Why Choose the ABB E9250 Fuse Holder?
The ABB E9250, type designation E 92/50, is a robust two-pole cylindrical fuse holder and fuse disconnector designed for circuit protection and isolation in industrial and commercial electrical installations. As part of the ABB E 90/50 fuse disconnector series, it accommodates standard 14 × 51 mm cylindrical fuse links and provides a compact DIN-rail-mounted solution for electrical distribution and control panels.
The E 92/50 combines secure fuse mounting with disconnection functionality, allowing circuits to be isolated for maintenance while correctly selected fuse links provide protection against overloads and short circuits. Its two-pole configuration protects both poles simultaneously, while the padlockable design allows the device to be secured in the open position to support safer maintenance procedures.
With a rated operational current of 50 A and rated operational voltage of 690 V AC, the E9250 is designed for demanding low-voltage electrical systems. Its 14 × 51 mm fuse format, AC-20B utilisation category and modular DIN-rail construction make it suitable for industrial circuit protection where dependable fuse isolation is required.
