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

The SQUARE D - DU323RB is a Safety Disconnect Switch, an essential industrial electrical device designed to interrupt the flow of electricity for equipment maintenance and emergency situations. It falls under the broader category of Electrical Supplies and is used by industry professionals to swiftly disconnect power systems, mitigating the risk of electrical accidents during routine operations or unexpected events.

• Amps AC: This switch is rated for a maximum of 100 A, which should be adhered to in order to avoid potential overheating or damage.
• Contact Form: The 3PST contact form indicates how many circuits can be controlled and whether they are normally open (NO) or closed (NC).
• Duty: This switch has a general duty rating, indicating its suitability for standard applications in various environments.
• Electrical Connection: Lugs type connection establishes an efficient electrical circuit within the switch.
• Enclosure Type: The NEMA 3R rating indicates the enclosure's intended resistance against certain environmental conditions like dust, water, corrosion and external ice formation. However, it does not guarantee complete protection under all circumstances.
• Gauge/Conductor: Rated for compatibility with wire sizes ranging from 12 to 1 AWG (Aluminum) and from 14 to 1 AWG (Copper). Adherence to these specifications is recommended for expected performance.
• Horsepower @240V AC: Rated for use with motors up to a maximum power output of30 horsepower at a voltage of240 Volts AC. Exceeding this specification may result in decreased performance or failure."
• Housing Material & Construction Material : Constructed with steel that has been chosen due its known properties related durability and resistance against certain environmental conditions. However, this does not ensure indefinite longevity or total immunity against all possible adverse effects.
