Class RK1 Fuses and Fuse Holders
Significantly more current-limiting than Class RK5, K and H fuses, Mersen’s Class RK1 fuses are ideal for upgrading your existing feeder and branch circuits to arc flash category “0”.
Class RK5 Fuses and Fuse Holders
Tri-Onic RK5 current-limiting time-delay fuses are engineered for overcurrent protection of motors, transformers, service entrance equipment, feeders and branch-circuits
Class L Fuses and Fuse Holders
For heavier loads up to 600A, Mersen's Class L fuses are industry's favorites for protection of inductive loads, service entrance equipment, feeder circuits, and circuit breakers
Class CC Fuses and Fuse Holders
Mersen's Class CC High Interrupting Rating Time Delay and Fast Acting compact fuses, are ideal for protection of smaller motors, control circuits and control transformers up to 30A.
Midget Fuses and Fuse Holders
Mersen's compact midget Time Delay and Fast Acting fuses are an excellent choice for "supplementary" protection of lighting, solenoid, motor and transformer circuits.
PV Fuses and Fuse Holders
Mersen's Helioprotection line of fuses are engineered and designed specifically for the protection of strings and combiner boxes in photovoltaic systems.
Class T Fuses and Fuse Holders
Fast-acting Class T fuses combine high current limitation with a super compact physical size. These small dimension fuses are the right fit…for a tight fit.
Class K5 Fuses and Fuse Holders
Mersen's One-Time general purpose fuses provide low cost protection for feeder and branch-circuits serving lighting, heating, and other non-motor loads. Class K5 fuses will safely interrupt available short-circuit currents up to 50,000 amperes in all ratings up to 600 VAC.
Class G Fuses and Fuse Holders
The Mersen Amp-Trap AG fuse series is a complete line of UL Listed Class G fuses with time-delay (above 5A rating). Class G fuses are made in four physical sizes and provide branch-circuit protection for lighting, heating, and appliance circuits.
Renewable Fuses and Fuse Holders
RF general purpose Class H renewable fuses are suitable for application where available short-circuit currents do not exceed 10,000 amperes
CSA Class H Fuses and Fuse Holders
Mersen Class H fuses are standard fuses. They come in Time Delay version certified as Type “D”, and fast acting certified as Type "P" with 10kA short circuit ratings.
Plug Fuses
Mersen Plug Fuses are for industrial and residential applications. Standard non-time delay fuses are for receptacle and lighting circuits. Standard time delay fuses are for motor loads.
