The Schneider LA1KN31 is an auxiliary contact block designed to provide additional signaling and control logic for power contactors. In Indian industrial automation, it is commonly used for electrical interlocking, remote status indication (ON/OFF), and PLC feedback to ensure safe motor operation.
The LA1KN31 model is specifically designed for a particular range. For instance, LA1K series are for TeSys K (compact) contactors, while LADN/LAD8 series are for TeSys D/Deca contactors. It is essential to verify the frame size to ensure a secure mechanical snap-on fit within your control panel.
The LA1KN31 features high-reliability contacts rated for standard industrial control voltages used in India, such as 110V, 230V, or 415V AC. It is engineered to handle low-level switching currents (typically up to 10A thermal current) with high mechanical durability exceeding millions of cycles.
By adding the LA1KN31 to your power contactor, you can implement safety interlocks that prevent simultaneous operation of conflicting loads. Its finger-safe (IP20) terminal design complies with international safety standards, protecting maintenance personnel in Indian factories from accidental contact with live parts.
The LA1KN31 features a modular, tool-free 'clip-on' mounting mechanism. It can be easily mounted on the front or side of the compatible contactor. In the Indian context, this modularity allows for quick field upgrades and reduces downtime during panel maintenance or logic modification.
The Schneider LA1KN31 features a conventional thermal current (I_{th}) of 10A at \le 50^\circ C, adhering to IEC 60947-5-1. This ensures high-performance signaling in compact TeSys K control circuits used in Indian panel boards.
The LA1KN31 is rated for AC-15 (600V AC) and DC-13 (600V DC) utilization categories. It provides reliable switching for control coils and signaling lamps across a wide operational voltage range from 17V to 690V AC/DC.
Equipped with high-conductivity contacts, the LA1KN31 has a minimum switching current of 5mA and a minimum switching voltage of 17V. This technical specification prevents signal loss when interfaced with modern PLCs and electronic controllers.
The LA1KN31 auxiliary block is designed for heavy-duty industrial use, offering a mechanical durability of 5 million cycles. This ensures long-term maintenance-free operation in demanding Indian manufacturing environments.
The LA1KN31 uses screw clamp terminals designed for a tightening torque of 0.8 N.m to 1.3 N.m. It accommodates flexible cables up to 1.5mm^2 or rigid cables up to 4mm^2, ensuring secure electrical terminations.
