Ferraz Shawmut Class C fuses have British standard
(BS88) dimensions and are exact replacements for
the British fuses and older HRCII-C fuses. Class C fuses are not dimensionally or electrically interchangeable with other North American fuses.
They feature ceramic bodies and bolt-in mounting.
They are for short-circuit protection only, in motor controllers, for example, where overload protection is provided by an overload relay.

Fusible TRS-R - Class RK5 - Time-Delay
Tri-Onic TRS-R current-limiting time-delay fuses are engineered for overcurrent protection of motors, transformers, service entrance equipment, feeders and branch-circuits. The time-delay characteristics of the TRS-R safely handle harmless starting currents and inrush currents associated with today’s motors and transformers.

Fusible ATM Fast-Acting Midget
Amp-Trap ATM midget fast-acting fuses are rated 600VAC and 600VDC with a 100kA interrupting rating. These ratings give the ATM a wide range of applications not covered by other midget fuses. In addition, ratings of 30/35, 30/40 and 30/50 amperes are offered for specific applications such as capacitor protection.
Fusible ATQR Time-delay/ Class CC
ATQR small-dimension fuses feature time-delay characteristics ideally suited for the high inrush currents of control transformers, solenoids, and similar inductive loads. Mersen’s Amp-Trap 2000 ATQR fuses provide superior protection for the branch circuits of electrical distribution systems.
Fusible ATDR - Class CC - Time-Delay
Amp-Trap 2000 time-delay ATDR small-dimension fuses 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 loads.

Fusible HSJ - Class J - High-Speed
The High Speed Class J (HSJ) combines the low I2t of a semiconductor fuse and the branch-circuit performance of a Class J UL Listed fuse into a single design. The HSJ can provide both branch circuit protection per NEC requirements, as well as very low I2t for protection of power semiconductors such as Diodes, SCRs, GTOs and SSRs.
Fusible A70P Amp-Trap Form 101
A70P Amp-trap Form 101 Semiconductor Protection fuses were developed for higher voltage AC and DC drives, UPS systems, reduced voltage motor starters and similar applications where lower I2t and superior reliability were needed. A70P is a very popular fuse, available in a wide range of ratings.
Fusible TR-R & TRS-R Time delay/ Class RK5
Tri-Onic TRS-R current-limiting time-delay fuses are engineered for overcurrent protection of motors, transformers, service entrance equipment, feeders and branch-circuits. The time-delay characteristics of the TRS-R safely handle harmless starting currents and inrush currents associated with today’s motors and transformers.
Fusible TRM - Midget - Time-Delay
Tri-Onic TRM time-delay midget fuses are rated 250VAC and are offered in 36 ampere ratings from 1/10A to 30A. They have 12 seconds time-delay at 200% rating to provide supplemental protection of small motors, small transformers and other high inrush loads, plus many other 250 volt applications. (Not for Branch Circuit Protection)

Fusible A4BQ - Class L - Time-Delay
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
characteristic (at 500% of rated current) accommodates harmless
inrush currents without nuisance opening.
