⚡ Key Features

Protects circuits at 40 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 1SYS273012R0401 protect at its rated 40 A?

A: The 1SYS273012R0401 is rated to carry and protect circuits up to 40 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 40 A rating is used directly. Derate by 20% for ambient temperatures above 40°C.

Q: What does the 10 kA breaking capacity on the 1SYS273012R0401 mean in practice?

A: Breaking capacity (10 kA) is the maximum prospective short-circuit current the 1SYS273012R0401 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 1SYS273012R0401 and what loads is it optimised for?

A: Curve D on the 1SYS273012R0401 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: What happens when the 1SYS273012R0401 trips — how do I identify and reset it?

A: When the 1SYS273012R0401 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 1SYS273012R0401 suitable for both single-phase and three-phase systems?

A: The 1SYS273012R0401 with 3 Poles can protect three-phase circuits. Each pole simultaneously interrupts one phase — ensuring all phases are de-energised on a fault.
