Electromagnetic Leakage Protector SR6HM RCCB 16-63A In 2P, 4 poles
Function:
♦ Control electric circuits
♦ Protect people against indirect contacts and additional protection against direct contacts
♦ Protect installations against fire hazard due to insulation faults
♦ Residual current circuit breakers are used in housing, tertiary sector and industry
♦ Support 35mm Din-rail installation
Selection:
♦ Detectable wave form
♦ AC type
RCCB which tripping is ensured for residual sinusoidal alternating currents, whether suddenly applied or slowly rising, Symbol 
♦ 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
