Product overview:
One, the application range of the NS series moulded case circuit breaker is one of the new type circuit breaker this company adopts the international advanced technology research and development, its rated insulation voltage of 950V, applicable to AC 50Hz or (60Hz), rated voltage 690V and below, current rated current 12.5A to 630A, for the distribution of electricity, do not frequently closed under normal conditions and disconnected with, and play a protective role in the line and the equipment overload, under voltage. Rated frame size current in 400A and circuit breaker below, can also be used as a squirrel cage motor is not frequent starting, running off and in the motor overload, short circuit and under voltage protection works. Products comply with GB14048.2, IEC60947.2 standard. Two, category 1, according to the installation mode is divided into: vertical, horizontal loading; 2, by use of circuit breaker: distribution and protection, motor protection type; 3, according to the mode of connection points: front plate connector, wiring on back of the board, insertion type wiring; 4, according to the operation mode: direct manipulation, handle external turning handle operation, electric operation; 5, press release type: only the instantaneous tripping device (electromagnetic release), thermal and electromagnetic trip (double), electronic release; 6, according to very few points: diode, triode, tetrode; quadrupole circuit breaker, neutral (N) there are four kinds of type: A type: N is not installed over current tripping device, and N is always on is not with the other pole together; B: N is not installed over current tripping device, and the N pole and the other pole together; C type: N pole mounted over current release, and the N pole and the other pole together; D type: N pole mounted over current tripping device, and N is always on, not together with other pole; has the inverse time characteristic of circuit breaker tripping characteristic thermodynamic release three, circuit breaker; electromagnetic tripper for instant action (distribution) have (protection of electric Machine is shown in table two and table three).
