Surge Protector NXUIIG 100kA 440V 1P+N Overview The NXUIIG 100kA 440V 1P+N surge protector is built to protect singlephase plus neutral electrical systems from transient overvoltage events. Its discharge capacity helps limit surge energy reaching connected equipment, reducing the likelihood of downtime and component damage. Key benefits surge absorption: 100kA nominal discharge capacity to handle large transient events and reduce stress on downstream equipment. Designed for singlephase systems: 1P+N configuration matches common distribution boards and electrical panels up to 440 volts. Compact and panelfriendly: engineered for installation inside distribution panels and electrical enclosures where space is limited. Practical protection for sensitive devices: helps safeguard control electronics, industrial drives, lighting systems, and communication equipment. Simple integration: intended for straightforward inclusion in existing singlephase distribution circuits. Important attributes Model: NXUIIG Type: 1P+N (single pole plus neutral) Rated voltage: 440V Nominal discharge capacity: 100kA Function: transient overvoltage suppression for singlephase distribution systems Form factor: compact module suitable for electrical panels and enclosures Performance and compatibility Compatible with singlephase distribution circuits and equipment that use a neutral conductor. transient handling capability reduces the energy passed to connected loads during surge events. Suitable for commercial, industrial, and residential electrical distribution applications that require robust surge suppression. Use scenarios Industrial control panel: installed at the incoming line of a control cabinet to protect PLCs, motor drives, and sensor networks from lightninginduced or switching transients. Commercial building distribution: placed in a floorlevel or main distribution board to protect HVAC controls, lighting systems, and refrigeration equipment from utility surges. Small manufacturing or workshop: integrated into panel feeding CNC machines, variable frequency drives, and communication routers to reduce equipment downtime and service interruptions. Installation notes Designed for installation inside distribution panels and electrical enclosures by qualified electricians. Ensure the device is installed following local electrical regulations and standard wiring practices for surge protection devices. Technical summary Model: NXUIIG Configuration: 1P+N Voltage rating: 440V Nominal discharge current: 100kA Application: surge suppression for singlephase plus neutral circuits This surge protector is a practical choice when robust transient suppression is needed for singlephase systems rated up to 440 volts. It combines a discharge capacity with a compact form factor for panelmounted electrical protection.
