The Schneider Electric TeSys SK series represents a pinnacle of miniature control technology, specifically engineered for space-constrained industrial environments. These ultra-compact mini-contactors are designed for high-reliability switching of motor control and resistive loads, providing a robust interface between control circuits and power-hungry equipment.
The TeSys SK range (predominantly the LC1SK series) is widely regarded for its exceptional power-to-size ratio. With a standard width of just 27mm, these units are ideal for high-density DIN rail mounting in electrical cabinets where space is at a premium. They are fully compliant with international standards including IEC 60947, BS 5424, and VDE 0660, ensuring they meet the stringent safety requirements of the UK and European markets.
- Current Ratings: Optimized for non-inductive loads up to 12A (AC-1) and single-phase motor control up to 6A (AC-3).
- Voltage Compatibility: Supports operational voltages up to 690V AC, making them versatile for various industrial grids.
- Coil Voltages: Available in a wide array of AC control circuit voltages (e.g., 24V, 110V, 230V) to match standard automation logic.
- Pole Configuration: Typically available in 2-pole (2 NO) configurations, with the ability to expand to 3-phase motor control through the use of LA1SK add-on contact blocks.
- Operational Durability: Built for high-frequency switching, capable of handling up to 1,200 cycles per hour with a mechanical life of up to 10 million cycles.
Key Features & Benefits
