low-voltage switchgear and controlgear - General rules
● IEC 60947-2 and GB/T 14048.2-2008 Low-voltage switchgear and controlgear - Circuit-breakers
● IEC 60947-3 and GB/T 14048.3-2017 Low-voltage switchgear and controlgear - Switches, disconnectors, switch-disconnectors and fuse-combination units
● IEC 60947-4-1 and GB/T 14048.4-2010 Low-voltage switchgear and controlgear - Contactors and motor-starters - Electromechanical contactors and motor-starters (including motor protection devices)
Application Occasions
● Low-voltage Distribution Protection
● CM5 distribution type circuit breakers can be used in AC50/60Hz TN, TT, IT distribution systems, meeting the requirements for "Selection of Electrical Apparatus" in GB50054.
● CM5's reliable contact indication and isolation function meet the requirements for isolation devices in GB50054.
● Motor Circuit Protection
● CM5 motor protection type circuit breakers provide overcurrent protection for motor starters, cables, and motors. Their protection characteristics meet GB14048.4, and their application meets GB50055.
● Residual Current Protection
● Operating time meets the requirements for graded coordination in GB13955.
● Provides residual current protection solutions for AC690V.
● Switching Function
● Two CM5 circuit breakers equipped with a mechanical interlock can achieve manual switching between two power sources for the same equipment or between two pieces of equipment on the same power source.
● Two circuit breakers with mechanical and electrical interlocks, equipped with controllers, etc., can achieve automatic switching between two power sources.
Normal Service and Mounting Conditions
● Ambient air temperature: -5°C to +40°C;
● Altitude at the installation site does not exceed 2000m;
● Relative humidity of the air at the installation site does not exceed 50% at a maximum temperature of +40°C. Higher relative humidity is permissible at lower temperatures, e.g., 90% at 20°C. Special measures should be taken for occasional condensation due to temperature changes;
● Pollution Degree: 3;
● Circuit breakers meet the requirements of GB/T 2423.10 and can withstand mechanical vibration with frequency 2Hz~13.2Hz, displacement ±1mm, and frequency 13.2Hz~100Hz, acceleration ±0.7g;
● Installation category of the main circuit: III; Installation category of other auxiliary and control circuits: II;
● Circuit breakers are suitable for electromagnetic environment A;
● Tropical humid type (TH type) circuit breakers meet the requirements of GB/T 2423.4 and GB/T 2423.18, and can withstand the effects of humid air, salt mist, oil mist, and mold;
● Circuit breakers should be installed in locations without explosion hazards, conductive dust, or conditions sufficient to corrode metal and destroy insulation;
● Circuit breakers should be installed in locations free from rain and snow intrusion;
● Operable Conditions:
● Circuit breakers meet the requirements of GB/T 2423.1 and GB/T 2423.2; ambient air temperature can be as low as -25°C and as high as +70°C (derating applies above +40°C, see technical data in this catalog);
● Circuit breakers meet the requirements of GB/T 2423.4 Test Db (temperature +55°C, relative humidity 95%);
● Characteristics unaffected up to an altitude of 2500m (derating applies above 2500m, see technical data in this catalog);
● Storage Conditions: Ambient air temperature: -25°C to +70°C.
