Fusible, Safety Switch, General Duty, 240 V, 3PST

The SQUARE D - D321NRB is a Safety Disconnect Switch, an essential electrical device used in various industries. It is designed to interrupt the flow of electricity for safe equipment maintenance and during emergency situations. This switch allows professionals to quickly disconnect power systems, aimed at mitigating potential electrical hazards during routine operations or unexpected events.

• Amps AC: The switch has a current rating of 30 A, indicating its rated capacity to handle this amount of electrical current, which is intended to prevent overheating and damage.
• Contact Form: With a 3PST contact form, it has the capability to manage multiple circuits and indicate their status as either normally open (NO) or closed (NC).
• Duty: Classified as 'General Duty', indicating its designed use in standard applications across various environments.
• Electrical Connection: Uses lugs as connectors to establish an electrical circuit.
• Enclosure Type: Comes with NEMA 3R rated enclosure that is designed with the intention to resist certain environmental conditions like dust, water, corrosion and external ice formation.
• Fusible / Nonfusible: Fusible design aims at providing an extra layer of protection in overcurrent situations by having a fuse that melts when there's an excessive flow of current.
• Gauge/Conductor: Can accommodate wire sizes ranging from 12 to 6 AWG (Aluminum), 14 to 6 AWG (Copper), intended for facilitating good electrical conductivity and performance within specified ranges.
