Measuring 4 inches wide by 6 inches high by 4 inches deep, it provides a compact, impact-resistant housing suitable for control wiring, terminal blocks, and small electrical assemblies. The flat screw cover secures with captive screws, reducing the risk of lost hardware during service. Multi-rating across NEMA 1, 2, 3, 3S, 3SX, 3X, 4, and 4X means a single enclosure meets a wide range of environmental exposure requirements. Licensed electricians and instrumentation technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThe NS644 is suited for both indoor and outdoor applications where moisture, dust, or corrosive wash-down conditions may be present. The NEMA 4X polycarbonate construction resists corrosion without the weight penalty of stainless steel, making it a practical choice for light industrial panels, outdoor disconnect housings, and junction boxes in wet locations. The included hinges and swing panels support organized internal layout and straightforward field wiring access.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePolycarbonate construction provides impact resistance and corrosion resistance without additional coating\u003c\/li\u003e\n  \u003cli\u003eNEMA 4X rating supports use in wet, wash-down, and mildly corrosive outdoor environments\u003c\/li\u003e\n  \u003cli\u003eMulti-NEMA rating: 1, 2, 3, 3S, 3SX, 3X, 4, and 4X covers a broad range of installation contexts\u003c\/li\u003e\n  \u003cli\u003eCaptive cover screws prevent hardware loss during repeated service access\u003c\/li\u003e\n  \u003cli\u003eIncludes hinges and swing panels for organized internal component layout\u003c\/li\u003e\n  \u003cli\u003ecULus Listed (E88685) and UL Listed 50 for code-compliance in NEC-governed installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style standard electrical enclosure suitable for residential, commercial, and light industrial electrical installations requiring NEMA 4X or lower environmental protection ratings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with applicable NEC requirements.
