£8.23
The Mersen HP10M5 is a compact, high-performance gPV photovoltaic fuse link engineered specifically to protect modern solar photovoltaic systems against overloads, line faults and ground faults. As part of the trusted Mersen HelioProtection® HP10M series, it provides dependable protection for photovoltaic strings, combiner boxes, inverter DC inputs and battery charging systems operating at up to 1000 V DC.
Rated at 5 A, the HP10M5 has been 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 extend the operational life of solar installations.
Featuring ferrule terminals for clip mounting, the HP10M5 installs easily into compatible 10 × 38 mm photovoltaic fuse holders. It is suitable for residential, commercial and utility-scale renewable energy installations requiring reliable full-range gPV protection.
Photovoltaic arrays continue generating electrical power whenever exposed to sunlight, making specialist DC overcurrent protection essential. The HP10M series has been specifically developed to interrupt the relatively low fault currents encountered in photovoltaic installations safely while protecting cables, combiner boxes, inverter inputs and associated equipment.
The HP10M5 is ideal for protecting low-current photovoltaic strings and other critical DC circuits in residential, commercial and industrial renewable energy systems. Its durable construction provides excellent performance under repeated thermal cycling and continuous outdoor operation.
