VFL001 Earth Leakage Circuit Breaker(ELCB) Type A Type AC Type ASi
1. General
1.1 Function
Control electric circuits.
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
| ELCB 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 ELCB 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 ELCB 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 ELCB(RCCB)
placed downstream.

Product Description:
ELCB Earth Leakage Circuit Breaker is a safety device used to
protect people and property from electric shock and fire caused by
earth leakage. It provides overcurrent protection, sensitive to
earth leakage current, and can quickly turn off the circuit within
0.1s to protect people and property from electric shock.
Our ELCB has below advantages:
a. we guarantee 5 years' warranty;
b. The material of RCCB shell is PA66 instead of bakelite (bakelite
shell is easily broken when drop onto ground)
c. Bottom lock material is PA66 instead of iron with spring (iron
lock with spring is easily broken and not nice looking)
d. Our quality control standard is very strict. We have perfect
test equipment in our factory to tests products during production,
all the ELCB will be tested and checked one by one at least 5 times
before delivery.
e. VORAX has been certified by the ISO9001 Quality Management
System, and all products produced in VORAX are kept in strict
accordance with international IEC/EN standards.
f. VORAX products have gained variety of international
certifications, including SAA, CB, CE, NF, SEMKO etc.
We are the only Chinese company who have ISI certificate for India.
We are the one of two companies who have NF certificate for France.
So if u buy our ELCB, the good quality of products is 100%
guaranteed and you won't get any trouble with certificate issues.
The price we quote is worth.
