The device features a single pole double throw configuration

As a differential air pressure switch

Built with a NEMA 2 / UL Type 2 enclosure

This OEM replacement part ensures compliance with local electrical codes while protecting internal circuitry from high-temperature environments typical of gas-fired heat exchangers

The high-grade aluminum construction allows for easy bending and flaring without work-hardening

Warrick 16B1D0R Level Control Refrigerant The device features a singleThe Warrick 16B1D0R Level Control is a rugged, conductive liquid level controller designed for industrial high demand environments. This open circuit board control features a 120 VAC primary supply and is factory configured for direct acting mode, meaning the load relay energizes when the liquid reaches the high probe. Utilizing solid state reliability, the 16B1D0R provides a 10,000 ohm sensitivity rating, making it the standard for general purpose
