과부하 보호: adjustable electronic motor thermal overload protection

내장형 바이패스: 예; automatically switches to bypass operation after startup to reduce thyristor heating

장착 유형: 벽걸이형

보호 기능: 과전류, 위상 손실, 과열, phase sequence fault, 모터 과부하, thyristor failure, control supply loss

일반적인 응용 분야

워터 펌프, 원심 팬, belt conveyors and compressors.

Not applicable to frequent forward/reverse rotation or jogging operation. It suppresses starting inrush current, reduces grid voltage drop, and protects motors and mechanical equipment.

선택 & 교체 지침

1. For heavy starting loads (예를 들어, fans started under full load), verify the starting current and select one size up if necessary.
2. 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.
3. Same-platform alternatives:

같은 시리즈: PSE210-600-70 (fixed model)

Upgrade series: PSTX series (PSTX210) with enhanced functions, built-in communication and advanced protection

4. 의사소통: Basic PSE models have no native Modbus; an external communication module is required. PSTX models come with built-in Modbus RTU.

일반적인 문제 해결

Overheating alarm: Insufficient cabinet ventilation, dust accumulation, 높은 주변 온도; burnt bypass contacts cause thyristors to remain energized continuously.

Overcurrent fault on startup: Excessively high current limit setting; 기계적 방해; 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.

기계적인 설치 & 배선

배선: 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.

냉각: Natural air cooling; reserve upper and lower ventilation space; maintain gaps between multiple units installed side by side.

인클로저 등급: IP20 (실내 캐비닛 설치 전용).

Selection Schedule for ABB PSE210-600-70 (400 다섯, Motor Rated Current 210 에이)

메모: 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: 교류 400 다섯 / 50 헤르츠, 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 에이, built-in bypass contactor.

1. 성형 케이스 회로 차단기 (MCCB, ABB SACE)

기능: 단락 보호 + 전기 절연. Long-time delay setting shall be higher than motor rated current; overload protection is assigned to the soft starter.

2. 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

1. 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.
2. Siemens 3RW44: 내장형 바이패스, 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.
3. Eaton S811+: European equivalent with integrated bypass, widely adopted in overseas projects.
4. Delta VSS2: Taiwanese economical model with built-in bypass, high cost-performance for retrofitting ABB PSE in domestic projects.
5. 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)

1. 제어 공급: 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.
2. 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.
3. 의사소통: Only PSE models with suffix `-1` have native Modbus. Basic ATS22 units require an extra communication module; the same applies to Siemens models.
4. Cabinet Dimensions: Mounting depth and cutout dimensions differ across brands; verify mechanical dimensions before retrofitting existing cabinets.
5. 보호 논리: Fault relay contact ratings and actuation logic are not identical. Rewire PLC control and fault alarm circuits accordingly.
6. 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.
