Selection Guide
Use the following criteria to confirm the NZMN4-AE1000 is the correct model for your application:
| Parameter | Your Requirement | NZMN4-AE1000 Value |
|---|---|---|
| Rated Current | ≤ 1000 A | 1000 A |
| Number of Poles | 4P (3P+N or 4P) | 4P |
| System Voltage | ≤ 690 V AC / ≤ 250 V DC | 690 V AC / 250 V DC |
| Required Icu | ≤ 50 kA @ 415 V | 50 kA @ 415 V |
| Trip Function | Thermal-magnetic or electronic | AE = adjustable electronic |
| Mounting Style | Fixed or plug-in | Both supported |
| Standards | IEC / EN | IEC 60947-2 ✓ |
If your application requires higher breaking capacity, consider the NZMH4-AE1000 (H-frame, higher Icu). For lower current ratings, refer to the NZM3 or NZM2 series.

Replacement & Compatibility FAQ
Q: Can I replace NZMN4-AE1000 with NZMH4-AE1000?
A: Yes. The NZMH4-AE1000 is a higher breaking capacity variant in the same NZM4 frame. It is a direct mechanical and electrical upgrade, fully backward compatible.
Q: Is the Siemens 3VA2710 a direct drop-in replacement?
A: Functionally equivalent in rating, but bus bar hole patterns and terminal dimensions differ. Panel modifications may be required.
Q: What is the difference between NZMN4 and NZMH4?
A: NZMN4 = Standard breaking capacity (N-frame, ~50 kA). NZMH4 = High breaking capacity (H-frame, ~85 kA). Same current rating, different Icu.
Q: Does Konmask.com provide test reports or certificates of conformity?
A: Yes. COC and available test documentation can be provided upon request for qualified orders.
Q: What is the lead time for NZMN4-AE1000?
A: Typically 3–10 business days depending on stock availability. Contact us for real-time inventory status.
