◼The NLDM1E series electronic moulded case circuit breakers (hereinafter referred to as circuit breakers) are suitable for AC 50Hz (or 60Hz) circuits with rated insulation voltage of 1000V, rated operating voltage of 400V and below, and rated operating current of 800A for infrequent switching and infrequent starting of motors. The circuit breaker has overload long delay inverse time, short circuit short delay inverse time, short circuit short delay definite time, short circuit instantaneous and undervoltage protection functions, as well as residual current protection (optional) and phase loss protection function (optional), which can protect the circuit and power equipment from damage. The circuit breaker has complete and accurate protection characteristics, which can improve power supply reliability and avoid unnecessary power outages. The "Z, B" type controller has a communication interface and can be used for "three remote" to meet the requirements of the control center and automation system.

◼Circuit breakers are classified into two types based on their rated ultimate short-circuit breaking capacity: M-type (medium breaking type) and H-type (high breaking type). This circuit breaker has the characteristics of small volume, high breaking capacity, short arc and high vibration resistance.

◼The circuit breaker can be installed vertically (i.e. upright) or horizontally (i.e. transversely).

◼This circuit breaker allows for reverse wiring.
