What are AJT fuses?
AJT (70-600) EI: With advanced material technology 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.
What is an amp trap fuse?
Opening in less than one-quarter cycle at fault currents up to 300kA, Amp-Trap 2000 fuses minimize the let-thru current that flows downstream. Not only do Amp-Trap 2000 fuses save you from arc flash liability, they minimize the downtime that can diminish your productivity and profits.
What is a Class T fuse?
A Class T fuse is a fast acting, current limiting, fuse that is rated to interrupt a minimum of 200,000 amps. The Type T Fuse is offered in 300 volt AC and 600 volt AC versions. Type T Fuse ampere ratings range from1 to 800 amps. The Bussmann brand name used for Class T fuses is T-Tron,®.
How do I choose a fuse class?
When sizing the fuse, the most common calculation method is to multiply the continous load/feed current of a branch by 1.25, and using the closest rated fuse that is greater than your result.
What is a Class G fuse?
A UL Class G fuse is a 600/480 volts AC current limiting, fuse that is rated to interrupt a minimum of 100,000 amps. Ampere ratings range from ½ amp to 60 amps. The type G fuse meets the NEC, requirements for branch circuit, protection. The type G fuse is listed under UL 248-5, Class G and CSA Certified,.
Which type of fuse is used in houses?
Rewirable or Kit – Kat Type Fuses are a type of Low Voltage (LV) Fuses. They are most commonly used in house wiring, small industries and other small current applications. Rewirable Fuses consists of two main parts: a Fuse Base, which contains the in and out terminal, and a Fuse Carrier, which holds the Fuse Element.
What are midget fuses?
A midget fuse is a non-current limiting, fuse offering supplemental protection,. The midget fuse size dimensions are a diameter of 13/32 inches and a length of 1-1/2 inches. The metric midget fuse size dimensions are a 10mm diameter and a 38mm length. A midget fuse is also known as a 10×38 fuse or a 10x38mm fuse.
What are the characteristics of an AJT fuse?
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.
What’s the mechanical indicator on a Ferraz fuse?
A mechanical Indicator/Microswitch Mount (EI) is available on blade-type (70 to 600A) fuses for visual or remote indication of open fuse condition.
What kind of Fuse do I need for 600vac?
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.
