VKL11 Earth Leakage Circuit Breaker ELCB UL1053

VKL11 Earth Leakage Circuit Breaker(ELCB) UL1053

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 Si, G, KV
It ensures any tripping at least 10ms.
Si: Super immunised (High immunity to unwanted tripping).
Selective
It ensures total discrimination with a non selective ELCB(RCCB) placed downstream.
