Schneider Electric NSB FP221R Disconnect Switch

Schneider Electric's Square D FP221R fusible disconnect switch (NSB FP221R) is a two-pole, 30-amp pull-out disconnect designed for 240-volt air-conditioning equipment. Housed in a weather-resistant metallic enclosure with a NEMA 3R rating, it is intended for outdoor installations such as condensers, heat pumps, and rooftop AC units. This is a fusible disconnect; fuses are not included and must be supplied separately. The pull-out fuse carriers provide accessible, serviceable protection in a compact package, making FP221R suitable as a dedicated service disconnect or as a control point in outdoor HVAC circuits. The device is designed to interrupt power cleanly and safely to outdoor loads, with the familiar Square D/Schneider Electric approach to robust electrical protection. Typical applications include outdoor HVAC equipment where code-required isolation is installed adjacent to the unit, delivering reliable 240 V switching and circuit protection in a compact, pull-out design.
