⚡ Key Features

32 A current rating with combined overload + short-circuit + earth-leakage protection in one device — complete circuit protection without a separate MCB and RCCB.
30 mA individual earth-leakage protection — an earth fault on this circuit trips only this RCBO; other circuits in the board remain energised, unlike a shared RCCB which disconnects all.
4 Poles — designed for three-phase circuits requiring combined protection.
Single DIN rail module — same 17.5mm or 1P width as a standard MCB; maximises the number of protected circuits in a fixed enclosure size.
Manufactured to IEC 61009 / IS 12640-2 — complies with the applicable Indian BIS and IEC international standards for this product category.
BIS certified where applicable — meets Indian regulatory requirements for use in government, commercial, and industrial electrical installations.
Genuine authorised 32 A Havells | DHBMACTN8030032 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: What load can the DHBMACTN8030032 protect at its rated 32 A?

A: The DHBMACTN8030032 is rated to carry and protect circuits up to 32 A continuously. For motor loads, ensure the full-load current (FLC) of the motor does not exceed this rating. For resistive loads (heaters, lighting), the 32 A rating is used directly. Derate by 20% for ambient temperatures above 40°C.

Q: Why is the 30 mA sensitivity specified on the DHBMACTN8030032 and when should you choose a different rating?

A: 30 mA is the residual current at which the DHBMACTN8030032 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: What is the difference between an RCBO and a standard MCB — and why use the DHBMACTN8030032?

A: A standard MCB protects against overload and short-circuit only. An RCBO combines MCB overcurrent/short-circuit protection AND RCCB earth leakage detection in a single 1-module device — ideal where both forms of protection are needed in limited panel space. Choose the DHBMACTN8030032 when the application specifically requires rcbo characteristics.
