Type AC - B Curve
Type AC - B Curve
This enables both overcurrent protection and earth fault current protection by a single unit.
Single module Sentry RCBOs may be installed anywhere along the length of the busbar and will occupy one outgoing way.
They are suitable also for installation in Sentry Consumer Units and in Sentry two or four module enclosures.
The current carrying capacity of the cable should always exceed the current rating of the MCB.

MK Sentry Compact RCBOs
Type A - B Curve
Type A - B Curve
MK Sentry miniature RCBO with Type A RCD
The MK Sentry range features neutral switched type double pole RCBOs in one module format. The single module RCBOs are a combination of a Type B/C MCB and a Residual Current Device. This enables both overcurrent protection and earth fault current protection to be provided by a single unit.
This combination allows earth fault protection to be restricted to a single circuit, thus ensuring that only the circuit with the fault is interrupted (when groups of circuits are protected by an RCD, all circuits would be interrupted under fault conditions,
which may cause unnecessary inconvenience).
The operating switch on all MK Sentry RCBOs may be locked in either the ON or OFF position
without affecting the ability of the trip mechanism to operate.
MK Sentry RCBOs feature tunnel terminals of generous capacity, with 25mm² for live supply terminals and 10mm² for live
and neutral load terminals. The neutral supply (blue) is provided via flying lead.

AFDD/RCBO - DP B Curve 30mA Type A 6kA
Arc Fault Detection Device combined with RCBO (AFDD).
MK SENTRY AFDDs provide protection against fires caused by electrical arcing resulting from faulty wiring or poor connections.
The AFDD analyses curent/voltage characteristics to identify arcing and automically trip to isolate the circuit.
AFDDs detect arcing faults which can be undetected by MCBs and RCDs.
Types of arc fault:
Series arc fault, in-line conductor caused by;
- Loose connections
- Damaged cables (broken, crushed, worn)
- Rodent damage
Parallel arc fault, between live conductors, L-N and L-E undected by MCB/RCD resulting from;
- Damaged insulation
- Pierced insulation (power tools, nails etc)
- Rodent damage
- Poor wiring/damaged appliance plugs
Product Standard: BS EN62606, BS EN61009-1.
