選択 & 交換ガイドライン
- For heavy starting loads (例えば, fans started under full load), verify the starting current and select one size up if necessary.
- PSE has an integrated bypass; cabinet heat dissipation shall be designed based on continuous heat generation of the bypass contactor, not only thyristor power loss.
- Same-platform alternatives:
同じシリーズ: PSE210-600-70 (fixed model)
Upgrade series: PSTX series (PSTX210) with enhanced functions, built-in communication and advanced protection
- コミュニケーション: Basic PSE models have no native Modbus; an external communication module is required. PSTX models come with built-in Modbus RTU.
よくあるトラブルシューティング
Overheating alarm: Insufficient cabinet ventilation, dust accumulation, 周囲温度が高い; burnt bypass contacts cause thyristors to remain energized continuously.
Overcurrent fault on startup: Excessively high current limit setting; 機械的な妨害; short circuit in motor insulation or power cables.
Phase loss alarm: Blown incoming fuses, loose main circuit wiring, damaged internal thyristors.
Bypass switching failure: Defective bypass contactor coil or auxiliary contacts.
機械的設置 & 配線
配線: Three-phase power input L1/L2/L3; output terminals connect directly to the motor. Control terminals connect to start/stop signals and fault relay output.
冷却: 自然空冷; reserve upper and lower ventilation space; maintain gaps between multiple units installed side by side.
Enclosure rating: IP20 (indoor cabinet installation only).
Selection Schedule for ABB PSE210-600-70 (400 V, モーター定格電流 210 あ)
注記: PSE210 has built-in bypass and integrated electronic motor overload protection. Upstream components only provide short-circuit protection, while motor overload protection is fully undertaken by the soft starter. System conditions: 交流 400 V / 50 Hz, copper power cables, free air installation, ambient temperature 30~35 °C, standard fan/pump loads.
Soft starter rating: PSE210-600-70, Ie=210 A, maximum main circuit withstand current 600 あ, built-in bypass contactor.
- 配線用遮断器 (MCCB, ABB SACE)
関数: 短絡保護 + electrical isolation. Long-time delay setting shall be higher than motor rated current; overload protection is assigned to the soft starter.
| アイテム | 推奨スペック | 備考 |
| モデル | T6N 630 TMA 3P | ABB OEM recommendation; フレームサイズ 630 あ, TMA thermal-magnetic trip; 短絡遮断容量 10 の. Upgrade to T6H (20 の) if prospective short-circuit current exceeds 10 の. |
| 定格電流入力 | 630 あ | Instantaneous trip: 10×In to avoid tripping during current-limited soft start. |
| トリップ設定 | Long delay: 250 あ (調整範囲); 瞬時: 10×イン | Do not rigidly set to 210 あ; retain sufficient margin for starting surge. Overload protection is undertaken by the PSE soft starter. |
| 国内代替品 | NM1-630/3P 630 あ, 熱磁気トリップ | Cost-effective option for budget-limited projects. |
- Fuse Solution (Short-Circuit Protection without MCCB)
Suitable for upstream fuse protection inside the cabinet; gG general-purpose fuses. Verify I²t coordination to protect soft starter thyristors.

Brand Position Comparison
- Schneider ATS22: First choice for direct replacement. It has identical positioning, built-in bypass and matching protection functions. ATS48 / ATS480 have no built-in bypass; an external contactor must be fitted, which raises total cost.
- Siemens 3RW44: 内蔵バイパス, direct counterpart to PSE. Basic 3RW40 models have no bypass and are prone to misselection. 3RW55 is the new generation with enhanced performance and higher price as an upgraded alternative.
- Eaton S811+: European equivalent with integrated bypass, widely adopted in overseas projects.
- Delta VSS2: Taiwanese economical model with built-in bypass, high cost-performance for retrofitting ABB PSE in domestic projects.
- CHNT NJR2 / DELIXI CDRAK3: Domestic economical options. Must select the built-in bypass variant; standard NJR2 requires an external bypass contactor.
Critical Notes for On-site Replacement (Engineering Compliance)
- 制御電源: PSE accepts AC 100~240 V. ATS22 / 3RW44 support AC 110~230 V, which is fully compatible. Some domestic models only support AC 220 V and cannot be used if only 110 V control power is available.
- Starting Principle: PSE adopts two-phase thyristor control; ATS22 and 3RW44 use three-phase control. The difference in starting performance is negligible for pumps and fans; adjust ramp parameters on-site for heavy inertia loads.
- コミュニケーション: Only PSE models with suffix `-1` have native Modbus. Basic ATS22 units require an extra communication module; the same applies to Siemens models.
- Cabinet Dimensions: Mounting depth and cutout dimensions differ across brands; verify mechanical dimensions before retrofitting existing cabinets.
- 保護ロジック: Fault relay contact ratings and actuation logic are not identical. Rewire PLC control and fault alarm circuits accordingly.
- Heavy-duty Loads: For crushers and high-inertia belt conveyors, select one current size up instead of strictly matching the rated current in the table.
