⚡ Key Features

25 A rated current — provides overload and short-circuit protection for the connected circuit.
Curve D tripping characteristic — optimised for high-inrush loads (transformers, solenoids, welding machines) — trips magnetically at 10–20× rated current.
3 Poles — protects a three-phase circuit without 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.
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.
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 A9N3P25D protect at its rated 25 A?

A: The A9N3P25D is rated to carry and protect circuits up to 25 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 25 A rating is used directly. Derate by 20% for ambient temperatures above 40°C.

Q: Why is Curve D specified for the A9N3P25D and what loads is it optimised for?

A: Curve D on the A9N3P25D trips magnetically at 10–20× rated current, making it ideal for highly inductive loads with large inrush — transformers, large motors, welding machines. Using the wrong curve can cause nuisance tripping (too sensitive) or inadequate protection (not sensitive enough). Always match the curve to the load’s inrush characteristics.

Q: Is the A9N3P25D suitable for both single-phase and three-phase systems?

A: The A9N3P25D with 3 Poles can protect three-phase circuits. Each pole simultaneously interrupts one phase — ensuring all phases are de-energised on a fault.

Q: Can the A9N3P25D 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 A9N3P25D trips — how do I identify and reset it?

A: When the A9N3P25D 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.
