The C25F6TM160C is a 4-pole ComPacT NSX circuit breaker with a TM-D thermal-magnetic trip unit rated 160 A at 50 °C. The 36 kA Icu at 415 V AC (breaking capacity code F) means it can safely interrupt a fault current up to 36 kA at common 400 V-class distribution voltages — enough for most industrial switchboards where the available fault current stays under that ceiling. At 220/240 V the same breaker handles 85 kA, so it works across both low-voltage and higher-fault service entrances without a frame size change. The trip unit gives thermal protection for overloads (L) and magnetic protection for short circuits (I), with no earth-leakage module built in.
Front connections top and bottom, 35 mm connection pitch, 140 mm wide by 161 mm tall by 86 mm deep. IP40 enclosure means it's splash-resistant but not sealed against hose-down; keep it inside a cabinet rated for the environment.
