Why Choose the ABB E9232SPV PV Fuseholder?
The ABB E9232SPV, designated E 92/32s PV, is a 2-pole 32 A photovoltaic fuseholder designed for overcurrent and short-circuit protection in DC solar installations when fitted with suitable fuse links. Identified by ABB order code 2CSM256913R1801, it forms part of the ABB E 90 PV range of modular fuse disconnectors.
Designed for 10.3 × 38 mm PV cylindrical fuse links, the E9232SPV supports operating voltages up to 1000 V DC. Its two-pole configuration enables both conductors of a photovoltaic DC circuit to be accommodated within a compact DIN-rail-mounted device.
The “s” version incorporates a blown-fuse indicator, providing convenient visual identification of fuse status and simplifying fault finding during maintenance. With a DC-20B utilisation category and two-module format, the E9232SPV provides a practical protection and isolation solution for photovoltaic strings, combiner boxes and DC distribution equipment.
