Product Advantage
Integrated Open/Close Signal for Remote Monitoring
Equipped with a precision auxiliary signal contact (1NO+1NC), this HRC AC 690V Fuse Holder transmits real-time switch position data to SCADA/PLC systems. Operation teams can remotely verify ON/OFF status, configure fault interlock logic and trigger alarms without on-site inspection, significantly reducing downtime and labor cost for unmanned PV substations and industrial distribution rooms.
High Breaking Capacity with Ceramic Fast-acting Fuse
Mandatorily paired with HMRS12C1 ceramic fast-acting fuse links, this Ceramic 690V 500V Fuse holder achieves 80kA peak withstand current and reliable short-circuit interruption up to AC690V. The high-purity alumina ceramic tube and quartz sand arc-quenching filler ensure rapid current cutoff under fault conditions, protecting downstream inverters, transformers and sensitive control equipment from destructive short-circuit energy.

FAQ
Q1: Can this product be operated under load?
A1: No. This is a fuse switch disconnector for protection and isolation. It must be closed before energizing and must not be operated under load. Load operation will cause fuse blowout and contact damage.
Q2: What is the recommended installation orientation?
A2: The switch must be installed vertically. An insulation pad (300×200×1.5mm) between the base and mounting plate, plus the standard partition plate, is required to ensure reinforced insulation performance.
