Surge Protector SPD model 4P4080KA, Size 3, Color 4080KA 420V AC Description This four pole surge protection device is designed to protect electrical systems and connected equipment from transient overvoltages. Engineered for use in distribution panels and switchgear, the SPD diverts surge current away from sensitive devices and helps maintain continuous operation. Key benefits surge capacity and clear protection levels: nominal discharge current 40KA and maximum discharge current 80KA reduce the risk of damage from large transient events. Defined 8/20 microsecond performance: nominal discharge current (8/20s) 20KA and maximum discharge current (8/20s) 40KA for predictable surge handling in standard surge conditions. Compatible with systems up to 420V AC: suitable for four pole installations in three phase systems with neutral. Compact, panelready size 3: designed to fit standard electrical distribution setups without taking excessive space. option available: unit supports to match site requirements. Simple integration: not a smart device, designed for straightforward electrical installation and maintenance. Technical specifications Type: SPD Model number: 4P4080KA Size: 3 Color: 4080KA 420V AC Is customized: Yes Is smart device: No Nominal discharge current In: 40KA Maximum discharge current Imax: 80KA Nominal discharge current (8/20s) In: 20KA Maximum discharge current (8/20s) Imax: 40KA Input voltage: 420V AC Practical applications Commercial electrical distribution panels: Protect lighting, HVAC, and critical building controls from utility surges and switching transients. Industrial control cabinets: Shield PLCs, motor drives, and sensor networks from lightning induced or switching surges to reduce downtime and equipment replacement. Renewable energy and inverter systems: Provide surge suppression at inverter outputs and distribution points to protect power electronics and batteries. Installation and compatibility notes Four pole configuration suits three phase systems with neutral at up to 420V AC. Designed for panel or switchgear mounting in standard electrical installations. Not a networked or smart device; intended for electrical surge protection only. This SPD model 4P4080KA offers clear, specified surge handling figures and a compact form factor for integration into commercial and industrial electrical systems where reliable transient protection is required.
