RCCB-B-80A Residual Current Circuit Breaker

Scope of application

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

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.
