Why Choose the Mersen USGM1IHEL UltraSafe™ Photovoltaic Fuse Holder?

The Mersen USGM1IHEL is a compact, finger-safe single-pole photovoltaic fuse holder designed for high-voltage DC solar protection systems. Part of the advanced Mersen UltraSafe™ USGM series, it combines secure 10 × 38 mm fuse mounting, an integrated visual indicator and screwless spring-pressure terminals in a space-saving DIN rail format.

This fuse holder incorporates proven CAGE CLAMP® terminal technology, allowing conductors to be connected without conventional terminal screws. The spring-pressure connection maintains consistent contact force through vibration, temperature cycling and long-term operation, helping reduce installation time and ongoing maintenance requirements.

Rated at 32 A and up to 1000 V DC, the USGM1IHEL is suitable for compatible midget photovoltaic fuse-links used in combiner boxes, inverter input circuits and DC distribution panels. Its integrated LED blown-fuse indicator assists fault identification, while the IP20 finger-safe housing improves protection during inspection and fuse replacement.

Safe and Efficient Photovoltaic Fuse Installation

Photovoltaic fuse holders provide a secure mounting and connection point for fuse-links protecting solar strings, combiner circuits and inverter inputs. A correctly specified holder must withstand high DC voltages, repeated thermal cycling and the operating conditions found within renewable energy control equipment.

The Mersen USGM1IHEL combines finger-safe fuse access, spring-pressure wiring and visual fuse-status indication in one compact device. This allows panel builders and solar installers to simplify wiring, identify failed fuse-links more quickly and conserve valuable DIN rail space within photovoltaic control panels.

Typical Applications

Photovoltaic string combiner boxes.
Solar inverter DC input protection.
Commercial rooftop photovoltaic systems.
Utility-scale solar installations.
High-voltage DC distribution panels.
Renewable energy control cabinets.
