The Mersen T082403, also identified as FR20GB10C25P, is an ultra-fast cylindrical fuse designed to provide dependable overcurrent protection in demanding industrial electrical systems. Manufactured by Mersen, a recognised specialist in electrical protection, this fuse combines a 25 A rated current with a 1000 V AC rated voltage.
Its gLB operating class provides rapid fault interruption, helping protect sensitive electrical equipment from damaging short-circuit currents and excessive thermal stress. The ultra-fast operating characteristic makes the T082403 particularly suitable for circuits containing power electronic devices and other components that require rapid protection.
The fuse has a cylindrical 20 × 127 mm body and incorporates a striker indicator. This striker can provide a clear indication when the fuse has operated and may be used with compatible fuse holders or auxiliary signalling equipment. Its robust construction supports reliable use in industrial control panels, power conversion equipment, manufacturing machinery and specialist installations, including chemical and salt-processing facilities where effective circuit protection is essential.
Ultra-fast fuses are engineered to interrupt fault currents more rapidly than conventional general-purpose fuse-links. This helps reduce the amount of damaging energy permitted to pass through a circuit during a short circuit or severe overcurrent condition.
The Mersen T082403 is particularly useful where sensitive power components require fast and reliable protection. Its gLB characteristic, 1000 V AC rating and compact cylindrical construction make it suitable for integration into industrial control equipment, power conversion systems and electrical distribution assemblies.
