Product Introduction

K1152132 is a high-performance panel-mount power and signal relay from TE Connectivity, part of the classic TE KISSLING series. Designed for on/off control, signal transmission, and circuit protection in medium to high current circuits, it combines mature electromechanical control and premium materials to deliver high load capacity, stability, and versatility. It is a foundational electrical component for industrial control, new energy, and electrical equipment.

K1152132 is engineered to “control high current with low signal”: a low-power coil signal precisely switches 75 A high-current circuits, effectively isolating low-voltage control circuits from high-current loads to avoid damage to control modules. It features a single-pole single-throw (SPST) contact structure for simple, accurate control. Panel mounting fits cabinet and equipment embedded assembly for high adaptability. Contacts use silver tin oxide, which outperforms pure silver in arc resistance, oxidation resistance, and wear resistance, greatly extending service life for frequent switching in tough environments. With moderate coil power consumption, high stability, and strong anti-electromagnetic interference, it operates reliably in standard industrial and civilian electrical systems for broad power control and signal transmission use. Samples and real-time inventory are available through SMCC and other authorized TE distributors to ensure stable supply chains for R&D and mass production.

Industry Applications

Industrial Automation

In industrial automation equipment, K1152132 is a core control component for motors, fans, pumps, heaters, and other actuators. It receives low-voltage signals from PLCs and controllers to switch high-power circuits, enabling automated start/stop and mode changes. Silver tin oxide contacts withstand frequent starts and transient current surges, avoiding contact erosion and poor connection to ensure stable long-term operation of lines and standalone machines.

New Energy Electrical

In distributed PV, small energy storage, and new energy supporting electrical systems, K1152132 controls and protects DC distribution and battery charge/discharge circuits. New energy systems have large current fluctuations requiring high load capacity and stability. The 75 A rating covers small to medium storage and PV systems; excellent arc resistance handles current swings, preventing overload and short-circuit failures. Low coil power reduces self-consumption, improving generation and storage efficiency for residential PV, small commercial storage, and new energy control cabinets.

Smart Buildings

K1152132 is used for high-power load control in smart building ventilation, lighting master control, water pumps, fire-supporting electrical systems, and small municipal public facilities. It enables timed and intelligent linked control of public lighting, fans, and water equipment. It adapts to standard temperature and humidity in building equipment rooms and municipal cabinets, runs quietly and reliably, and fits standard building electrical cabinets via panel mounting. With low failure rates and maintenance costs, it ensures long-term safe and stable building electrical systems.
