This RJSPHH replacement part—compatible with part numbers A0004499959 and 10000004183—measures 6.1 in x 3.1 in and is built to snap into existing ATS control locations. It provides a like-for-like replacement to get your transfer switch back to reliably sensing and shedding loads when necessary. The module ships with a one-year warranty and technical support within 24 hours for installation or compatibility questions.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this module fix an ATS that won't transfer?\u003c\/h3\u003e\n\n\u003cp\u003eWhen an ATS fails to transfer, it may be because the load-shed module no longer communicates with the transfer switch logic or has developed internal faulting. Replacing the module restores the control circuitry that senses utility status and commands the ATS contactor to switch to generator power. Install is generally straightforward for qualified technicians and returns the ATS to normal automatic operation.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDirect replacement for Generac part numbers A0004499959 and 10000004183\u003c\/li\u003e\n  \u003cli\u003eRestores transfer switch control and load-shedding signals\u003c\/li\u003e\n  \u003cli\u003eFits 100-amp and 200-amp Generac ATS configurations\u003c\/li\u003e\n  \u003cli\u003eSaves time over diagnosing multiple ATS subcomponents\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the physical and electrical specifics I need to know?\u003c\/h3\u003e\n\n\u003cp\u003eThe RJSPHH SACM comes in a compact module sized 6.1 in x 3.1 in that aligns with the mounting and connector locations of compatible Generac transfer switches.
