The C25V35E160 is a Schneider Electric ComPacT NSX 160 A molded-case circuit breaker in a 3-pole (3P) configuration, fitted with a MicroLogic 5.2 E electronic trip unit. This is the distribution-grade variant with integrated energy metering and communication capabilities — the trip unit itself handles overload (L), short-time short-circuit (S), and instantaneous short-circuit (I) protection profiles. Rated 160 A at 40 °C, it carries an 85 kA Icu breaking capacity at 500 V AC per IEC 60947-2, which means it can safely interrupt fault currents up to that level without upstream cascading.
The HB1 breaking capacity code maps to 75 kA Icu at 690 V AC, but the full rating table shows 85 kA at 500 V AC, 80 kA at 525 V AC, and 75 kA at 660/690 V AC. For a 480 V distribution panel, the 85 kA figure gives generous SCCR headroom — enough to coordinate with most downstream panelboard breakers without a current-limiting upstream device. The utilisation category is A, meaning it is not intended for frequent switching of motor loads under load; this is a distribution breaker, not a motor-circuit protector.
The 105 mm width and 161 mm height fit standard ComPacT NSX panel cutouts. IP40 front face (finger-safe) and IK07 impact rating cover most industrial panel environments.
