Why Choose the Mersen J097298 Four-Pole Fuse Holder?
The Mersen J097298 is a robust four-pole fuse holder assembly designed for use with 20 × 127 mm cylindrical semiconductor fuse-links. Also identified by the catalogue reference PS204PREBSMCPS, it provides secure fuse mounting and dependable circuit protection for high-voltage industrial power systems.
Part of the Mersen PS 20 × 127 range, the J097298 is rated for systems up to 1500 V and currents up to 125 A. Its four-pole configuration enables multiple conductors or phases to be protected within one coordinated assembly, making it suitable for industrial converters, traction equipment, renewable energy systems and power distribution cabinets.
The fuse holder incorporates open-fuse indicating microswitches for remote fault signalling when compatible striker-operated fuse-links are installed. Its fibreglass-reinforced polyester construction provides excellent mechanical strength and resistance to demanding or corrosive industrial environments.
