Fusible, Safety Switch, General Duty, 240 V, 2PST

The SQUARE D - D221NRB is a Safety Disconnect Switch, an essential component in industrial electrical systems. This device is designed to interrupt the flow of electricity for safe equipment maintenance and during emergency situations. It falls under the broader category of Electrical Supplies and is intended to allow for quick disconnection of power systems, which may help reduce the risk of electrical accidents during routine operations or unexpected events.

• Amps AC: The switch has a current rating of 30 A, suggesting it's designed for use with this level of electrical current. Overheating or damage could occur if used outside these specifications.
• Compatible Manufacturer Model Number: The model number DRK30 indicates which models this particular product is designed to work with or replace.
• Contact Form: With a 2PST contact form, it determines how many circuits can be controlled and whether they are normally open (NO) or closed (NC).
• Duty: Its general duty classification indicates it is designed for standard applications in various environments. Actual performance may vary based on specific environmental conditions.
• Enclosure Type: NEMA 3R rated enclosure is intended to provide some degree of protection against environmental conditions such as dust, water, corrosion and external ice formation. The actual level of protection will depend on specific usage circumstances.
• Features: Mercury Free & PVC Free attributes are included with consideration towards certain environmental factors. These features do not necessarily guarantee enhanced performance or durability.
• Fusible / Nonfusible: Being fusible means it contains a replaceable fuse designed to respond to electrical overloads. Safe operation depends on proper installation and usage within specified ranges.
• Housing Material & Construction Material : Constructed from galvannealed steel which is typically associated with robustness and resistance to corrosion under certain conditions; outright suitability for specific industrial environments is not guaranteed.
