The key difference is the maximum current rating: the 63A model handles loads up to 63 amps, while the 100A model supports loads up to 100 amps. Choose based on the total rated current of the circuit you need to protect.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I adjust the trip voltage thresholds myself?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The protector features user-configurable thresholds. You can set the overvoltage trip point anywhere between 130 V and 300 V, and the undervoltage trip point between 80 V and 210 V, directly on the unit. The auto-reconnect delay is also adjustable from 1 second up to 600 seconds.\u003c\/p\u003e\n\u003ch4\u003eQ: Does this protector work with standard DIN rail panels?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The unit is designed specifically for standard DIN rail mounting, making installation quick and straightforward in any residential, commercial, or industrial distribution panel that uses DIN rail.\u003c\/p\u003e\n\u003ch4\u003eQ: Will the protector reconnect automatically after a fault clears?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. Once voltage on the line returns to within your configured safe range, the protector waits for the duration of the user-set delay (1 s–600 s) and then automatically closes the circuit to restore power supply — no manual reset required.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is the difference between the 63A and 100A versions of this voltage protector?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Both models offer the same overvoltage, undervoltage, overcurrent, and phase-imbalance protection with an identical LCD display and DIN rail form factor.
