⚡ Key Features

Protects circuits at 63 A with 10 kA short-circuit breaking capacity — rated for light industrial and commercial distribution boards.
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, KEMA tested — meets Indian regulatory requirements for use in government, commercial, and industrial electrical installations.
Genuine authorised ABB 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 1SYS273012R0631 protect at its rated 63 A?

A: The 1SYS273012R0631 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 1SYS273012R0631 mean in practice?

A: Breaking capacity (10 kA) is the maximum prospective short-circuit current the 1SYS273012R0631 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: Why is Curve D specified for the 1SYS273012R0631 and what loads is it optimised for?

A: Curve D on the 1SYS273012R0631 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: Can the 1SYS273012R0631 be DIN rail mounted in any standard distribution board?

A: Yes. This ABB 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 1SYS273012R0631 trips — how do I identify and reset it?

A: When the 1SYS273012R0631 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.
