Littelfuse's LA100P semiconductor protection fuses are rated 1000V, extending the range of protection for UPS systems, AC and DC drives, reduced voltage motor starters and similar applications where lower l2t and superior reliability are needed. With ratings from 15-1000 amperes, a wide range of high voltage applications can be served. Features: Low l2t minimizes damage to protected components on short circuit. Controlled arc voltage reduces stress to circuit components during fuse clearing. Applications: Protection of UPS systems, AC/DC drives, reduced voltage motor starters and other 1000V or less semiconductor devices.

POWR-SPEED SQB ESR 1500VDC 1XL BOLT 200A

POWR-SPEED SQB SIZE 1XL FLUSH 400A. Littelfuse PSX series 1500 V dc high-speed square bodyfuses are specially designed to protect battery energy storage systems (BESS), photovoltaic inverters, and many of dc applications such as dc common bus systems, larger industrial regenerative drives, rectifiers and, metal processing equipment. The PSX series fuses are extremely fast-acting, offering high-speed performance up to 1500 V dc, ranging from 80 A to 1400 A in the smallest NH XL package sizes. The PSX series is available with multiple mounting terminations including flush-end style, DIN-style and bolted-blade style. Visual blown fuse indication is standard on all fuses and optional micro-switch is available for external indication. PSX series are certified to UL 248-13 and designed to meet EN high-speed semiconductor fuse standard and IEC 60269-7, a new battery protection fuse standard in development.

The 690/700V Protistor® fuse-links provide maximum flexibility in equipment design and ultimate protection for small power conversion equipment. The Protistor® gR have been engineered to provide full range protection to eliminate all overloads and semiconductor fault. Fuses are assembled with pure silver, die-cut elements embedded in solidified sand, which helps control arcing characteristics for a lower I2t and high interrupting rating level. All contact surfaces are silver plated and all hardware is non-magnetic. Each fuse-link can be equipped with a low voltage trip-indicator which can operate a field mountable microswitch. 690 Volts 63 Amps 000 gRB D08V series.
