Anti-interference scheme excluding the faulty actuation: № RU Patent No. 124453.
|
Arc chute made of 13 steel plates in order to effectively quench the arc.
|
Arc removal plate of movable contact is made as a smooth curve, that greatly facilitates the pulling of the arc into the arc chute.
|
Expansion of RCBO34 (AVDT34) line for 40, 50, 63A currents with the setting of 30, 100, 300 mA.
|
Latch on a DIN-rail with double fixed position for ease of installation work.
|
Notches on the contact clamps reduce heat loss and increase the mechanical stability of the connection.
|
Soldering of the silver-containing composite increases the wear resistance of the contact group and reduces the contact resistance.
|
The compact design of the automatic circuit breaker controlled by residual current, with integrated overcurrent protection, holds 4 standard modules on the panel.
|
The indicator of status of the main circuit provides accurate information about the status of contacts regardless of handle position. The rated conditional short circuit current is 6000 A. The extended range of operating temperatures is from -25 °C to + 40 ° C.
|
The possibility of simultaneous connection of FORK bus and flexible conductor for the distribution of circuit power supply through the upper terminal clamps, as well as the possibility of connection via PIN bus.
|
The RCBO34 (AVDT34) design for the currents above 40A provides quick assembly / disassembly without the use of tools and a stable fit on DIN-rail.
|
Trip-free mechanism of the new design, which ensures a quick break of the main contacts.
