P-00 Modular DIN Rail Products MCB NB Miniature Circuit Breaker Color coded contact position indicator provides visual indication of the device status and insulation function Magnetic trip elements provide Type B, C and D trip characteristics while bimetallic element protect against slight overload Line and load side terminals accept bus bar connections for reduced costs and more efficient installation of multiple devices Trip-free mechanism, device operation can not be defeated by holding the operator in the ON position Heat dissipation gap provides better cooling Breaking capacity up to 000 7 Extendable DIN-rail holder for easy installation
MCB Modular DIN Rail Products P-00 NB Miniature Circuit Breaker. General. Function protection of circuits against short-circuit currents, protection of circuits against overload currents, switch, isolation, NB circuit-breakers are used in domestic installation, as well as in commercial and industry electrical distribution systems.. Selection Technical data of the network at the point considered: short-circuit current at the circuit-breaker installation point, which must always be less than the breaking capacity of this device, Network normal voltage. Tripping curves: B curve (-) protection for people and big length cables in TN and IT systems. C curve (-) protection for resistive and inductive loads with low inrush current. D curve(-) protection for circuits which supply loads with high inrush current at the circuit closing (LV/LV transformers, breakdown lamps).. pprovals and certificates Detailed information, please refer to Certificates Table on the last page.
