❓ Frequently Asked Questions

Q: What does the 1 NO + 1 NC contact configuration on the AUATAC240HR mean?

A: This device has both Normally Open (NO) and Normally Closed (NC) contacts. NO contacts close when the device operates (energised/tripped); NC contacts open. This allows both start-interlock and stop-interlock circuits from a single device.

Q: What happens when the AUATAC240HR trips — how do I identify and reset it?

A: When the AUATAC240HR 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 AUATAC240HR suitable for both single-phase and three-phase systems?

A: The AUATAC240HR with multiple poles can protect three-phase circuits. Each pole simultaneously interrupts one phase — ensuring all phases are de-energised on a fault.

Q: Can the AUATAC240HR be DIN rail mounted in any standard distribution board?

A: Yes. This AUATAC240HR 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.
