Leakage Protector PR8NM Residual Current Operated Circuit Breaker
2pole
Product Description:
16-100 A rated current 2 pole and 4 pole Leakage Protector are widely used in housing, tertiary sector and
industry, 35mm din-rail installation is supproted. It is mainly
used for controling electric circuits, it can be used for protecting people
from indirect or direct contacts. Keep you away from fire hazard
which caused by insulation faults during installation.

Selection:
♦ Detectable wave form
♦ AC type
♦ A type
RCCB for which tripping ensured for residual sinusoidal alternating
currents and residual pulsating direct currents, whether suddenly
applied or slowing rising, Symbol
Tripping sensitivity:
♦ 30 mA--additional protection against direct contact
♦ 100mA--co-ordinated with the earth system according to the
formula In＜50/R, to provide protection against indirect contacts
♦ 300mA, protection against indirect contacts, as well we fire
hazard
Tripping time:
♦ Instantaneous: It ensures instantaneous tripping (without time-delay)
♦ Short time delay 
: It ensures any tripping at least 10ms
♦ Selective 
: It ensures total discrimination with a nonselective RCD placed
downstream
