£8.56
The Mersen HP10M32 is a premium gPV photovoltaic fuse link engineered specifically to protect modern solar photovoltaic systems against overloads, ground faults and short circuits. As part of the trusted Mersen HelioProtection® HP10M series, it provides reliable protection for photovoltaic string wiring, combiner boxes, inverter DC inputs and other critical DC circuits operating at up to 1000 V DC.
Rated at 32 A, the HP10M32 is specifically designed for the unique low fault-current conditions encountered in photovoltaic arrays. Its enhanced fuse construction provides excellent resistance to continuous temperature and current cycling, helping maximise system reliability and operational life.
The fuse features ferrule terminals for clip mounting within compatible 10 × 38 mm fuse holders. With a 50 kA DC interrupting rating and compliance with major international photovoltaic standards, it is suitable for residential, commercial, industrial and utility-scale renewable energy installations.
Photovoltaic arrays continue generating DC power whenever exposed to sunlight, making specialist overcurrent protection essential. The HP10M series has been developed specifically to interrupt the relatively low fault currents encountered in photovoltaic installations safely while protecting cables, combiner boxes, inverter inputs and associated equipment.
The HP10M32 is particularly suitable for protecting higher-current photovoltaic strings in commercial rooftop, industrial and utility-scale solar installations where dependable long-term performance is essential.
