❓ Frequently Asked Questions
Q: What is the significance of the 06–95 A rating on the 3MT7900-0PN20?
A: The 06–95 A rating is the device’s maximum continuous current carrying capacity under specified conditions (typically 40°C ambient). For circuit design, use 80% of this value as the design current to allow for derating due to grouping, temperature, and future load growth.
Q: What does the 1 NO + 1 NC contact configuration on the 3MT7900-0PN20 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.
