The Schurter 3403.0289.11 is a surface mount fuse from the UMT-H series, rated for 30A continuous current at 250VAC and 72VDC. It offers a slow blow (time-lag T) response characteristic, making it suitable for applications with inrush currents. The fuse has a breaking capacity of 100A at 250VAC and 500A at 72VDC, with a melting I²t of 1650 A²s. Its ceramic housing and Ni/Sn-plated copper alloy terminals provide durability and reliable performance over an operating temperature range of -55°C to 125°C.
The fuse is designed for primary protection on SMD PCBs and is impermeable to potting compounds, enabling use in intrinsically safe applications according to ATEx and IECEx requirements. It is suitable for pulse-shaped continuous currents and is commonly used in sensors, power supplies, illumination, and battery protection circuits.
Packaged in a 2-SMD square end block case, this fuse supports reflow soldering with a solderability rating of 245°C / 3 sec and resistance to soldering heat of 260°C / 10 sec. It carries approvals from CQC, cURus, and VDE, and is compliant with RoHS and REACH standards.
