The Schneider Electric LC1DT40 is a 4-pole AC contactor belonging to its TeSys Deca series. It is primarily designed for switching circuits on and off, and is suitable for scenarios requiring frequent or rapid power switching. Below is a detailed introduction:
- Основные технические параметры
| Parameter Category | Specific Details |
| Basic Electrical Parameters | Rated contact current: 40А; Maximum rated contact voltage: up to 690V AC. Available in multiple coil voltage versions, such as 24V DC, 120V AC, 230V DC, etc., to meet the requirements of different control circuits. |
| Structural Specifications | 4-pole configuration with a standard contact arrangement of 4 нормально открытый (НЕТ) main contacts, plus 1 НЕТ + 1 normally closed (Северная Каролина) auxiliary contact as standard; the NC contact is mirror-certified. Compact dimensions for easy installation: 45мм в ширину, 91mm in length, and 107mm in depth. |
| Экологическая адаптивность & Durability | Диапазон рабочих температур: -40°C to +60°C, suitable for harsh working conditions. Mechanical durability: up to 30 миллион операций. Breaking capacity at 440V: 450А, which prevents equipment damage caused by inrush current during startup and reduces maintenance frequency. |
- Core Features
Comprehensive Safety Protection: Equipped with a built-in protective cover to prevent contamination from airborne particles and accidental electric shock. Front protection rating reaches IP20, complying with the IEC 60529 стандартный. Integrated bidirectional peak-limiting diode suppressor protects the coil from surge current impact.
Flexible Installation & Wiring: Supports two installation methods—DIN rail mounting and panel mounting—to adapt to different application scenarios. Adopts screw-clamp terminals for secure wire connection, minimizing the risk of loose contacts.
Fast Switching Response: Disconnection time ranges from only 16–24ms, enabling near-instantaneous circuit switching. Ideal for devices requiring high switching speed, such as motor starters.
- Certification & Compliance
This model has obtained a number of domestic and international authoritative certifications, including CCC, UL, CSA, МЭК, DNV, and Lloyd’s Register certification. It complies with standards such as CSA C22.2 No.14, EN 60947-4-1, и МЭК 60335-1. Тем временем, it meets Green Premium certification requirements and complies with RoHS/REACH environmental regulations, making it suitable for market access in multiple countries.
- Типичные сценарии применения
Thanks to its high reliability and resistance to harsh environments, it is widely used in complex working conditions such as shipyards and quarries. It is also applicable to industrial sectors including oil and gas, and pharmaceuticals. Typical applications include circuit control for equipment such as motor starters and large-scale industrial lighting systems.
- Compatible Accessories & Expandability
It can be paired with a variety of dedicated accessories to expand its functionality, such as serrated wiping action auxiliary contact modules, dust-proof front-mounted auxiliary contact modules, pneumatic time-delay modules, and transient voltage surge suppressors. In addition, it is directly compatible with LRD series overload relays, and LADN auxiliary contact modules can be mounted on top to flexibly increase the number of contacts and meet diverse control requirements.
