Integrated with international Hi-tech,SDM6 series moulded case circuit breaker is a new type of circuit breaker which designed by our company. It's compact, modularized, with high breaking capacity, zero-arc, completely environment friendly. SDM6 circuit breaker mainly applies to distribution systems with 50/60Hz, rated voltage up to 690V, rated current 12.5~1600A, its purpose lays in power distributing & protecting system against malfunctions such as overload, short-circuit, undervoltage, etc. it can also work as an infrequent ON/OFF switch under systems working in normal condition.
SDM6 circuit breaker equips with intelligent controller as well, which not only makes its current adjustable but also grants protection against overload(long delay), short-circuit(short delay), shortcircuit(instantaneous) & undervoltage. it'll certainly improve the entire power system's reliability, continuity & security. SDM6 circuit breaker also obtains isolating function.
SDM6 circuit breaker complies to GB14048.2, IEC60947-2 standards, with CCC, CE, TSE
2. Work & Install Circumstance
2.1 Altitude of the installation place shall not exceed 2000m.
