Overview
Product Overview
DLM1E series electronic MoldedCase Circuit Breakers (hereinafter referred to as circuit breakers) are suitable for infrequent switching and infrequent starting of motor in circuits with AC 50Hz (or 60Hz), rated insulation voltage of 800V, rated working voltage of 690V and below, and rated working current of 800A.
The circuit breaker has overload long delay anti-time limit, short-circuit short delay anti-time limit, short-circuit short delay fixed-time limit, short-circuit instantaneous and under-voltage protection function as well as residual current protection (optional), phase-loss
protection function (optional), which can protect the line and power supply equipment from being damaged.
The protection characteristics of the circuit breaker are complete and accurate, which can improve the reliability of power supply and avoid unnecessary power outages, B” type control with communication interface, can be “four remote” to meet the requirements of the control center and automation system.
The circuit breakers can not be inverted into the line, that is, only allows 1, 3, 5 connected to the power line, 2, 4, 6 connected to the load line.
The circuit breakers are divided into two types according to their rated ultimate short-circuit breaking capacity: L-type (standard type), M-type (higher breaking type) and H-type (high breaking type).
The Circuit Breaker is characterized by small size, high breaking capacity, short flying arc, anti-vibrationand so on.
The Circuit Breaker can be installed vertically (i.e. vertically mounted) or horizontally (i.e. horizontally mounted).
The Circuit Breaker conforms to: IEFC60947-2, GB14048.2 standard.
