Madison M8800 Liquid Level Float Switch Spst 100 Psi

Product Description

The MADISON M8800 is a full-size liquid level float switch designed for general purpose and acidic condition applications. It uses a single-pole, single-throw (SPST) switching configuration and accepts 1/4-inch threaded connections. The polypropylene body resists corrosive and acidic media, making it suitable for chemical handling, process equipment, and fluid management systems. Rated to 100 psi maximum and 105 degrees F maximum operating temperature, the M8800 operates on 120 volts AC or 240 volts AC. Licensed electricians and industrial maintenance technicians are the primary installers for this type of level control switch.

The M8800 is suited for residential and light commercial fluid systems, as well as general industrial process environments where acidic liquid media is present. Typical installations include sump systems, chemical storage tanks, process vessels, and coolant reservoirs. The 1.5-inch float diameter and 0.6 specific gravity float rating make it appropriate for aqueous and mildly acidic solutions. It is intended for applications where a reliable, corrosion-resistant level switch is required without complex multi-pole logic.

Installation Notes

Installation should be performed by a qualified electrician or industrial maintenance technician in accordance with applicable NEC requirements. Disconnect and lock out all electrical power to the circuit before wiring or removing any existing level switch. Ensure the mounting port thread and fitting material are compatible with the process fluid before installing. Do not exceed the rated 100 psi pressure or 105 degrees F temperature limits during operation.
