The C103TM080C is a TM80D thermal-magnetic trip unit from the Schneider Electric ComPacT range, rated 80 A at 50 °C for 3-pole (3D) distribution applications. It provides LI protection — thermal overload (L) with adjustable long-time pickup Ir from 0.7 to 1 x In, and fixed magnetic short-circuit (I) pickup at 640 A.
Long-time protection delay tr is fixed at 120...400 s at 1.5 x In and 15 s at 6 x Ir. Instantaneous pickup Ii is fixed at 640 A.
It belongs to the ComPacT NSX100...250 range, meaning it fits NSX100, NSX160, and NSX250 circuit breaker frames.
It is designed and certified to EN/IEC 60947-2, the international standard for low-voltage circuit breakers.
