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.
