Full Ordering Code Example NZM1-4-XFIU230AC (This would specify a 230V AC operating voltage for the shunt trip/UVR coil). The voltage must be specified.
Components Included • 1x Shunt Trip/Under-Voltage Release (XF)
• 1x Auxiliary Contact (I): Specific configuration (e.g., 1 NO + 1 NC)
• 1x Alarm Contact (U): 1 NO (on fault trip only)
Shunt Trip/UVR Voltage Available for common AC voltages (e.g., 230V, 400V AC). Must be specified in full order code.
Auxiliary & Alarm Contact Rating Suitable for control circuits. Typical rating: e.g., 3A @ 230V AC (AC-15). Must be verified from datasheet.
Standards Compliance As part of the breaker assembly, it helps comply with IEC 60947-2.
The Eaton NZM1-4-XFIU is a pre-assembled combination accessory module designed specifically for 4-pole circuit breakers of the NZM1 frame size within Eaton's NZM series.
