Our MCB breaking capacity is up to 10-15KA , the DC
voltage for MCB MCCB SPD is up to 1500V.
It is electro-mechanical in nature.The highlinght here is that it can be wired in either direction.This makes retrofit a breeze with regards to matching wiring conventions.it also busbar campatible
In addition to fault currents in the AC and pulse current range,type B also detects DC fault currents,which can occur in frequency inverter controls,photovoltaic systems as well as through the electronic use in households,and increases safety considerably
● Applications with:
. Appliances and motors with 1Phase frequency converters with PFC([Power factor compensation)or .1 phase frequency converters supplied between phase/phase or .3 phase frequency converters
. DC systems(photovoltaic systems,ups units..)
. In front of PV Systems/ Battery banks/ UPS Units/EV charging Medical devices/ Frequency converters/ Motor controllers
. Sensitive to all residual currents according up to lkHz.
