What the 80 A TM-D trip unit and 200 kA Icu mean for your distribution panel
The C10R4TM080 is a Schneider Electric ComPacT NSX circuit breaker with a 4-pole frame, an 80 A thermal-magnetic TM-D trip unit, and an R-breaking-capacity rating of 200 kA Icu at 415 V AC. The TM-D trip unit combines a thermal bimetal for overload protection (L) and a magnetic coil for short-circuit protection (I), both adjustable within the trip unit's range. At 690 V AC the Icu is still 45 kA, covering most industrial line-to-line voltages.
