MODULAR CIRCUIT BREAKERS (MCB) FOR OVER-CURRENT
PROTECTION VA47-100
ENG
Modular circuit breakers for overcurrent protection of VA47-100 series for
household and similar use of IEK trademark (hereinafter referred to as “circuit
breakers”) are intended for application in the single or three-phase AC electric
networks with rated line-to-line voltage limited to 400 V and 50 Hz frequency.
These circuit breakers meet the requirements of EN 60898-1.
Circuit breakers exercise a function of automated cutting off the electric
equipment at overcurrents (overload or short circuit) and day-to-day
management of electric network arms.
Main application: electrical distribution panels, accounting and distributing
boards of residential, public and industrial buildings as well as individual electric
power consumers.
Operation conditions:
– operation temperature range – from –40 to +50 °Ñ;
– base altitude – 2000 m max.;
– relative air humidity – 50 % at +40 °Ñ. Permitted operation of circuits
breakers at the relative air humidity: 90 % at +20 °Ñ;
– operative position: vertical with the possible deviation up to 90°.
Electric schematic diagrams are shown on Figure 6 of Appendix 1.
Overall dimensions are shown on Figure 5 of Appendix 1.
