Anti Vibration Electronic Shunt Trip MCCB

Introduction

HKM1E series electronic plastic case circuit breaker (hereinafter referred to as circuit breaker), suitable for AC 50Hz (60Hz), its rated insulation voltage is 800V,
The circuit with rated working voltage of 400V and rated working current up to 800A is used for infrequent conversion and infrequent motor starting. Circuit breaker has overload
Long delay inverse time limit, short circuit short delay inverse time limit, short circuit short delay time limit, short circuit instantaneous and undervoltage protection functions and residual current protection (optional), missing
Phase protection function (optional), which can protect the circuit and power equipment from damage. The protection features of the circuit breaker are complete and accurate, which can improve the reliability of power supply and avoid
Necessary power outage, in which the'Z, B'type control has a communication interface, can be "four remote" to meet the requirements of the control center and automation system.
Circuit breakers are divided into M type (higher breaking type) and H type (high breaking type) according to their rated limit short-circuit breaking capacity. The circuit breaker has a small size,
High breaking capacity, short arcing, anti-vibration and other characteristics.
◎The circuit breaker can be installed vertically (that is, installed vertically) or horizontally (that is, installed horizontally).
◎The circuit breaker has isolation function, and its corresponding symbol: "_x.
◎The circuit breaker cannot be reversed into the line, even if 1, 3, 5 are allowed to connect to the power line 2, 4, 6 to the load line.

Feature

O The circuit breaker has the characteristics of small size, high breaking, short arcing, anti-vibration and so on.
0 The circuit breaker can be installed vertically (that is, installed vertically) or horizontally (that is, installed horizontally).
O The circuit breaker cannot be reversed into the line, that is, only 1, 3, 5 can be connected to the power line, and 2, 4, 6 can be connected to the load line.

Normal working conditions and installation conditions

◎Altitude: ≤2000m.
◎Ambient temperature: -5C~ +409C.
◎Can withstand the influence of humid air.
◎Can withstand the influence of salt spray and oil spray.
◎The installation category of the main circuit of the circuit breaker is I, and the installation category of the remaining auxiliary circuits and control circuits is II.
◎When the maximum temperature is +409C, the relative humidity of the air does not exceed 50%, and it can operate at a lower relative humidity with a higher relative humidity,
Special measures should be taken for condensation that is occasionally generated due to temperature changes.
◎The maximum inclination is 22.5%.
◎In a medium without explosion hazard, and the medium does not have enough gas and conductive dust to corrode metal and destroy insulation.
◎ In a place free from rain and snow.
