ASCO Power Technologies (Cummins)
ASCO Power Technologies (Florham Park, NJ; subsidiary of Cummins Inc. since 2017; previously Emerson Electric 2011-2017) is the heritage American ATS brand founded in 1888 in Newark, NJ — the company that supplied the first automatic transfer switch for hospital backup power and established the design concepts that all ATS manufacturers follow today. ASCO's 7000 Series Transfer Switches (100A to 4,000A) are the dominant ATS brand in U.S. hospitals and critical government facilities. ASCO also makes the 4000 Series (residential/light commercial), 5000 Series (service entrance rated), and the 7000 Series Open-Transition, Closed-Transition, and Soft-Transfer variants. As a Cummins subsidiary, ASCO benefits from integration with Cummins generator sets — a genset + ASCO ATS package is standard in U.S. hospital backup power procurement. Essentially all U.S. hospital generator backup systems use ASCO or a competitor design derived from ASCO's original 1888 concepts.

ASCO Power Technologies was founded in 1888 in Newark, New Jersey — making it the oldest ATS manufacturer in the world and the company that invented the modern hospital automatic transfer switch. The original ASCO 'Automatic Switch' was designed to switch hospital operating rooms between two power sources without interruption. ASCO's design — contactor-based open transition switching with an automatic detection circuit — became the template for every ATS product from every manufacturer that followed. Today, virtually all U.S. hospitals that have generator backup use either an ASCO 7000 Series or a competitor ATS that was designed to meet the NFPA 99 Healthcare Facilities Code specifications that ASCO helped author. The ASCO 7000 Series is also specified in essentially all FEMA Emergency Operations Centers, USACE-designed military base power systems, and federal critical infrastructure protective systems. A company founded 136 years ago to switch Newark hospital operating room power now sits in the critical path of the U.S. military's backup power resilience.

ASCO Power Technologies (American Switch Company) was founded in 1888 in Newark, New Jersey — just five years after Thomas Edison launched his first commercial DC electric grid in Manhattan (Pearl Street Station, 1882). ASCO was among the first companies to make switching equipment for the newly electrifying US, eventually inventing the automatic transfer switch — the device that automatically disconnects a building from the grid and connects it to a backup generator. ASCO's 1888 founding in Newark (then a leading US industrial city) and its role in creating the ATS product category make it the oldest brand in the critical power infrastructure supply chain. Cummins acquired ASCO in 2017 for $1.2 billion after acquiring ASCO from Emerson Electric.
