Product details

Overview

The LV438274 is a Schneider ComPact NSX630S DC molded case circuit breaker rated for 600 A switching current with a thermal-magnetic TM-DC trip unit, built for 4-pole DC distribution on a 750 V DC insulated system. It delivers a 100 kA breaking capacity at 500 V DC (S-class) and carries EN/IEC 60947 certification, with pollution degree 3 and IK07 impact rating for industrial panel environments.

Compared to the 3-pole LV438278 (NSX500 DC, 500 A), the LV438274 adds a fourth pole and a higher 600 A trip rating — pick the LV438278 when the BOM calls for 3-pole or 500 A; stay with the LV438274 for 4-pole 600 A designs.
