Intelligent Universal 690V Moulded Case Circuit Breaker

Intelligent Universal 690V Moulded Case Circuit Breaker

Introduction

HKW2-1600 intelligent universal circuit breaker (hereinafter referred to as circuit breaker), suitable for AC 50Hz, rated working voltage
To 690V, rated current 200 ~ 1600A distribution network, used to distribute electrical energy and protect the circuit and power equipment from overload,
The hazards of short circuit, under voltage, single-phase grounding (leakage) and other faults. The circuit breaker has intelligent protection function, selective protection is accurate,
Can improve power supply reliability and avoid unnecessary power outages. At the same time with an open communication interface, easy to connect with the field bus, can
Realize the "four remote" functions to meet the requirements of control centers and automation systems. Configure corresponding leakage transformer and intelligent controller
You can achieve leakage protection.
The circuit breaker has an isolation function and is represented by the symbol "_".
Circuit breakers with a rated operating current of 630A and can also be used as electric power in AC 50(60)Hz, 400V distribution networks
The machine is protected against overload, short circuit, phase loss, under voltage and ground faults. Under normal conditions, the circuit breaker can also be used as a line
Infrequent conversion and infrequent start of the motor.
The circuit breaker complies with GB 14048.2- -2012 "Low-voltage switchgear and control equipment Part 1: General rules"; and GB 14048.2
-2008 "Low-voltage switchgear and control equipment Part 2: Circuit breakers"; GB14048.2- 2010 "Low-voltage switchgear
And control equipment Part 4-1: contactors and motor starters electromechanical contactors and motor starters" and other standards.
