EKL6-100B 10kA Electromagnetic type B RCCB with DC 6mA Protection

Product Description

EKL6-100B Type B RCD has novel appearance design, compact structure, good reliability, and high safety. They ensure higher protection levels with maximum operational continuity under all working conditions.Type B RCDs are suitable for non-linear circuits that can generate leakages with high direct current (> 6 mA) and/or high frequency components;Type B RCDs can ensure maximum safety in many applications,such as EV Charging Station,Crane and Elevator,PV and Wind power plants,etc.

Alternative Current Sensitive Pulsating direct current sensitive Surge current proof

B class

Tripping is ensured for sinusoidal AC
Residual currents pulsed DC residual currents,
alternating residual sinusoidal currents up to 1000Hz,
pulsating direct residual currents
and for smooth direct residual currents,
whether applied suddenly or increasing slowly.

They react to AC and pulsating DC 
fault current which reach 0 or almost 
0 within one time period of the 
mains frequency.
