Allen-Bradley H2R-32 Automatic Transfer Switch

The H2R-32 Automatic Transfer Switch is a 2-pole, DIN-rail mounted ATS rated for 32 A at 240 VAC (50/60 Hz) that automatically or manually transfers loads between utility power and a backup source such as a generator or inverter. It is designed for residential, commercial, and industrial electrical systems and is commonly used in residential backup systems, solar installations, UPS setups, industrial control cabinets, and other commercial equipment where uninterrupted power is required. Key specifications include a 690 VAC rated insulation voltage, 8 kV impulse withstand, a transfer time typically ≤ 2 seconds, 35 mm DIN rail mounting, and a flame-retardant thermoplastic housing. Lifecycle ratings are minimum 8,000 mechanical switching cycles and minimum 1,500 electrical switching cycles, with operating modes supporting both utility-to-backup and backup-to-utility transfers.
