• Fail-Safe Circuitry (20HPGMT05FR only): load sharing permits either feed to power all loads if the other feed fails. • Noise Filter Circuitry (20HPGMT05BNR and 20HPGMT05BNR-24) Telect’s High-Power GMT Series Fuse Panels use discrete, not modular, GMT fuse holders, to limit heat buildup when using 15A and 20A GMT fuses.
