⚡ Key Features

100 mA sensitivity — intermediate sensitivity — used for fire protection and equipment earth-fault monitoring where a 30mA device would nuisance-trip.
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), RoHS compliant (LF versions) — meets Indian regulatory requirements for use in government, commercial, and industrial electrical installations.
Genuine authorised Polycab 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.
Worldwide export available — UAE, Singapore, UK, USA, Sri Lanka & more. Contact +91 94814 00316 for bulk pricing and international shipping.

❓ Frequently Asked Questions

Q: Why is the 100 mA sensitivity specified on the GMR604P012 and when should you choose a different rating?

A: 100 mA is the residual current at which the GMR604P012 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 GMR604P012 without nuisance tripping?

A: Downstream MCBs or RCBOs can be connected below the GMR604P012, 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 GMR604P012 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 GMR604P012 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 GMR604P012?

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 GMR604P012 when the application specifically requires rccb characteristics.
