Key benefits Continuous power without manual intervention: Automatically switches between utility and generator power to minimize downtime and keep critical systems running. Easy integration and installation: 35mm rail mounting lets you install the unit quickly in standard distribution panels and control cabinets. Reliable handling of moderate loads: Rated for 100A and designed for twopole circuits, it supports common singlephase backup setups and small commercial loads. Compatible control voltage: AC 110V control input matches common generator and control system voltages for straightforward wiring and operation. What this product does This 2P automatic transfer switch provides automatic changeover between two power sources, typically mains and generator. When the primary source fails, the device transfers the load to the standby source and returns it when the primary is restored. The unit is intended for mounting on a 35mm rail and operates with a 110V AC control signal. Its 100A current rating makes it suitable for many residential and light commercial applications. Key features Function: Automatic transfer switch for generator and mains changeover Poles: 2P for twopole circuit switching Mounting: 35mm rail mounting for panel or cabinet installation Control voltage: AC 110V Current rating: 100A How it solves common problems Eliminates the need for manual changeover, reducing response time during power failures. Simplifies wiring and panel layout with rail mounting and compact form factor. Handles sufficient current for typical home and small business backup loads without complex arrangements. Practical use scenarios Home backup system: Integrate with a standby generator to maintain lighting, refrigeration, and essential outlets during outages. Small commercial site: Keep pointof systems, security gear, and critical lighting powered at retail or small office locations. Remote equipment cabinet: Provide automatic source switching for telecom or monitoring equipment housed in control cabinets. Installation notes Designed for standard 35mm rail installation in breaker panels and control cabinets. Intended for twopole circuits and a 110V AC control input. Match wiring and protection devices to the 100A rating and local electrical codes. This automatic transfer switch is a practical component for anyone needing dependable automatic changeover between mains and generator power in 35mm rail mounted electrical panels.
