UL Power Fuses
Class J – Time Delay – AJT
MAXIMUM CIRCUIT PROTECTION, MINIMAL SIZE Amp-trap 2000® SmartSpot® AJT fuses now provide a visual open fuse indicator. With advanced material technology added to the existing product line 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.
Class L – Time Delay – A4BQ
PUT THE HIGHEST CURRENT-LIMITATION... AT YOUR SERVICE. Amp-trap® 2000 A4BQ fuses are 20% more current limiting than any other Class L fuse on the market. When correctly coordinated, they bring a superior level of protection to service entrance equipment. Downstream circuit components have maximum protection against short circuit let-thru current. A4BQ's built-in, 4-second time delay character (at 500% of rated current) accommodates harmless inrush currents without nuisance opening.
Class CC – Transformer Duty – ATQR
TAKE CONTROL OF FAULT CURRENTS HEADED FOR YOUR CONTROL TRANSFORMER. ATQR small-dimension fuses feature time delay characteristics ideally suited for the high inrush currents of control transformers, solenoids, and similar inductive loads. The newest member of our Amp-trap 2000® family of fuses - ATQR fuses provide superior protection for the branch circuits of electrical distribution systems.
Class CC – Motor Duty – ATDR
THE BEST PROTECTION FOR TODAY'S SMALL MOTORS. Amp-trap 2000® ATDR small-dimension fuses can provide IEC Type 2 "no damage" protection to your facility's increasingly sensitive branch circuit components and small motors - minimizing the risk of fault-related damage. ATDR Class CC fuses deliver the best time delay characteristics in their class with excellent cycling ability for small motor load.
Class RK1 – Time Delay – A2D/A6D
UPGRADE YESTERDAY'S CIRCUITS TO TODAY'S TYPE 2 PROTECTION. The Amp-Trap 2000® SmartSpot® A2D-R and A6D-R fuses feature a visual open fuse indicator and provide IEC Type 2 No Damage protection to main, feeder, and branch circuits for all types of loads. With time-delay characteristics for handling harmless in-rush currents, current-limiting ability and a wide range of ratings (from 1 to 600 Amperes), A2D-R and A6D-R fuses give excellent protection for all your applications.
Class J – Fast Acting – A4J
FOR EXCELLENT CURRENT LIMITING PROTECTION A4J Class J fuses deliver excellent current-limiting protection to a wide variety of applications. Their unique dimensions prevent the substitution of other fuses with lower voltage ratings, interrupting ratings, or current-limiting capability.
Class J – High Speed – HSJ
The High Speed J (HSJ) combines the low I2t of a semiconductor fuse and the branch circuit performance of a Class J UL listed fuse. This fuse was designed for the starting characteristics of solid state motor controllers. The HSJ can provide branch circuit protection per NEC requirements, as well as very low I2t for protection of power semiconductors such as Diodes, SCR’s, GTO’s and SSR’s.
Class CC – General Purpose – ATMR
SMALL FUSE - BIG PROTECTION FOR GENERAL CIRCUITS Amp-trap ATMR fuses, in the Class CC family, are the smallest dimension 600V fuses suitable for branch circuit protection. The ATMR is a popular choice for economical protection of control circuits and control circuit transformers where available short circuit currents exceed 10,000 amperes. ATMR's rejection dimensions prevent substitution by lesser rated fuses.
Class L – 4-Second Time Delay – A4BY
COUNT ON THE HIGH INTERRUPTING RATING OF OUR MOST WIDELY-USED CLASS L FUSE When it comes to protecting service entrance equipment, feeder circuits, and circuit breakers, A4BY fuses have been the industry's favorite. The A4BY is a 100% rated device and may be applied at continuous currents up to its ampere rating. A 4-second minimum time delay at 500% rating allows the A4BY to pass normal current surges and to coordinate with ground fault relays.
Class L – 10-Second Time Delay – A4BT
WHEN YOUR HEAVIER LOADS NEED PROTECTION A4BT FUSES WON'T LET YOU DOWN The high interrupting rating of A4BT current limiting fuses is ideally suited for protecting mains, feeders, and general circuits. The 10-second time delay at 500% of fuse rating is ideal for large motors and other loads with a high inrush. A4BT fuses are suitable for DC applications up to 500VDC.
Class RK1 – High Speed – HSRK
Protect your electrical power wiring and power semiconductors with a single fuse. The new HIGH SPEED RK1 (HSRK) combines semiconductor fuse performance with NEC branch circuit compliance. The fuse was designed with two specific applications in mind: To provide semiconductor fuse performance to solid state drive applications but in the larger RK body sizes that have been typically installed in older systems.
Class RK1 – Fast Acting – A2K/A6K
THESE FAST-ACTING FUSES DELIVER A HIGH DEGREE OF CURRENT LIMITATION WHERE YOU NEED IT MOST Current-limiting A6K fuses provide excellent protection where high available short circuit currents exist. These fast-acting fuses are particularly good for branch/feeder circuits and back-up protection.
Class RK5 – Time Delay – TR/TRS
THE INDUSTRY'S MOST POPULAR FUSE FOR MOTOR CIRCUIT PROTECTION. Tri-Onic® SmartSpot® TR fuses now provide an optional visual open fuse indicator. With advanced material technology added to the existing product line the TR current-limiting time-delay fuses are engineered for overcurrent protection of motors and transformers, service entrance equipment, feeder and branch circuits. Tri-Onic fuse’s proven time-delay characteristic safely handles harmless starting currents and inrush currents associated with today’s motors and transformers.
Class T – A3T/A6T
THESE SMALL DIMENSION FUSES ARE THE RIGHT FIT... FOR A TIGHT FIT Fast acting A3T Class T fuses combine two highly desirable features - high current limitation and a small physical size. Their unique dimensions prevent the substitution of other fuses with lower voltage ratings or current limiting capability. These fuses have glass melamine bodies for superior dimensional stability and catalog numbers stamped into the blades for permanent identification.
Class G – AG
AMP-TRAP AG FUSES FIT RIGHT IN TO A WIDE VARIETY OF INDUSTRIAL APPLICATIONS The Ferraz Shawmut Amp-trap AG fuse series is a complete line of Class G fuses. With time delay (above 5A rating), AG fuses safely fit a wide variety of applications.
