Comparing the Chint NM1 and the ABB Tmax T1 moulded case circuit breaker (MCCB)? Both are IEC 60947-2 devices for distribution and feeder protection. The ABB T1 is a compact 160A frame; the Chint NM1 series scales higher. Here is how they stack up.
Chint NM1 vs ABB Tmax T1 — Comparison Table
| Attribute | Chint NM1 | ABB Tmax T1 |
|---|---|---|

Frequently Asked Questions
Can the Chint NM1 replace an ABB Tmax T1?
For equivalent ratings they are both IEC 60947-2 thermal-magnetic MCCBs, so the NM1 is a functional equivalent. Verify the frame size, breaking capacity (Icu) and trip settings against your design.
What is the difference in breaking capacity?
The ABB Tmax T1 offers up to ~25kA at 400V in its 160A frame; Chint NM1 ratings vary by size and reach up to ~50kA. Always match Icu to the prospective fault current at the board.
What is the NewTrend equivalent MCCB?
NewTrend supplies its own CM1 MCCBs (to 1600A) plus genuine Chint NM1/NXM and Delixi CDM3s. See our cross-reference chart for exact model mapping.
