❓ Frequently Asked Questions

Q: What load can the 811297 protect at its rated 20 A?

A: The 811297 is rated to carry and protect circuits up to 20 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 20 A rating is used directly. Derate by 20% for ambient temperatures above 40°C.

Q: Is the 811297 suitable for both single-phase and three-phase systems?

A: The 811297 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 811297 be DIN rail mounted in any standard distribution board?

A: Yes. This Indoasian 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 811297 trips — how do I identify and reset it?

A: When the 811297 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.
