Product Description
Sdm7 Series Motor Protection Circuit Breaker (32A)
1. Application Area
SDM7-25 series moulded case circuit breaker mainly applies to power systems of AC690V, 50Hz, rated current ranged from 0.1~32A, its purpose lays in protection against overload, phase defect, short-circuit, etc. under 3-phase rotor cage induction motor system, it also can work as infrequent ON/OFF switch and isolator.
SDM7-25 approves CCC, CE, TSE certificate.
2. Working Circumstance
2.1 Altitude of the install place shall not be higher than 2000m.
2.2 Circumstance temperature shouldn't be higher than +40ºC, or lower than -5ºC.
2.3 Relative humidity shall not be higher than 50% when temperature at the highest +40ºC. Average humidity of the most humid month shall not exceed 90%, while average temperature of this month shall not be lower than 25ºC.  
2.4 Pollution class: 3.
2.5 Install type: II, III(load class & distributing class)
2.6 Inclination between install plane surface and vertical plane surface shall not exceed ±5°.
2.7 Working system: uninterrupted type.
3. Working Theory & Structure Characteristics
SDM7-25 circuit breaker is an integrated equipment which includes the functions of isolator, breaker, thermal relay, etc. it can effectively protect power system from malfunctions as overload, phase defect, temperature compensation, short-circuit, etc.
SDM7-25 circuit breaker complies to GB14048.2, GB14048.4, IEC40947-2, IEC60947-4-1 standards.
SDM7-25 structure: connected to main circuit through thermal components, while motor suffers from overload, the bimetallic strip inside got heated up to trigger the circuit breaker to break off.
When motor suffers from phase defect, the bimetallic strip of this phase would cool down and recover its shape, by differential device's enlarging effect, circuit breaker would break off. While current reach the limit of instantaneous electromagnetic trip, magnetic core acts at once, forcing lever to cut off the current while driving operating module to trip, making circuit breaker to break off.
SDM7-25 breaker is in consist of bottom foundation, contact support, arc-chute, insulating base, thermal-magnetic system(including instantaneous electromagnetic tripping unit, bimetallic strip, thermal components, etc.), differential device, current adjusting device, operating module, product cover, push button and so on.
SDM7-25 breaker adopts flip-over direct-acting type double contacts structure, contact bridge, contact support & arc-chute are installed in the bottom foundation, thermal-magnetic system, static contact, operating module, differential device, current adjusting device are installed on base. There is a breaking test function, toggle the handle inside the "test" column according to the printed arrow to make sure the overload tripping function is reliable.
