The BUSSMANN SPP-7E1200 is a 700 V, high-speed (aR) Semitron square-body fuse for protecting power semiconductors in UPS and converter applications. This Case-7, short-blade E-style variant includes a visual blown-fuse indicator and is designed for clip/holder mounting in common high-current DC link and inverter stacks. Offered here as a reclaimed part from decommissioned equipment—continuity-tested and verified for reuse.
High-speed aR protection:
Engineered for fast interruption to safeguard IGBTs/diodes in rectifiers, inverters, and common-bus rails.
Case-7 Short-Blade, E-style:
Square-body Semitron design with holder-mount knife blades and integrated visual indicator.
Indicator & microswitch-ready:
E-style visual indicator; optional MSW710 microswitch accessory for remote status (sold separately).
700Â V UPS compatibility:
Suited to large-frame UPS and power-electronic systems requiring 700Â VAC aR fuses.
