FAQs
ABB 2CPX041778R9999 NH1 fuse switch disconnector is designed for CombiLine interior fitting modules and 3-pole low-voltage switchgear. It fits a 750 mm wide, 450 mm high enclosure with a built-in depth of 225 mm and 108 DIN place units. Mounting is plate-based (WR frame) and supports three mountable devices, enabling clean, field-adjustable layouts.
Key specifications for the 2CPX041778R9999 include a rated operational voltage of 400 V, maximum 400 V operation, 440 A rated current, 3 poles, and three fuse switch disconnectors housed in a 750 mm by 450 mm by 225 mm enclosure with 108 DIN places. This module is ideal for mid-range LV distribution in industrial control cabinets.
This module carries CE conformity and is designed to DIN EN 61439-2/3 compliant assemblies. RoHS information confirms restricted use of hazardous substances, with the RoHS date 2024-09-03 and REACH declarations indicating no substances above 0.1 mass percent. WEEE categorization notes the part is not in WEEE scope. These certifications help meet regulatory requirements and support safe, compliant installations.
For installation, plan for a 750 mm wide by 450 mm high enclosure with 225 mm built-in depth. The device uses a mounting plate with WR frame and offers 108 DIN place units to accommodate up to three devices. The 90-degree closure and plastic cover simplify field mounting and provide a stable, vibration-resistant fit within CombiLine interior fitting modules.
By standardizing on a single NH1 fuse switch disconnector in a 3-pole configuration, maintenance cycles shorten due to clear isolation points and fewer parts (no knife blade fuse holders). Field mounting uses a compact, lightweight 5 kg module that fits standard cabinet depths, reducing space and crane costs. The EN61439-compliant design also lowers compliance risk and accelerates time-to-operate, delivering lower total cost of ownership in panel upgrades.
