Time-Delay Fuse
TR Series - Class RK5
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.

Fast Acting Fuse
ATMR Series - Class CC
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. These fast acting fuses give current
limiting protection to general circuits.
AC:
DC:
600 VAC, 200kA I.R. (1/10 - 30A)
600VDC, 100kA I.R. (1/10 - 30A)
Applications:
 Control Circuits, Lighting, General Loads, Branch Circuit Protection

Time-Delay Fuse
AJT Series - Class J with SmartSpot Indicator
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. AJT’s time
delay characteristics for handling harmless in-rush currents, its current limiting ability (the most current
limiting UL fuse class), and wide range of ratings (from 1 to 600 Amperes) – give excellent protection for
all your applications.

DC:
600 VAC, 200kA I.R. (1 to 600A)
500VDC, 100kA I.R. (1 to 600A)

 Motor Circuits, Mains, Feeders, Branch Circuits, Lighting, Heating & General Loads, Transformers,
Control Panels, Circuit Breaker Back-up, Bus Duct, Load Centers
