⚡ Key Features
- 40 A rated current — provides overload and short-circuit protection for the connected circuit.
- 4 Poles — protects a three-phase four-wire circuit with switched neutral; fits standard 35mm DIN rail in distribution boards.
- Thermal-magnetic trip mechanism — bimetal element trips on sustained overload, instantaneous magnetic trip on short-circuit; two independent protection functions in one compact module.
- Visi-Trip indicator — handle snaps to a clearly visible mid-position on trip, allowing instant fault identification without opening the panel door.
- Compatible with Acti9 comb busbar (1P, 2P, 3P, 3P+N) — parallel wiring of multiple MCBs without individual cables, cutting panel wiring time significantly.
- Manufactured to IS 8828 / IEC 60898-1 (residential) and IEC 60947-2 (industrial) — complies with the applicable Indian BIS and IEC international standards for this product category.
- BIS certified, CE marked, RoHS compliant — meets Indian regulatory requirements for use in government, commercial, and industrial electrical installations.
- Genuine authorised Schneider Electric product — sourced directly from the official distribution network with full manufacturer traceability and warranty.

- 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 A9N4P40CIN protect at its rated 40 A?
A: The A9N4P40CIN is rated to carry and protect circuits up to 40 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 40 A rating is used directly. Derate by 20% for ambient temperatures above 40°C.
Q: Is the A9N4P40CIN suitable for both single-phase and three-phase systems?
A: The A9N4P40CIN with 4 Poles can protect three-phase circuits. Each pole simultaneously interrupts one phase — ensuring all phases are de-energised on a fault.
Q: Can the A9N4P40CIN be DIN rail mounted in any standard distribution board?
A: Yes. This Schneider Electric MCB uses the standard 35mm EN 60715 DIN rail and 17.5mm module width, making it compatible with all major brand distribution boards and enclosures. Terminal capacity accommodates both rigid and flexible conductors up to the rated cross-section.
Q: What happens when the A9N4P40CIN trips — how do I identify and reset it?
A: When the A9N4P40CIN trips on fault, the handle moves to a midway position (between ON and OFF), distinctly visible from a distance. To reset: (1) identify and rectify the fault, (2) push the handle fully to OFF, (3) then switch back to ON. Never force-reset without investigating the fault cause.
Q: Which Schneider Electric accessories are compatible with the A9N4P40CIN?
A: The Schneider Electric Acti9 series supports snap-on accessories including auxiliary contacts (OF), alarm contacts (SD), shunt trip coils (MX), undervoltage releases (MN), and comb busbars. Accessories are series-specific — always verify compatibility using the Schneider Electric product catalogue before ordering. myelectric.in can advise on the correct accessory part numbers for the A9N4P40CIN.
