Protect people against indirect contacts and additional protection
against direct contacts.
Protect installations against fire hazard due to insulation faults.
Residual current circuit breakers are used in housing, tertiary
sector and industry.
1.2 Selection
Detectable wave form
| RCD Type | Suitable for electrical networks with |
|---|
| Pulsated DC current | Harmonics | Switching surges |
| AC CLASS | No | No | No |
| A CLASS | Yes | No | No |
| S, ASi CLASS | Yes | Yes | Yes |
A Class RCD may not work satisfactorily in electrical network
distributed by harmonics & switching transients and may give
nuisance triping.
AC class
Tripping is ensured for slowly increasing sinusoidal AC residual
currents
A class
Tripping is ensured for sinusoidal AC residual currents and for
pulsed DC residual currents, whether applied suddenly or increasing
slowly.
ASi Type - Full type A features + Si: Super immused (High immunity to
unwanted tripping)
Tripping is ensured not only for sinusoidal AC residual currents
but also for pulsed DC residual currents whether applied suddenly
or increasing slowly. S, G/SI type with filters against spurious
tripping caused by harmonics and transient surges. With the impact
of 8/20us surge 3000A, this high immunity RCCB will still be in
stable status.
Note: Our ASi type includes G/KV function and Si function.
1.3 Approvals and certificates
We certify that the RCCB has been tested for the following routine
tests as per IS: 12640 (Part 1):2016 and found to be complying
with the requirements.
1. Verification of the operating characteristic as per Seq. - D0
CL9.9
2. Verification of the operation of the test device at the limits
of rated voltage as per Seq. - D1 CL9.16
3. High Voltage Test as per D.3 of Annex D
4. Test for standard values of break time and non- actuating time
as per CL 5.3.12 (table -1)
Tripping sensitivity
10mA - precision instrument leakage protection and bathroom use.
30mA - additional protection against direct contact.
100mA - co-ordinated with the earth system according to the formula
I△n < 50/R, to provide protection against indirect contacts;
300mA/500mA - protection against indirect contacts, as well as fire
hazard.
Tripping time
Instantaneous
It ensures instantaneous tripping(without time-delay).
Short time delay ASi
(High Immunity/ Avoid nuisance tripping &blinding)
It ensures any tripping at least 10ms.
Selective 
It ensures total discrimination with a non selective RCD placed
downstream.

Product Description:
Residual Current Device
Residual Current Device (RCD), also known as a ground fault circuit
interrupter (GFCI) or a Residual Current Protection Device (RCPD),
is an electrical safety device that helps protect people from
electric shock and fire by automatically disconnecting the power
supply in the event of an electrical fault. RCDs are used to
protect against electrical shock and fire and are commonly found in
residential, commercial and industrial applications. RCDs are
available in a variety of types, including Residual Current Device
Type AC (Type AC), Residual Current Device Type A (Type A) and
Residual Current Device Type ASi (Type ASi). All of these types of
RCDs are designed to provide reliable protection in applications
where the risk of electric shock or fire is high. RCDs are designed
to detect and interrupt any leakage current that could cause an
electrical hazard. They are rated for a specific voltage (230V AC)
and frequency (50/60Hz) and must meet certain requirements for
impact endurance voltage (2kV). RCDs are an important part of any
electrical safety system and are essential for providing protection
against electric shock and fire.
