Product English Introduction：
The Auxiliary Contact Left (Lead-out) M3-100FN 1K1B is a modular expansion component specifically designed for electrical control systems. Featuring left-side lead-out configuration, this product seamlessly integrates with various main control devices to enhance system functionality. Its compact structural design optimizes space utilization while maintaining full operational capability, making it particularly suitable for installation in confined spaces such as power distribution cabinets.
Constructed with high-elasticity copper alloy contacts, the product demonstrates excellent electrical conductivity and mechanical durability. The contact surfaces undergo specialized treatment to form a uniform wear-resistant conductive layer, ensuring stable electrical connection even under frequent operation. The insulated base utilizes high-temperature resistant engineering plastic that maintains stable physical properties within a temperature range of -25℃ to +85℃. The modular plug-in design simplifies installation procedures and supports tool-free assembly, significantly improving maintenance efficiency.
In terms of electrical performance, optimized contact pressure distribution and gap control effectively reduce contact resistance, keeping temperature rise within safe parameters during normal operation. The double-break contact structure combined with arc-extinguishing grooves effectively suppresses arc generation during switching operations, extending product service life. Lead terminals incorporate anti-loosening mechanisms to ensure long-term connection reliability. Clear functional markings on the housing facilitate quick identification and circuit verification during installation.
This product finds extensive application in industrial automation production lines, building power distribution systems, and machinery control cabinets. It is particularly suitable for expanding control circuits in AC contactors and relays, providing flexible configuration options to meet diverse auxiliary contact requirements. The modular design allows functional expansion according to specific system needs, offering reliable solutions for upgrading electrical control systems.
