Product details

1. Description Of NS Series Moulded Case Circuit Breaker:

NS Moulded Case Circuit Breaker (NS, MCCB) is one of products developed and manufactured by adopting international advanced technology. It is supplied with rated insulating voltage 550 and 800V and used for circuit of AC 50/60Hz, rated operating voltage AC 400V (or below), rated operating current up to 1600A for infrequent changing over and starting of the motors. The products conforms to IEC60947-2 standard.


2. Working Environment

♦ The altitude bellows 2,000m;

♦ Circuit breaker may be used between -25℃ and +70℃. For temperatures higher than 40℃ (65℃ for circuit breakers used to protect motor feeders), devices must be derated;

♦ It can withstand the impact from humid air, salt spray, oil mist and mold;

♦ In places with no rain and snow erosion.

1). Overload protection with adjustable threshold, as defined by IEC60947-4 (2) tripping class 10A,10 and 20;

2). Short-circuit protection with adjustable threshold (6...13 xIr);

3). Phase failure protection;
4). Fault indication.

LEDs indicates the type of fault that caused tripping;

Overload (LT protection) or abnormal component temperature (>Ir);

Short-circuit (ST or instantaneous protection) (>Im);

Phase failure (right LED);

Microprocessor malfunction ( (>Ir) (>Im) and phase failure LEDs all go on)

Battery powered. Spare battery are supplied in an adapter box. When a fault occurs ,the LEDindicating the type of fault, lights for about 10 minutes . The information is however stored inmemory. The LED can be illuminated by pressing the test pushbutton. The LED automatically goes off and the memory is cleared when the circuit breaker is reset.
