Specifications Parameter Specification Product Range / Series Compact NSX (Formerly known as Multi 9 / Compact NS) Device Type Molded Case Circuit Breaker (MCCB) Model / Catalog Reference EZD250E Number of Poles 4-Pole (4P) Rated Operational Current (Iu) 200 Amperes (A) Rated Ultimate Breaking Capacity (Icu) @ 415V AC E型 - Typically 36 kA (for EZD...E version). Icu values vary by voltage and model suffix. Rated Service Breaking Capacity (Ics) Typically 100% of Icu (for this range). Rated Insulation Voltage (Ui) 690V AC / 750V DC Rated Operational Voltage (Ue) 690V AC / 250V DC Rated Frequency 50/60 Hz Trip Unit Type Micrologic 2.0 - 6.0 E (Thermal-Magnetic, Fixed or adjustable). The specific trip unit (e.g., Micrologic 2.0 MA, 5.0E, etc.) is a separate selection that defines the protection settings. Standard IEC/EN 60947-2 Electrical Life Up to 8,000 cycles at rated current. Mechanical Life Up to 20,000 cycles. Terminals Front or rear connection, suitable for copper or aluminum busbars/cables (specific sizes depend on configuration). Mounting Fixed, Plug-in, or Drawout versions available. Width Varies by configuration, but for a 4P EZD250E, it is typically ~144mm (4 x 36mm modules).
