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 ATQ Time- Delay Migdet
Amp-Trap ATQ midget time-delay fuses are rated 500VAC with 42 ampere ratings from 1/10 to 30A. They are an excellent choice for supplemental protection of circuits where the available short circuit current does not exceed 10,000A. (Not for Branch Circuit Protection)

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 A70QS Amp-Trap Form 101
A70QS Amp-trap Semiconductor Protection fuses were developed in response to the need for improved overall performance of 700 volt semiconductor fuses for new equipment requirements. A70QS fuses have lower I²t for better protection, longer life when subjected to cyclic loading, plus lower watts loss. A70QS is the best choice to protect dynamic solid state equipment such as motor drives, UPS, etc.

-With trip indicator
• Model complying with DIN 43620 (00C)
-Standard with or without blown fuse indication
-With trip indicator
OT, OTN and OTS fuses are not rejection fuses -care should be taken to ensure that replacement fuses do not have lower interrupting ratings than
original fuses.
OTN 15 through 60 satisfy the Canadian electrical code requirement for Type «P» low melting-point, non-time delay fuses.

Multi-meter fuses 10x35/10x38 FSM 1000V
Mersen has developed a true 1000VAC/DC fuse designed to protect both analog and digital multi-meters. These fuses cover all the industry’s multi-meter requirements in three easy to use amperage ratings. Good for 1000 volts AC and DC, the FSM line of Ferraz Shawmut fuses are designed for the power electronics metering and controls market.
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 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.
