SQUARE D HU361DX Safety Switch, 600VAC/DC, 3 Position, 30A

Square D HU361DX safety switch is used in industrial and commercial settings to provide a disconnect means for machinery and equipment. It ensures safe maintenance, repair and protection against electrical hazards. This safety switch has a 30A rating and single throw functionality, safeguarded by NEMA 1 protection. It comes with a fusible disconnect switch that includes a 3-pole, 600VAC capability, along with a robust 10kA short circuit rating. Suitable for surface mounting, this safety switch facilitates secure electrical connections via lugs that accept wires ranging from 14 to 6 AWG copper to 12 to 6 AWG aluminium.

Working Mechanism:

• Positioned in the on state, it permits current to circulate within the circuit.
• For maintenance or emergencies, the switch is activated to the off position.
• This manoeuvre severs the electrical power flow, heightening safety levels.
• Once the matter is resolved, the switch can be reverted to the on position.
• Such reinstatement of the switch recommences power transmission in the circuit.

Frequently Asked Questions:

Q. How do I detect a faulty safety switch?

A.

• Observe if the safety switch consistently trips or fails to reset.
• Test the switch by toggling it on and off; lack of response may signal a fault.
• Inspect for physical damage, burns, or signs of wear on the switch.
• Use a voltage tester to verify power flow through the switch when activated.
• Notice if the switch feels loose or exhibits erratic behavior.
• Consider consulting an electrician for expert assessment and repair.

Q. What factors should I consider while choosing a safety switch?

A.

• Determine the appropriate amperage rating for your application.
• Choose between a fusible or non-fusible safety switch based on your needs.
• Select the suitable voltage and phase configuration for your electrical system.
• Consider the environment and location for proper NEMA or IP rating.
• Evaluate the switch's short-circuit current rating (SCCR) for safety.
• Decide on the mounting type: surface or enclosed.

Q. Does Raptor Supplies offer other safety switches having lower voltage ratings?

A. Customers looking for Square D safety switches having lower voltage ratings can look for 240VAC / DC safety switches having a voltage rating of 240VAC.
