The 233 is a voltage monitoring relay designed to protect equipment by detecting under- and over-voltage conditions in single-phase AC circuits from 48 to 276VAC. It features DIN rail mounting, red and green LED indicators for fault and normal states, and a SPDT Form C relay output rated at 16 A AC with 4000 VA switching capacity. Adjustable time delay ranges from 0 to 10 seconds to prevent nuisance tripping. The upper voltage setpoint is adjustable between 160 and 276VAC, while the lower setpoint can be configured as 30% to 95% of the upper setting. Hysteresis is factory-set at 2-6% of the set value to prevent relay chattering. The device operates from -20°C to +55°C, meets UL and CE standards, is RoHS compliant, and has an IP40 front-panel protection rating.
