Model NU6ⅡG Surge Protector 40kA 385V 3P(R) Protect equipment from damaging voltage transients with this threepole surge protector designed for 385V systems. The NU6ⅡG provides a surge current capacity in a compact package for use in distribution panels and control cabinets. Key benefits surge capacity: Rated for 40kA surge current to handle large transient events and reduce the likelihood of equipment damage. Designed for 385V systems: Engineered for threepole power distributions at 385V, providing consistent protection across phases. Threepole configuration: 3P(R) layout supports threephase systems and centralized protection schemes. Compact, panelfriendly form: Built for installation in electrical distribution panels and control enclosures while minimizing space impact. Reliable protection role: Diverts transient overvoltages away from connected equipment to help maintain system continuity and reduce downtime. What it does and why you need it Suppresses transient overvoltages that can damage sensitive electronics, control gear, and power equipment. Provides a capacity discharge path for surge currents, which helps protect downstream devices and extend equipment service life. Suitable where consistent, phasetophase protection is required in threephase electrical installations. Key attributes Model: NU6ⅡG Surge current capacity: 40kA Rated voltage: 385V Poles: 3P(R) threepole configuration Mounting: Designed for electrical panel or distribution board installation Construction: Durable enclosure suitable for electrical distribution environments Typical applications Commercial building distribution boards: Protect lighting, HVAC controls, and building automation equipment from transient voltage events on threephase supply lines. Industrial control panels: Shield PLCs, motor drives, and process control electronics from surges caused by switching events or lightningrelated transients. Renewable energy and inverter systems: Provide surge protection for inverters and balanceofsystem components in threephase installations operating near 385V. Installation notes Install in the main distribution board or selective branch panels according to the system layout and protection coordination plan. Ensure proper connection to the three phases and grounding system for effective operation. Coordinate with upstream and downstream protective devices to achieve the desired level of protection and system continuity. Choose the NU6ⅡG 40kA 385V 3P(R) surge protector when you need a compact, capacity solution for threephase transient suppression in electrical distribution and control applications.
