❓ Frequently Asked Questions

Q: Can the 4085 85 be DIN rail mounted in any standard distribution board?

A: Yes. This Legrand 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 4085 85 trips — how do I identify and reset it?

A: When the 4085 85 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 4085 85 suitable for both single-phase and three-phase systems?

A: The 4085 85 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.
