MERSEN (FERRAZ SHAWMUT)

Mersen fuses - Hot Spot fusesMersen was founded several years ago by combining the domestic company Gould Shawmut with the lead European fuse company Carbone Lorraine Ferraz. Mersen fuses now has the best international array of fuses with the technical superiority of the American leader.

 

Mersen Fuses Offering No-Damage Circuit Protection

Mersen arc flash fuses are type-2 no-damage circuit protection and are available in four classes: Class CC, Class J, Class RK1, and Class L. Opening in less than quarter cycles under short circuit conditions, Mersen fuses limit enough current to prevent down time and arc flash damage. Their current-limiting ability is among industries highest allowed levels for motor starting and transformer in rush current without nuisance opening. Smart Spot open fuse indicator was added to the line. When the Mersen fuse opens, Smart Spot immediately surges it and turns from silver to red. The Spot remains red to facilitate proper capable out.

 

Mersen fuses come in a full line of midget, miniature and PC mount fuses. Mersen’s complete power fuse offering covers a wide range of applications and a complete range of circuit protectors. AMP-TRAP power fuses, TRI-ONIC time delay and the ONE-TIME fuse line Class J: AJT, A4J, HSJ; Class L: A4BQ, A4BY, A4BT; Class CC: ATDR, ATQR, ATMR; Class RK1: A2K, A6K, A2D, A6D; Class T: A3T, A6T; Class RK5: TR, TRS; Class K: OT, OTS.

2-1/4A 600V TD J
Amp-Trap 2000® AJT fuses provide non-indication as well as a SmartSpot visual open fuse indicator. With advanced material technology the AJT fuse provides IEC Type 2 No Damage protection to main, feeder, and branch circuits, for all types of loads — yet, they require only half the mounting space needed for 600VAC Class RK fuses. AJT’s time-delay characteristics are ideal for handling typical motor and transformer inrush currents, while also providing superior current-limiting ability.
  • Non-indicating or solid state SmartSpot visual blown fuse indicator
  • Time-delay for motor starting and transformer inrush
  • 300kA interrupting rating - self-certified, UL witnessed tests
  • Extremely current-limiting for low peak let-thru current
  • Most current-limiting UL class fuse
  • Recommended for Arc Flash energy reduction
  • Small footprint requires less mounting space and allows smaller, more economical fuse blocks
  • Easy 2-to-1 selectivity for prevention of nuisance shutdowns
  • Unique Class J dimensions prevent replacement errors
  • High-visibility orange label gives instant brand recognition
  • Metal-embossed date and catalog number for traceability and lasting identification
  • Fiberglass body provides dimensional stability in harsh industrial settings
  • High-grade silica filler ensures fast arc quenching
  • Optional EI indicator/switch mount for AJT70 to 600 open fuse indication.

Applications

  • Motor circuits
  • Mains
  • Feeders
  • Branch circuits
  • Lighting, heating & general loads
  • Transformers
  • Control panels
  • Circuit breaker back-up
  • Bus duct
  • Load centers
