Key Parameters Category Description / Value Product Line Eaton NZM2 Model Type XTVD (Denotes the DC-operated version) Rated Current (Iₙ) Available from 63 A to 320 A (Specific value is part of the order code, e.g., NZM2-XTVD 160). Number of Poles 1P, 2P, 3P, 4P Rated Insulation Voltage (Uᵢ) 1000 V Rated Impulse Withstand Voltage (Uᵢₘₚ) 12 kV Rated Operational Voltage (Uₑ) - DC Up to 1000 V DC (The maximum voltage depends on the number of poles. e.g., a 2-pole breaker is typically rated for 1000V DC). Rated Ultimate Short-Circuit Breaking Capacity (I꜀ᵤ) - DC Up to 50 kA (at specified DC voltages, e.g., 50 kA @ 500 V DC). The value is voltage-dependent. Release Type Thermal-Magnetic (TMD) • Magnetic Trip (Instantaneous) For short-circuit protection. Often adjustable (e.g., 5...10 × Iₙ). • Thermal Trip (Long Delay) For overload protection, following an I²t characteristic. Standards Compliance IEC/EN 60947-2 Terminals Suitable for front and rear connection. Accepts copper or aluminum cables (refer to manual for torque specifications). Operating Mechanism DC Operating Mechanism (optimized for breaking DC arcs). Available Accessories • Auxiliary Contacts (OF, SD) • Undervoltage Release (UV) • Shunt Trip (ST) • Rotary Handle Operator • Padlockable Handle Locks
