Overview

The Littelfuse 3PH39P18MM is a UL 508 Listed 3-phase busbar system designed for efficient and safe power distribution within industrial electrical panels. This 39-pole busbar features a 18 mm² copper conductor, providing a robust solution for power distribution. It is rated for 600V AC/DC and offers a 160A center-fed current capacity. Designed for easy installation, it mounts directly onto a 35mm DIN rail, significantly reducing the need for extensive wiring terminations and thereby lowering installation time and labor costs. The 3PH39P18MM is compatible with Littelfuse POWR-safe fuse holders from the LFPSM, LFPSC, LPSM, LPSC, and LPHV series, facilitating touch-safe fuse replacement. It boasts a Short Circuit Current Rating (SCCR) of 10kA when unprotected, and an impressive 100kA when protected by Class J fuses up to 175A. This busbar is an ideal component for control panels, motor control centers, and renewable energy systems requiring reliable and compact power distribution. The conductor material is copper, and the pitch between poles is 17.8 mm. It is RoHS Compliant and Lead (Pb) free.
