❓ Frequently Asked Questions

Q: Is the DHMXCSNZ020 suitable for both single-phase and three-phase systems?

A: The DHMXCSNZ020 is a 1 pole device for single-phase circuits. For three-phase circuits, use a 3-pole or 4-pole MCB of the same series.

Q: Can the DHMXCSNZ020 be DIN rail mounted in any standard distribution board?

A: Yes. This Leading Brand 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 DHMXCSNZ020 trips — how do I identify and reset it?

A: When the DHMXCSNZ020 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.
