❓ Frequently Asked Questions

Q: What load can the LK30100K protect at its rated 10 A?

A: The LK30100K is rated to carry and protect circuits up to 10 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 10 A rating is used directly. Derate by 20% for ambient temperatures above 40°C.

Q: What happens when the LK30100K trips — how do I identify and reset it?

A: When the LK30100K 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 LK30100K suitable for both single-phase and three-phase systems?

A: The LK30100K with 3 Poles can protect three-phase circuits. Each pole simultaneously interrupts one phase — ensuring all phases are de-energised on a fault.

Q: Can the LK30100K be DIN rail mounted in any standard distribution board?

A: Yes. This LK30100K 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.
