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?

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.

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.
