⚡ Key Features

63 A current rating with combined overload + short-circuit + earth-leakage protection in one device — complete circuit protection without a separate MCB and RCCB.
300 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.
2 Poles — designed for single-phase final circuits in consumer units and small distribution boards.
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 Leading Brand 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 4113 40 protect at its rated 63 A?

A: The 4113 40 is rated to carry and protect circuits up to 63 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 63 A rating is used directly. Derate by 20% for ambient temperatures above 40°C.

Q: Why is the 300 mA sensitivity specified on the 4113 40 and when should you choose a different rating?

A: 300 mA is the residual current at which the 4113 40 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 4113 40?

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 4113 40 when the application specifically requires rcbo characteristics.
