- Description
The C25H3TM250 is a 3-pole Schneider Electric ComPacT NSX250H moulded case circuit breaker rated 250 A, with a TM-D thermal-magnetic trip unit and 70 kA breaking capacity (Icu) at 380/415 V AC. Rated operational voltage (Ue) is 690 V AC. At 250 A it tops out the current rating of this 3-pole H-rated frame.

Selection Notes
At the top of the NSX250H 3-pole current range, the C25H3TM250 suits feeders needing the full 250 A with the 70 kA fault-current margin of the H frame. Against the 200 A sibling in the same body, the adjustable 5...10 x In instantaneous pickup on both units lets the magnetic trip be tuned to the circuit, while the thermal setting (0.7...1 x In) still allows some derating below each unit's frame current.
