⚡ Key Features

300 mA sensitivity — coarse sensitivity for fire protection on large circuits — must be backed by a 30mA RCCB at the point of use for personnel protection.
2 Poles — for single-phase circuits; both live and neutral pass through the sensing core.
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 300 mA sensitivity specified on the GMR602P018 and when should you choose a different rating?

A: 300 mA is the residual current at which the GMR602P018 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: Will the GMR602P018 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 GMR602P018 specification (AC or A type) determines suitability — check the product marking.

Q: How many downstream circuits can be protected under the GMR602P018 without nuisance tripping?

A: Downstream MCBs or RCBOs can be connected below the GMR602P018, 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: What is the difference between an RCCB and a standard MCB — and why use the GMR602P018?

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 GMR602P018 when the application specifically requires rccb characteristics.
