⚡ Key Features

  • 630 A frame rating — handles the full rated current continuously; designed for feeder and sub-distribution protection where fault levels exceed MCB capability.
  • 75 kA breaking capacity at 415V AC — safely clears bolted three-phase faults in high-power substations and MV/LV transformer secondaries.
  • Thermal-magnetic trip unit — factory-calibrated overload and short-circuit protection; suitable for standard feeder circuits without electronic adjustment.
  • 4 Poles — three-phase + switched neutral (TN-S system) for full four-pole isolation per IEC 60364.
  • CompacT NSX form factor — 70mm wide per pole; designed for high-density LV switchboards with up to 3 units per standard 250mm busbar bay.
  • Rotary handle with padlocking points — LOTO compliant; handle locks in OFF position with up to 3 padlocks, preventing accidental energisation during maintenance.
  • Manufactured to IEC 60947-2 / IS 13947-2 — 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.

❓ Frequently Asked Questions

Q: What load can the C63V46E630 protect at its rated 630 A?

A: The C63V46E630 is rated to carry and protect circuits up to 630 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 630 A rating is used directly. Derate by 20% for ambient temperatures above 40°C.

Q: What does the 75 kA breaking capacity on the C63V46E630 mean in practice?

A: Breaking capacity (75 kA) is the maximum prospective short-circuit current the C63V46E630 can safely interrupt without damage. Before installing, verify that the prospective fault level at the installation point does not exceed 75 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 C63V46E630 be motorised for remote switching and automation?

A: Yes. Schneider Electric MCCBs in this series support rotary handle adaptation and motorised operating mechanisms as accessories, enabling remote ON/OFF switching via PLC, SCADA, or BMS. Motorised MCCBs are used for automatic load management and remote trip in automated distribution systems.

Q: What trip unit type does the C63V46E630 use — thermal-magnetic or electronic?

A: Refer to the product label or datasheet for the exact trip unit specification. The trip unit determines adjustability and protection accuracy.

Q: Is the C63V46E630 suitable for use as a motor branch circuit protector (Type E coordination)?

A: MCCBs used for motor branch circuit protection must be coordinated with the downstream overload relay for Type 2 coordination (no damage to contactor or relay on short-circuit). Verify the Schneider Electric coordination table for the specific contactor-overload-MCCB combination to confirm Type 1 or Type 2 coordination is achieved.
