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.
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.

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 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.
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 Transformer Protection CS-3 and 9F60/9F62 Series
• Amp-Trap CS-3 and 9F62 series are UL listed for compatibility with UL listed
equipment.
• Ferrule mounting for standard clips and interchangeability with other brands of fuses.
• Current-limiting for superior equipment protection.
• Non-venting for silent operation
• Metal embossed catalog number and manufacturing date for lasting identification.
• Outdoor usage for the 9F62 and 9F60 type EJO.
• Blown-fuse indicator to give positive identification of open fuse:
• Amp-Trap: 2” Barrel 1 lb tripped force – 0.19 Inch
• Amp-Trap: 3” Barrel 2 lb tripped force – 0.50 Inch
• 9F60/9F62: 0.125 lb tripped force – 0.20 Inch
• Accessories – see page E53

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 MOTOR PROTECTION Amp-Trap Bolt-In Series 5.08KV/7.2KV
• The Amp-Trap Bolt-in series are UL Recognized.
• Bolt-in mounting for direct connection to bus or terminals.
• Current-limiting for superior equipment protection.
• Metal embossed catalog number and manufacturing date for lasting identification.
• Blown-fuse indicator to give positive identification of open fuse.
Amp-Trap: 3” Barrel 2 lb tripped force – 0.50 Inch
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.
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.
