DITEK D300M-4803D 300KA Phase Modular Surge Protective Device, 480VAC

Protect facility power distribution and connected systems with the DITEK D300M-4803D surge protection module. Designed for industrial and commercial sites, this surge protective device delivers high-energy defense (300,000 A per phase) for 480VAC three-phase delta panels, preserving uptime for security, surveillance, monitoring and network gear. The ZEUS D300M series combines a replaceable SPD module and integral disconnect to simplify maintenance and reduce mean time to repair.

Operators get clear, actionable status with visual LED end-of-life and phase-loss indicators, an audible alarm with silence function, and Form C dry contacts for integration into building management and remote monitoring systems. EMI/RFI filtering also helps prevent nuisance issues on sensitive IT and communications equipment. UL1449 listed and backed by a 10-year limited warranty, the D300M-4803D meets bid/spec requirements for facility-wide protection. Ideal for electrical rooms, data closets, security control centers, and industrial panels—specify this DITEK surge protector to safeguard critical infrastructure and ensure continuous operation.
