The 840-DS1 from Allen Bradley is identified as a float switch, specifically engineered for electromechanical operation. The switch is safeguarded within a NEMA Type 1 enclosure, making it suitable for indoor applications where liquid management is required.

Its main functionality revolves around sump operations, ensuring that it is optimized for environments where precise liquid level control is necessary. An advantage of this model is its low operating force, which allows for sensitive response to fluid level changes.

The 840-DS1 supports multiple voltage scenarios. For single-phase at 115 Volts AC, it is rated for a maximum of 1.5 horsepower, while at 230 Volts AC, the rating increases to 2 horsepower. In contrast, for two or three-phase setups at 115 Volts AC, the maximum power capacity also sits at 2 horsepower. Furthermore, it can handle up to 3 horsepower at 230, 460, or 575 Volts AC in multi-phase applications. For lower voltage DC applications, the switch can manage up to 0.25 horsepower at 32 Volts DC.

This float switch is equipped with two normally open contacts, designed to enhance its operational efficiency. The combination of these specifications ensures that the Allen Bradley 840-DS1 float switch provides reliable performance for a variety of sump-related tasks.
