⚡ Key Features
- 1 A rated current — provides overload and short-circuit protection for the connected circuit.
- Curve C tripping characteristic — optimised for general-purpose and inductive loads (motors, mixed circuits) — trips magnetically at 5–10× rated current.
- 2 Poles — protects a single-phase circuit, switching both live and 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 A9N61521 protect at its rated 1 A?
A: The A9N61521 is rated to carry and protect circuits up to 1 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 1 A rating is used directly. Derate by 20% for ambient temperatures above 40°C.
Q: Why is Curve C specified for the A9N61521 and what loads is it optimised for?
A: Curve C on the A9N61521 trips magnetically at 5–10× rated current, making it ideal for general-purpose circuits including fluorescent lamps, small motors, and mixed loads. 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 A9N61521 suitable for both single-phase and three-phase systems?
A: The A9N61521 is a 2 poles device for single-phase circuits. For three-phase circuits, use a 3-pole or 4-pole MCB of the same series.
Q: Can the A9N61521 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 A9N61521 trips — how do I identify and reset it?
A: When the A9N61521 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.
