Overview

The ABB Circuit Safe Polycarbonate NEMA Enclosure (NL644B) is a durable, UL 50-listed polycarbonate enclosure designed for harsh industrial environments. This 6x4x4 inch enclosure provides superior protection for electrical components against impact, chemicals, UV exposure, and corrosion, with an external hinge for easy maintenance access. Constructed from high-impact polycarbonate resin, it exceeds traditional fiberglass enclosures in impact resistance by nearly three times, ensuring long-term reliability in outdoor and indoor applications. Meeting NEMA Types 4X, 12, and 13 standards, the NL644B is ideal for manufacturing plants, utility facilities, and MRO/OEM applications where equipment requires protection from water, dust, and corrosive agents. The enclosure ships with mounting feet, hinge caps, and screws, while back panels must be ordered separately. Optional factory-installed pad-lockable quick-release latches (part no. CJTL) are available. With a temperature range of -40°F to 185°F and UV rating of F1, this enclosure delivers stable performance in extreme conditions. Its lightweight yet sturdy design simplifies handling and installation, while brass screw inserts and 304 stainless steel screws ensure corrosion-resistant durability.
