Product Specification

                                            4 Poles Mccb Low Voltage Moulded Circuit Breaker Switch​

Introduction

             HKW1-1000 intelligent universal circuit breaker (hereinafter referred to as circuit breaker), suitable for AC 50Hz, rated voltage 400V
(380V), in a distribution network with a rated current of 200~1000A, it is mainly used to distribute electrical energy and protect circuits and power equipment from
Damaged by overload, short circuit, under voltage, single-phase grounding and other faults. Under normal conditions, it can be used for infrequent conversion of lines,
The page can be used for infrequent starting and protection of the motor.
The circuit breaker has a variety of intelligent protection functions, selective protection is accurate, can improve the reliability of power supply, avoid unnecessary
9
Blackout. The circuit breaker has isolation function, the symbol is marked as
The technical performance of the circuit breaker conforms to GB14048.2 "Low-voltage switchgear and control equipment Part 2: Circuit breaker"
IEC60947-2 "Low-voltage switchgear and control equipment Part 2: Circuit breaker" and other standards.
