Why Choose the ABB E9132PV E 91/32 PV Fuseholder?
The ABB E9132PV (E 91/32 PV) is a dedicated single-pole photovoltaic fuse disconnector designed for overcurrent and short-circuit protection in DC solar installations. Part of the ABB E 90 PV range, it accepts 10.3 × 38 mm cylindrical PV fuse links and provides a rated current of 32 A.
Engineered specifically for photovoltaic applications, the E 91/32 PV is rated for operation at up to 1000 V DC with a DC-20B utilisation category. Its compact single-module design provides a space-efficient method of integrating replaceable fuse protection and circuit disconnection into PV combiner boxes, distribution boards and DC protection assemblies.
The E 90 PV design incorporates a 90° opening handle for convenient horizontal fuse insertion, terminals accepting conductors up to 25 mm², and ventilation features that support heat dissipation. The holder can also be padlocked in the open position and sealed when closed to support safe maintenance and prevent unauthorised operation.

Dedicated DC Fuse Protection for Photovoltaic Systems
Photovoltaic strings can generate significant DC fault currents, making correctly selected DC-rated protective devices essential. The ABB E 91/32 PV is specifically engineered for photovoltaic circuits operating at up to 1000 V DC and accepts 10.3 × 38 mm PV fuse links selected according to the current and protection requirements of the installation.
Its compact single-module construction helps minimise panel space, while the 90° opening mechanism simplifies fuse replacement. Padlocking in the open position supports safe maintenance isolation, and sealing in the closed position helps prevent unauthorised access, making the E 91/32 PV suitable for professional solar DC protection assemblies.
Typical Applications
- Photovoltaic string protection.
- Solar PV combiner boxes.
- DC distribution and protection panels.
- Photovoltaic inverter input protection.
- Commercial and industrial solar installations.
