NZM2-XTVD
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.
