LPC
LPC (Low Power Contactors) are compact electromechanical switching devices designed for controlling electrical loads in industrial and commercial applications. These contactors typically feature 3-pole or 4-pole configurations, with rated operational currents ranging from 9A to 65A, and coil voltages available in AC (24V to 690V) and DC (12V to ...
LPC (Low Power Contactors) are compact electromechanical switching devices designed for controlling electrical loads in industrial and commercial applications. These contactors typically feature 3-pole or 4-pole configurations, with rated operational currents ranging from 9A to 65A, and coil voltages available in AC (24V to 690V) and DC (12V to 220V) variants. They are engineered for high electrical endurance, with mechanical life exceeding 10 million operations, and incorporate arc suppression chambers for reliable switching under inductive loads. LPCs are available with screw, spring-cage, or ring-tongue terminal connections, and can be equipped with auxiliary contact blocks (1NO+1NC to 4NO+4NC) for signal feedback. Their compact footprint (typically 45mm to 90mm width) makes them ideal for space-constrained control panels, while their IP20 protection rating ensures safe operation in dry environments.
LPCs are predominantly installed in motor control centers (MCCs), distribution boards, and automation panels for switching motors, resistive loads, and lighting circuits. They are widely used in HVAC systems (compressors, fans, pumps), conveyor belts, packaging machinery, and water treatment plants. In industrial automation, they serve as primary switching elements in star-delta starters, reversing starters, and direct-on-line (DOL) motor starters. Their ability to handle high inrush currents (up to 10x rated current) makes them suitable for capacitor bank switching and transformer primary control. Additionally, they are employed in elevator controls, crane systems, and renewable energy installations (solar inverters, wind turbine pitch control).
Key subcategories within the LPC range include standard power contactors (e.g., 3-pole 9A, 12A, 18A, 25A, 32A, 40A, 50A, 65A models), reversing contactors (mechanically interlocked pairs), and capacitor switching contactors (with damping resistors). Typical article codes follow a pattern like LPC-09-01-24 (where 09 indicates current rating, 01 denotes pole count, and 24 specifies coil voltage). Popular models include LPC-12-03-230VAC, LPC-25-04-24VDC, and LPC-40-03-400VAC. These are often supplied with matching thermal overload relays (e.g., LPC-TOR-09-12) and mechanical interlock kits for reversing applications.
Partnering with Electric Automation Network ensures access to genuine LPCs at competitive prices (up to 65% discount vs. list price) with real-time stock visibility and express shipping (24-48 hours to major global hubs). Our engineering team provides tailored support for contactor selection, coil voltage matching, and auxiliary contact configuration. Each product includes detailed technical datasheets, CAD drawings, and compliance certificates (CE, UL, CCC). We offer volume discounts for OEMs and system integrators, with dedicated account management for large-scale projects.
