FAQs
NZMB2-4-A200 uses a four-pole design within the NZM2 frame and features front screw connections for straightforward wiring. Its compact footprint (5.51 in depth, 5.86 in height and width) and 200 A rating align with common panel layouts, facilitating quick integration into distribution boards and motor control centers.
The device provides a 200 A amperage rating, 600 Vac voltage rating, and a short-circuit breaking capacity of 25 kAIC. It uses a T185 trip type with an adjustable short‑circuit release (1200–2000 A, delayed) and an OL protector setting of 160–200 A to enable selective coordination in complex distributions.
Front-screw termination allows easier wiring access, faster assembly, and cleaner terminations, which reduces installation time and helps when retrofitting in crowded or retrofit panels. This design also supports reliable front-access maintenance without disassembling the enclosure.
Ideal for motor control centers and distribution panels in manufacturing, processing, and HVAC systems. The four-pole configuration provides balanced protection for three‑phase loads, while the 200 A rating and 25 kAIC capacity support high-demand equipment and critical loads in industrial environments.
