AC RCCB&RCBO
JB1L-40A/AC RCCB with Overcurrent Protection
Product Features
Protection against risk of fire
Protection against risk of electric shock
Protection against overload
Protection against short circuit
Contact position indicator
Types
Both RCCBs and RCBOs are devided into types depending on the operating function:
Type AC 
：For which tripping is ensured for residual sinusoidal alternating currents, whether suddenly applied or slowly rising.
Type A 
：For which tripping is ensued for residual sinusoidal alternating currents and residual pulsating direct currents, whether suddenly applied or slowly rising.
