Porduct Overview
Description
RCBOs type B grant protection to persons and machineries in presence of DC current and high frequency AC fault current. Among the several types of RCBOs, type B provides the utmost level of protection.
1. Residual current sensitivity – UNIVERSAL
- AC pure sinus residual current, 50/60Hz
- A sinus and pulsating direct current, 50/60Hz
- B: AC + A + smooth direct current + high frequency (1kHz)
2. Standards
- IEC/EN 61009-1 Basic standards for RCBOs AC and A type
- IEC/EN 62423 additional requirements for type B
3. Typical applications
- Fault protection (protection against indirect contact of live parts
- Additional protection (protection in case of direct contact of live parts, I?n≤30mA)
- Fire Protection (for locations exposed to fire hazard, I?n≤300mA)
4.Which are vulnerable to smooth DC residual currents?
EKL5-63 B type RCBO maximum current can reach 63 amps, and three leakage current options of 30mA, 100mA and 300mA are available to meet the needs of different scenarios.
