方便地安裝在任何設(shè)備上,采用螺釘固定或夾緊安裝在導(dǎo)軌上。

When the motor circuit breakers operate on their own can be manually controlled (controlled by the button or knob control), the connection may then access the remote control device;

Integrated thermal motor protection by the following - electromagnetic devices to provide circuit breaker;

All live parts are protective, not from the front panel directly from the finger touch;

With undervoltage release module, so you can switch off voltage conditions;

With SHT module, disconnect the device can use the remote control;

Open and closed motor circuit breakers installed in the control device can be used three padlocks locked in "N / C" position.

Superiority

ComPACt and concise, TeSys GV2 motor circuit breaker is only 45mm wide, and according to type of control, breaking capacity, motor protection devices and accessories, performance and functions of different categories.

Applications

Motor control and protection performance in line with IEC 947-2 and IEC 947-4-1 standards;

Easily installed on any device, fixed or clamped by screws installed in the rail.

1、按電動機(jī)的額定電流來確定斷路器的長延時動作電流整定值。

2、斷路器的6倍長延時動作電流整定值的可返回時間要長于電動機(jī)的實(shí)際起動時間。

3、斷路器的瞬時動作電流整定值:籠型電動機(jī)應(yīng)為8~15倍脫扣器額定電流;繞線型電動機(jī)應(yīng)為3~6倍脫扣器額定電流。

當(dāng)然,對于需要頻繁起動的電動機(jī),如果斷相運(yùn)行機(jī)率不高或者有斷相保護(hù)裝置,采用熔斷器與磁力起動器結(jié)合的方式來控制和保護(hù),也是比較合適的,因為這種保護(hù)方式便于遠(yuǎn)距離控制。
