- Рекомендации по выбору & Решения по замене
5.1 Ключевые параметры выбора
| Параметр | Ключевые моменты выбора | Recommended Specification |
| Rated Current Matching | Contactor rated current ≥ motor rated current (АС-3 дежурство) | 25A contactor suitable for ≤11kW/380V motors |
| Конфигурация вспомогательного контакта | Select NO/NC quantity according to control circuit demand | Стандартный 01(1Северная Каролина); Normally Open select 10(1НЕТ); More contacts select 22 |
| Выбор напряжения катушки | Consistent with control circuit voltage | Industrial common: 220В и(M5); Safety voltage: 24В Вашингтоне(B5) |
| Способ монтажа | Determined by control cabinet layout | Монтаж на DIN-рейку (стандартный); Screw mounting for limited space |
| Protection Requirement | Need for overload protection and interlock function | Motor control must match LRN thermal relay; Reversible control requires interlock accessory |
| Рабочая частота | High-frequency start-stop occasion requires high-cycle model | Стандартный 1200 cycles/hour; Ultra-high frequency choose LC1D series |
5.2 Рекомендации по замене
Current rating mismatch:
Motor power ≤7.5kW: Select LC1N1801 (18А)
Motor power 15kW: Select LC1N3201 (32А)
Insufficient auxiliary contacts:
Add LANN series auxiliary contact block, expandable up to 2NO+2NC maximum
Different control voltage:
24V DC control: LC1N2501B5N
380V AC control: LC1N2501Q5N
Higher performance required:
Choose LC1D2501 (TeSys D series), mechanical life 10 миллион циклов, electrical life 2 миллион циклов, stronger vibration resistance
Budget limited:
Adopt domestic alternatives such as Chint CJX2-2501, Delixi CJX2S-2501; similar performance with price reduced by about 30-50%
5.3 Application Precautions
- Confirm coil voltage matches control circuit before installation to avoid coil burnout.
- Fasten main circuit wiring with recommended torque 1.85N·m to prevent overheating and poor contact.
- When directly plugging with LRN series thermal relay, ensure complete latch locking to prevent loosening by vibration.
- Reversible control circuit must be equipped with LA9D09978C mechanical interlock to prevent phase-to-phase short circuit.
- It is recommended to parallel surge suppressor at both ends of the coil to protect PLC/relay contacts in control circuit.
- When ambient temperature exceeds 40°C, derate rated current (10% reduction per additional 10°C rise).
- Regularly check contact ablation; replace contactor when main contact wear exceeds 1mm.
