. INTRODUCTION
ln this range of Single Module Width RCBO's, each
product provides dual protection; from Over-current via
its MCB section, and from Earth Leaking Fault Current
(Residual Current) via its RCD section.
These devices provide RCD protection in full
compliance with the requirements of the Standard
BS EN 61009-1. They also provide very effective RCD
protection in the Supply Voltage Range of 110V to
253V a.c., meeting the requirements of the Standard
for sensitivity and trip speed at n and
IΔ
They meet the requirement of the current edition of the
UK Wiring Regulations (BS 7671), as regards ability to
trip with Earth Loop Impedance of up to 1667 Ω (for a
30m RCD), by being able to operate with Earth Loop
Impedance of up to 10,000 Ω.
