**MEGA[®] SN SERIES** SEALED WATER-RESISTANT FUSE HOLDER ## **Specifications** **==> picture [23 x 6] intentionally omitted <==** **----- Start of picture text -----**<br> 880014<br>**----- End of picture text -----**<br> ## **Description** The Littelfuse MEGA[®] SN Series 70V Bolt-Down Sealed Water-Resistant Fuse Holder is an ideal solution for highcurrent, in-line, main or branch circuit protection in harsh or hazardous environments. AssureLatch™ sealed positive latching technology is used to ensure a water-resistant and ignition protected fuse holder design. A waterproof fuse compartment inside the fuse holder assembly protects against fuse corrosion. The base features an M6 mounting hole and an M6 mounting slot for secure attachment, and it boasts a footprint that matches similar fuse holders, which makes switching from an unsealed to sealed fuse holder simple. A built-in tether between the fuse holder base and cover keeps the components together during servicing. The MEGA[®] SN Series sealed fuse holder is available with and without pre-loaded MEGA[®] high-current bolt-down fuses. ## **Applications** - High-Amperage, In-Line, Main or Branch Circuit Protection in Harsh or Hazardous Environments ## **Web Resources** Download 2D print, installation guide and technical resources at: **littelfuse.com/mega-sn** **Current Rating Max:** 500A **Fuse Type:** MEGA **Humidity:** 0-95% RH **Recommended Torque Recommended Input Terminal** 20Nm (15Lb-ft) ±20%, **Stud Torque:** MAX.

Founded in 1927 and headquartered in Chicago, Illinois, Littelfuse is a premier global manufacturer of circuit protection, power control, and sensing technologies. Widely recognized for pioneering the first small, fast-acting protective fuse, the company has grown into an industry leader whose highly reliable components are essential to modern industrial, transportation, and consumer electronics applications worldwide. At the core of the Littelfuse portfolio is an expansive and industry-leading range of circuit protection solutions. This encompasses a massive selection of traditional fuses, fuse holders, and resettable PTC thermistor fuses designed to safely interrupt overcurrent conditions. To defend against electrical overstress, Littelfuse also provides advanced transient voltage suppression (TVS) technologies, including thousands of specialized TVS diodes, TVS varistors, and gas discharge tubes (GDTs) that ensure robust defense against voltage spikes and environmental hazards. Beyond its foundational protection components, Littelfuse manufactures a diverse array of discrete semiconductors, sensors, and switching devices. Engineers rely on their high-performance thyristors, including TRIACs and SCRs, alongside power-efficient Schottky diodes and MOSFETs for demanding power control applications. Complemented by precision proximity sensors and highly reliable reed and solid-state relays, Littelfuse delivers the critical building blocks required for secure, efficient, and complete system design.
