Automatic Double Power Transfer Switch 4Pole 100A, 110VAC/220VAC options Keep critical equipment running automatically when utility power fails. This 4 pole, 100A automatic transfer switch provides ultrafast switching between two power sources in 0.05 seconds, protecting sensitive systems from interruption during outages or generator startup. Key benefits Uninterrupted power: Automatic transition between primary power and backup generator in 0.05 seconds to minimize downtime. capacity: 100A rated current handles heavy residential and light commercial loads. Secure connections: 4 pole design ensures reliable connection of double power inputs for safe transfer of all conductors. Flexible voltage compatibility: Available for 110VAC with optional 220VAC versions, and compatible with 50Hz or 60Hz systems. Durable construction: PC component housing with DIN rail mounting for compact, secure installation. Electrical protection: Built with PClevel isolation type and 8KV rated transient resistance for improved resilience. Simple integration: Secondary power distribution switch type designed for generator backup systems and automatic conversion. Features Project type: Double power supply automatic conversion switch Component material: PC Switch type: Secondary power distribution Rated current: 100A Rated voltage: 110VAC standard. 220VAC option available. Insulation voltage: 690VAC Rated frequency: 50Hz or 60Hz Electrical grade: PClevel isolation type Surge withstand: 8KV Poles: 4 Switching time: 0.05 second double power transfer Typical applications Home backup generators: Automatically switch household circuits to generator power during outages to protect appliances and electronics. Server rooms and data centers: Provide fast transfer between mains and backup generator to reduce risk of data loss or system interruption. Cold storage, emergency systems, and facility infrastructure: Maintain power for refrigeration, lighting, security, and control systems during utility failures. Installation and use Designed for DIN rail mounting in residential, commercial, and light industrial control panels. Use as part of a generator backup system to automate source selection between utility and generator power. 4 pole configuration supports secure, simultaneous switching of all conductors. Package includes 1 x Automatic Transfer Switch Notes Please allow 1 to 2 cm variance due to manual measurement. Colors shown may vary slightly from actual product because of monitor differences.
