JLLN150 - 150Amp Fuse

JLLN150 - 150Amp Fuse

When you need high‑current protection in a compact footprint, the JLLN150 is built to deliver. This 150 amp continuous fuse supports up to 300 VAC and 125 VDC, making it ideal for safeguarding critical systems such as motor drives, UPS units and tight panelboard installations. Its current‑limiting design is engineered to cut off fault currents — up to 200 000 A at 300 VAC — in the blink of an eye, reducing damage to wiring, equipment and downstream components. With a knife‑blade/bolt‑in mounting style in a Class T form factor that’s less than one‑third the size of many comparable fuses, the JLLN150 supports space‑efficient installations while maintaining high interrupting capability. Whether you’re optimizing industrial motor control centers, backup power systems or compact distribution panels, this fuse offers the reliable protection you need with smart installation flexibility.

Key Features and Benefits

• Fast‑Acting Over‑current Protection: Responds quickly to surges and short‑circuit events to help safeguard sensitive or expensive equipment.
• Compact Class T Form‑Factor: Takes up significantly less space than traditional Class R fuses, helping maximize panel real‑estate.
• Knife‑Blade/Bolt‑In Mounting: Ensures stable, vibration‑resistant connections in demanding industrial or commercial setups.
• Current‑Limiting Technology: Limits energy delivered during fault conditions to help reduce stress on equipment and avoid collateral damage.
• High Interrupting Rating: Handles very high fault levels (up to 200 kA AC) while maintaining safety and reliability.
