REVOLUTIONARY!
The Memshield 2 RCBO combines the functions of an RCCB and an
MCB. The unique, revolutionary design allows hundreds of RCBO
possibilities within a module as little as 18mm wide. This allows a far
greater number of devices to be fitted into a distribution board.
All the features of the standard MCB are maintained but with the
added flexibility of residual current protection.
Memshield 2 SP RCBOs are suitable for use in any Memshield 2
distribution board.
Due to the unique method of construction any Memshield 2 SP orSPSN MCB can be fitted with residual current protection.
So for applications where a SP 63A type D MCB with 300mA time
delayed residual current protection is required MEM have the answer!
A new version of the residual current pod is available for use on 110V
50/60Hz systems.
ADDING EARTH FAULT PROTECTION TO YOUR MCB
There are three options each complying with BSEN61009:
1 Choose from the standard ready assembled range of RCBOs
incorporating Type C MCBs.
2 RCBOs factory assembled to order; select your MCB followed by the
earth fault sensitivity suffix from the relevant table. Remember any
SP or SPSN MCB can be fitted with earth fault protection.
Example: MDL150R100 = 50A SP Type D MCB factory
assembled with 100mA residual current protection.
3 Field fittable Residual Current (RC) Units; an RCBO can be
assembled on site. This provides two benefits: Previously installed
Memshield 2 SP & SPSN MCBs can be upgraded to include residual
current protection, also stock of SP & SPSN Memshield 2 MCBs
previously supplied can be upgraded to include earth fault protection.
Example: A field fitted MR30 will convert any SP or SPSN MCB
into an RCBO with 30mA residual current sensitivity.
NOTE: SPSN RCBOs must NOT be fitted in TPN type B distribution
boards. SPSN RCBOs are limited for use in DP versions of type A and
type B distribution boards.
To guarantee discrimination with downstream residual current devices
any upstream residual current device should be time delayed. The time
delay period is between 150-400mS.

The wide range of Memshield 2 devices are complemented by a
range of dolly padlocking devices.
For MCBs, RCCBs, RCBOs, and MCCBs the device mechanism is
trip free which allows it to be padlocked ‘ON’ for security, but in
the event of a fault condition the device will still operate to
disconnect the fault. The device dolly will move to the tripped
position when the dolly lock is removed. These devices can also be
padlocked in the ‘OFF’ position.
NOTE: Distribution board doors can be closed when an MCB is

types. Quartz stabilised devices have a running reserve time of
150Hr and a recharge time of 70Hr. Digital time switches have a
running reserve of 150Hr, and a full recharge time of 140Hr. All
time switches have 1 c/o contact per channel and are suitable for
switching 16A resistive, 2.5A inductive loads at 240v 50Hz. For
higher rated loads time switches should be used in conjunction
with MEM Autoline heating & lighting contactors.
