Description
- Model: Z-NTS
- Brand: ABB
- Part Type: Neutral Line Disconnector
- Rated Current: 3 A
- Poles: 1-pole
- Application: Electrical distribution and control-panel protection
Technical Introduction
The ABB Z-NTS is identified in ABB-related spare-parts documentation as a neutral line disconnector, with part number 3BH000630P10001. An archived U.S. government procurement record specifically lists this part as an ABB Neutral Line Disconnector for an ABB Azipod installation.
The Z-NTS designation also appears in Eaton/Moeller product documentation for a 3 A neutral line disconnector, so procurement teams should verify the complete ABB part number and equipment documentation rather than treating the short Z-NTS designation as sufficient identification.
Best Suited For
- ABB legacy equipment spare-parts inventory
- Replacement of an installed Z-NTS assembly where the complete part number matches
- Maintenance of electrical distribution or control-panel circuits
Core Technical Specifications
- Manufacturer: ABB
- Model: Z-NTS
- ABB Part Number: 3BH000630P10001
- Product Type: Neutral Line Disconnector
- Rated Current: 3 A
- Poles: 1-pole
The 3 A / 1-pole ratings are independently associated with the Z-NTS designation in current distributor documentation; confirm these values against the nameplate and OEM documentation for the ABB-specific assembly before installation.
Please refer to the OEM datasheet for complete electrical ratings, mounting requirements, environmental tolerances, dimensions, and applicable certification information.
ABB Z-NTS
Field Engineer’s Tech Notes
1. Verify the full ABB part number.
“Z-NTS” is not sufficiently specific for a controlled spare-parts database. Other manufacturers have used the same designation, including Eaton/Moeller. Match 3BH000630P10001, nameplate markings, and the existing electrical schematic before releasing a replacement.
2. Check the neutral-circuit arrangement before energizing.
A neutral-line disconnector is part of the circuit-isolation arrangement. Confirm conductor identification, terminal configuration, rated current, and the site’s isolation procedure. Do not substitute a visually similar DIN-rail device without verifying the electrical design.
Adaptive QA & Testing Protocol
For this type of electrical switching/disconnection component, inspection focuses on mechanical condition and electrical continuity rather than PLC firmware or communication testing.
The unit can be checked for correct identification, terminal condition, mechanical operation, visible damage, and appropriate continuity/open-state behavior using controlled electrical test equipment. Where applicable, the test procedure also verifies that the device does not show abnormal contact resistance or mechanical binding.
Inspection records, test reports, and available test videos can be provided upon request.
Buyer’s FAQ
Is ABB Z-NTS a PLC or DCS module?
No. It is identified as a neutral line disconnector, used within an electrical distribution/control arrangement rather than as a processor or I/O module.
Is Z-NTS a sufficient part number for procurement?
No. For an ABB replacement, use the complete identification where available. The archived ABB-related procurement record identifies the unit as Z-NTS P/N 3BH000630P10001.
Can another Z-NTS branded component be used as a replacement?
Not without engineering verification. The Z-NTS designation is also used for an Eaton/Moeller neutral line disconnector, so manufacturer and complete part number must be matched before substitution.
Is the unit new or refurbished?
Condition depends on the specific inventory lot. Confirm whether the offered unit is New Surplus (NSFP), used, or refurbished, and request inspection/test documentation when the part is being purchased as a critical maintenance spare.
