It can disconnect both poles of a circuit simultaneously or switch a load between two different power sources — commonly used in generator changeover panels, motor control boards, and industrial power distribution systems.\u003c\/p\u003e\n\u003ch4\u003eQ: Which current rating should I choose — 32A, 63A, or 100A?\u003c\/h4\u003e\n\u003cp\u003eA: Choose a current rating that meets or exceeds the maximum load current of your circuit. For light-duty applications such as small workshop equipment, 32A is suitable. For medium-duty loads like larger motors or sub-panels, 63A is recommended. For heavy-duty industrial or high-current applications, select the 100A option. Always consult a qualified electrician if you are unsure.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this switch suitable for both AC and DC applications?\u003c\/h4\u003e\n\u003cp\u003eA: This switch is rated for AC 220V. While knife disconnect switches can sometimes be used in DC circuits at lower voltages, this product is specified for AC use. Always verify the voltage and current requirements of your application before installation.\u003c\/p\u003e\n\u003ch4\u003eQ: What does \"double throw\" mean on this switch?\u003c\/h4\u003e\n\u003cp\u003eA: \"Double throw\" means the switch has two output positions — it can connect the input to one of two separate circuits. Combined with \"double pole,\" it simultaneously controls two conductors, making it highly effective for source-transfer and changeover wiring applications.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is a DPDT knife disconnect switch used for?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"A DPDT (Double Pole Double Throw) knife disconnect switch is used to manually isolate or transfer electrical circuits.
