At 480 V AC the rating holds at 65 kA Icu (UL 60947-4-1), so it stays usable on 480 V services common in North American plants. The MicroLogic 2.2 provides L (long-time overload), So (short-time short-circuit with fixed delay), and I (instantaneous) protection curves. Mounts on a backplate in horizontal or vertical orientation (flat on the back). IP40 enclosure protection is fine for clean indoor panels; IK07 impact rating handles accidental tool drops during maintenance. ## Selectivity and coordination For applications requiring zone-selective interlocking or ST delay, a Category B breaker (MicroLogic 5/6 trip units) would be the correct choice. The 4-pole configuration (switched neutral on the left) suits 3-phase + N distribution where the neutral must be protected or switched.","metaTitle":"C16H42D160 ComPacT NSX160H 160A 4P MCCB, 70kA 415V","metaDescription":"C16H42D160 ComPacT NSX160H 160A 4P circuit breaker with MicroLogic 2.2 electronic trip unit. 70 kA Icu at 415 V AC.
