Product Description

Overview:
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, In≤30mA)
• Fire Protection (for locations exposed to fire hazard, In≤300mA)

4.Which are vulnerable to smooth DC residual currents?
• Photovoltaic systems, AC side.
• Charging stations for electric vehicles.
• Variable speed machine tools.
• UPS, computer data centers.
• Elevator controls.
• Cranes of all kinds.
• Electronic equipment on construction sites.
• Test set-ups in laboratories.
• General installations where DC smooth direct residual currents can be expected.

L80E 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 scenario.
