Full-range gR fuse-links according to IEC 60269-4 and VDE 636-23, in square-body size 70, rated for 350–600 V DC and 50–350 A. The gR class interrupts both short circuits and overloads while maintaining low I²t to protect diodes, thyristors and IGBT modules. The fuse-links carry UL/CSA recognition (file E76491).
The family is available with several connection styles; TF versions weigh 0.34 kg and ESF versions 0.4 kg - for example D70GB35V350ESF (350 V, 350 A, 47 W losses) and D70GB55V250ESF (550 V, 250 A). ESF versions work with SF 70 holders in traction design, enabling replaceable fuse assemblies in rail-vehicle equipment.
Application according to the datasheet: protection of inverters, drives, UPS systems and similar equipment up to 600 V - in rolling stock, respectively, converters and onboard equipment supplied from low-voltage circuits.
