⚡ Key Features

100 mA sensitivity — intermediate sensitivity — used for fire protection and equipment earth-fault monitoring where a 30mA device would nuisance-trip.
25 A rated load current — the RCCB carries this full circuit current continuously while monitoring the live-neutral balance for any earth leakage.
4 Poles — for three-phase four-wire (TN-S/TT) installations; all four conductors pass through the toroidal CT for complete leakage detection.
Earth-leakage protection only — no overload or short-circuit protection; install in series with an appropriately rated MCB for full circuit protection.
Mandatory test button — simulate a leakage fault to verify the trip mechanism without live fault conditions; test monthly per IS 12640 recommendation.
Type AC — designed for purely sinusoidal AC residual currents on standard residential and commercial circuits.
Manufactured to IEC 61008 / IS 12640-1 — complies with the applicable Indian BIS and IEC international standards for this product category.
BIS certified (ISI mark) — meets Indian regulatory requirements for use in government, commercial, and industrial electrical installations.
Genuine authorised Indoasian product — sourced directly from the official distribution network with full manufacturer traceability and warranty.
GST invoice provided for India orders — valid for corporate procurement, government project orders, and public tender supply via myelectric.in.

❓ Frequently Asked Questions

Q: What is the significance of the 25 A rating on the 811724?

A: The 25 A rating is the device’s maximum continuous current carrying capacity under specified conditions (typically 40°C ambient). For circuit design, use 80% of this value as the design current to allow for derating due to grouping, temperature, and future load growth.

Q: Why is the 100 mA sensitivity specified on the 811724 and when should you choose a different rating?

A: 100 mA is the residual current at which the 811724 will trip within 300ms. A 30mA sensitivity provides additional shock protection (mandatory for socket circuits per IS 732). 100mA is used for fire protection (no shock protection). 300mA protects feeders without nuisance tripping. Choose based on the circuit’s risk profile — never use >30mA for socket outlet circuits in wet or high-risk locations.

Q: How many downstream circuits can be protected under the 811724 without nuisance tripping?

A: Downstream MCBs or RCBOs can be connected below the 811724, but the total standing leakage current of all connected circuits must not exceed 30–50% of the RCCB’s rated sensitivity — typically 9–15mA for a 30mA device. Each appliance with a filter (computers, VFDs, LED drivers) contributes 0.5–3mA of standing leakage, so limit the count of such loads per RCCB to prevent cumulative leakage causing nuisance tripping.

Q: Will the 811724 trip on earth faults from variable frequency drives (VFDs)?

A: VFDs, LED drivers, and switched-mode power supplies generate high-frequency leakage currents that can cause nuisance tripping in standard Type AC RCCBs. If your installation includes VFDs, use a Type A (for pulsating DC components) or Type F/B RCCB. The 811724 specification (AC or A type) determines suitability — check the product marking.

Q: What is the difference between an RCCB and a standard MCB — and why use the 811724?

A: A standard MCB protects against overload and short-circuit only. An RCCB adds earth leakage (residual current) detection — it trips on faults as low as 30mA to ground, protecting against electric shock and fire from insulation faults, which a standard MCB cannot detect. Choose the 811724 when the application specifically requires rccb characteristics.
