      ⚡ Key Features

      • Protects circuits at 63 A with 10 kA short-circuit breaking capacity — rated for light industrial and commercial distribution boards.
      • 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.
      • 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 A9N4P63B protect at its rated 63 A?

      A: The A9N4P63B 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: What does the 10 kA breaking capacity on the A9N4P63B mean in practice?

      A: Breaking capacity (10 kA) is the maximum prospective short-circuit current the A9N4P63B can safely interrupt without damage. Before installing, verify that the prospective fault level at the installation point does not exceed 10 kA — this is checked using a fault level calculation or from the upstream transformer impedance data. Installing a breaker with insufficient breaking capacity is a serious safety violation.

      Q: Can the A9N4P63B 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 A9N4P63B trips — how do I identify and reset it?

      A: When the A9N4P63B 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: Is the A9N4P63B suitable for both single-phase and three-phase systems?

      A: The A9N4P63B with 4 Poles can protect three-phase circuits. Each pole simultaneously interrupts one phase — ensuring all phases are de-energised on a fault.
