HH12D fuse switch (HH12D-600 / 3 switch HH12D-600/3Z fuse fuse fuse switch HH12D-500/3Z switch HH12D-500 / 3 fuse fuse switch HH12D-400/3Z Switch HH12D-400 / 3 switch HH12D-300/3Z fuse fuse switch HH12D-300 / 3 switch HH12D-200/3Z fuse fuse switch HH12D-200 / 3 fuse switch HH12D-100 / 3Z fuse switch HH12D-100 / 3 switch HH12D-60/3Z fuse fuse switch HH12D-60 / 3 negative fuse switch HH12D-315 / 3 negative negative fuse fuse switch HH12D-315/3Z control switch HH12D-600 / 4 fuse switch HH12D-500 / 4 fuse switch HH12D-400 / 4 fuse switch HH12D-300 / 4 fuse switch HH12D-200 / 4 fuse switch HH12D- 100 / 4 fuse switch HH12D-60 / 4 negative fuse switch 
 ) 
 1. HH12D series fuse switch for AC 50 ~ 60Hz, rated insulation voltage up to 500V, rated working voltage of 415V (including 380V) has, uninterrupted current to 400 amp circuit, as the manual does not frequently connected with breaking load circuits and circuit overload and short circuit protection purposes. As with the neutral terminal, fuse switches can be used as general lighting circuit control switch for use. 
 High short-circuit current distribution circuit and motor circuit as a power isolating switch, load switch and emergency switch off the power supply lead to the use and protection. 


 2. HH12D fuse switches for the following operating conditions: 
 1) is not higher than 2000 m above sea level 
 2) The ambient temperature is not higher than +40 ° C not lower than -5 ° C 
 3) the air relative humidity less than 90% (+25 ℃) 
 4) Vertical installation with no strong vibration and shock of the occasion 
 5) in the absence of explosive gases and corrosive gas applications 

 2. HH12D classification and type 
 1) The thermal current four divided 100,200,315,400 ampere rating 
 2) divided by structure type two kinds of open and closed 
 3) divided by the number of pole 3-pole and 3 pole terminal with a neutral non-neutral terminal, 4-pole three kinds of 

 3. HH12D structure 
 Fuse switch mainly by the contact arc system, fuses, operating mechanism and the shell of four parts. Interrupter arc-resistant plastic to suppress, institutional simple, easy removal. Double-break contact system uses direct-acting type of long-shaped contact, moving contact is closed with filler tube fuse for the bridge arm of the U-shaped double-break contacts, long-form electric contacts have a higher stability of sex, double-break with a high breaking capacity. Closed tube fuses with filler ultimate breaking capacity of 50 kA, to meet the requirements of the general power grid. Pull a single lever operating mechanism structure and spring energy principle. Perform with the same spring making and breaking of the switch function, to ensure reliable switch making and breaking, and a clear sign-off. Pull-type operating handle, breaking the switch on or after the switch can be pushed into the enclosure, beautiful shape, the shell is equipped with interlock switch cover, ensure the lid is opened and the switch can not be connected after the switch is connected to the lid can not be opened.
