❓ Frequently Asked Questions

Q: What load can the 811228 protect at its rated 2.5 A?

A: The 811228 is rated to carry and protect circuits up to 2.5 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 2.5 A rating is used directly. Derate by 20% for ambient temperatures above 40°C.

Q: Can the 811228 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 811228 trips — how do I identify and reset it?

A: When the 811228 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 811228 suitable for both single-phase and three-phase systems?

A: The 811228 with 4 Poles can protect three-phase circuits. Each pole simultaneously interrupts one phase — ensuring all phases are de-energised on a fault.
