About This Product

■Summary

The AFD-T4 series is a high-end model class II SPD that has a built-in SPD separator (fuse), is optimized for Japan's power supply system, and has improved reliability and safety.The AFD-T4 series also supports class I. . Built-in SPD separator and screw-up terminal block save space and are easy to install.

■Features

・Save space and reduce wiring work with built-in separator ・Safety plug-in that allows safe SPD plug replacement ・Compatible with JIS C 5381-11 Class I ・Achieved one rank higher overall performance by strengthening ITotal ・Reduced wiring work with screw-up terminal block ・Fault display, alarm contact output (selectable with/without) ・Compliant with public construction work standard specifications and building equipment design standards ・Safety considering Japan's TOV (temporary overvoltage) ・Adopts advanced safety shutoff technology SITS®

■AFD-T223EA with ground terminal for ELCB

AFD-T223EA has two independent grounding terminals so that even if there are two types of grounding terminals in the distribution board, Class D grounding and ELCB grounding, it can be protected by one SPD. It is no longer necessary to install two SPDs or add an SPD between the ground as in the past, making it possible to save space and reduce costs.

■About the applicable circuits AFD-T422SA and AFD-T422S

Single-phase 3-wire 100/200V and 3-phase 3-wire 200V can be used if the N phase (grounding phase) is clear. However, when installing a class I SPD (AFD-S series) in the power supply area, please use AFD-T423S (A) or AFD-T223S (A).
