❓ Frequently Asked Questions

Q: What happens when the 4087 02 trips — how do I identify and reset it?

A: When the 4087 02 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 4087 02 suitable for both single-phase and three-phase systems?

A: The 4087 02 with 4 Poles can protect three-phase circuits. Each pole simultaneously interrupts one phase — ensuring all phases are de-energised on a fault.

Q: Can the 4087 02 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.
