Official Overload Capacity Parameters of ACS880-01-246A-4 (Standard Operating Conditions: 40 °C Ambient Temperature, Altitude ≤1000 m)

The overload capacity of this model is divided into two operation modes based on load characteristics: Light Overload (Variable Torque VT) and Heavy Overload (Constant Torque CT). All overload cycles last 5 minuti, with a hardware-limited instantaneous maximum current ceiling. The marking `246A` represents the VFD’s rated output current; voltage suffixes such as -3/-4 do not alter overload current parameters, only the matching motor power.

Key Supplementary Explanations

1. Hardware Current Limit Constraint: The peak output current of all operating scenarios is capped by IGBT hardware at maximum 350 UN; IL 150% overload current of 309 A under heavy-duty mode is below this ceiling and fully deliverable.
2. Derating Rules:

If ambient temperature exceeds 40 °C, the rated output current is derated by 1% per 1 °C rise (max withstand temperature 60 °C), with synchronous reduction of overload capacity.

If installation altitude exceeds 1000 M, the rated output current is derated by 1% per 100 m elevation gain.

3. Meccanismo di protezione: When overload duration or current exceeds specifications, the VFD will trigger an overload warning first; sustained violation will lead to `F0011` motor overload trip, combined with heatsink overtemperature protection for dual safety coverage.
4. Cambio di modalità: The two overload modes can be switched via parameter `22.02`. The selected mode must match actual load characteristics; prolonged operation beyond rated overload specifications accelerates aging of power components.

Reference Unit: ACS880-01-246A-4

Core Reference Specifications: 380~500 V wide voltage, 132 kW CT heavy duty, heavy-duty rated current 206 UN, 150% sovraccarico per 60 S; 160 kW VT light duty, light-duty current 234 UN, 110% sovraccarico per 60 S; built-in DC reactor + Filtro EMC + chopper di frenatura + STO safety function.

1. High-End Foreign Brand Counterparts (Original Imported / Top European & American Brands, Direct Replacement for Heavy-Duty Applications)

1. Domestic High-End Industrial Counterparts (Domestic Replacement with Equivalent Performance & Lower Cost)

1. Key Replacement Selection Differences & Risk Warnings
2. Critical Voltage Matching Notes

Reference ACS880-01-246A-4: 380~500 V wide voltage, dedicated for export and overseas 480 V equipment;

The equivalent current model for standard domestic 380 V applications is ACS880-01-246A-3 (380~415 V).

For replacement selection, all matching models must carry suffix 4 (400 V wide voltage); narrow-range 380 V models are forbidden.

2. Built-in Hardware Differences (Key Points for Retrofit Replacement)
3. Standard built-in configuration of ABB ACS880: DC reactor + Class C3 EMC filter + chopper di frenatura + STO
4. Siemens G120C and Schneider ATV630 come with standard STO, but DC reactors are mostly optional and must be purchased separately for replacement to avoid excessive harmonic distortion.
5. Domestic MD880/CH2000 series feature built-in braking units, while DC reactors are optional for partial specifications.
6. Core Overload Capacity Comparison (Mandatory for Heavy-Duty Applications)

ABB Reference: CT heavy-duty baseline current 206 UN, 150% sovraccarico (309 UN) sustainable for 60 S

All high-end counterpart models (G120C / ATV630 / GA800 / MD880) deliver equivalent overload performance with heavy-duty current ranging from 202 A a 208 UN

Economical ATV340 / G120XA lack the 150% heavy-duty profile and only support 110% light overload, leading to frequent tripping under impact loads.

4. Riferimento alle dimensioni di installazione

ACS880-01-246A-4 is R8 frame (963 × 681 × 386 mm, 58.6 kg).

Siemens G120C and Schneider ATV630 models of identical power have smaller footprints with no cabinet expansion required for retrofits; domestic MD880 dimensions are close to ABB, allowing shared mounting cutouts.

1. Quick Selection Conclusion
2. Industria pesante / Mixing / Trasmettere / Sollevamento (Constant Torque Heavy Duty): Prioritize Siemens G120C, Schneider ATV630 and Inovance MD880 for fully equivalent replacement in current rating, overload capacity and functions.
3. Export Equipment / Overseas 480 V Power Supply: Must select wide-voltage models with suffix -4; narrow-range 380 V units are prohibited.
4. Tifosi & Pompe (Light Duty Without Impact): Economical ATV340 and G120XA are available at lower cost.
5. Demand for Original Same Platform, DTC Control and Factory Integrated Solution: Directly adopt the same series ACS880-01-246A-4.
