Short circuit breaking capacity 10kA.

Large terminal capacity
RCBOs have 35mm² for cool running while in operation.


Protection in case of loss for supply neutral
Even in event of loss of supply neutral, Havells RCBO provides protection against earth faults. The Functional Earth (FE) white color wire connected to earth provides this protection.

Controlled response & immunity to nuisance tripping
The trip level and the response time of the Havells VD (Voltage Dependent) RCBO using electronic circuit is set to very precise values and thereby provide greater immunity to nuisance tripping that can be caused by mains borne noise, surge voltages, lighting surges, reactive loads, mains filters, etc.

Neutral to earth faults
A connection that occurs between N and E on the load side of any RCBO will impact on its performance and cause the trip level to increase. In the case of a N - E fault, the user may have no way of knowing that this fault exists and that the RCBO have been desensitized. Under this conditions, the Havells VD RCBO provides a for greater level of protection than a normal VI(Voltage Independent)RCBO.

Aesthetics & convenience
- The new module's unique compact construction enables for move devices to be fitted into a distribution board than    previously possible, and 2 Module RCBO can simple replace existing MCB 2 pole when upgrading a board
- High stacking density = smaller chassis & distribution boards.

Reliability & continuity of service
- Enhanced discrimination with Havells MCBs
- Backup to 10kB with BS & DIN fuses
- Retrofits Havells MCBs in distribution boards with no modifications in general
- Robust construction

Energy limiting
Havells RCBO meets the requirements for energy let through by IEC & British Standard for energy limiting class3.

Characteristics

Features a single pole switched neutral & three pole switched neutral RCBO.
Line voltage dependent tripping.
Dual termination facility provided on incoming side (bus bar as well as cable termination).
Single value of rated residual operating current.
Protection against electrocution (person comes in direct or indirect contact with live parts of electrical network).
Protection of installation against fire hazards. Protection against overload (cuts off supply when current flowing through     cable exceeds rated current of RCBO).
Protection against short circuit (when phase comes in direct contact either with phase conductor, neutral conductor or     earth).

Additional Range-Type A & S

Type A - Pulsating DC Protection
Any electrical appliance with power control has the ability to produce earth fault currents with pulsating DC (rectified AC) components. RCBOs that provide this type of protection are referred to as type A RCBOs.
Standard VI RCBOs do not provide this protection, and are referred to as type AC RCBOs. havells have been specifically designed to provide protection against pulsating DC fault currents.

Type S - Selective or Time Delay
- RCBOs are also divided into two categories determined by their response time to an earth fault current, as follows.
- General type - having a trip time<300mS for fault currents of IΔn and <40ms for fault currents>51Δn.
- S Type - having a trip time of 150-500mS for IΔn, and 40-130mS for >51Δn.

(I Δn is the rated residual operating current of the RCBO)

As the name implies, general types are intended for general purpose use. However, S (selective) types are normally used in conjunction with downstream general type RCBOs.
The S type effectively provides discrimination in terms of the response time to earth fault currents for upstream ad downstream RCBOs. For example, when two RCBOs are connected in series the first RCBO will often be an S type.
