HSJ

HIGH SPEED/CLASS J Protect your wiring and power semiconductors with a single fuse. The new High Speed J (HSJ) combines the low I2t of a semiconductor fuse and the branch circuit performance of a Class J UL listed fuse. This fuse was designed for the starting characteristics of solid state motor controllers. The HSJ can provide branch circuit protection per NEC requirements, as well as very low I2t for protection of power semiconductors such as Diodes, SCR’s, GTO’s and SSR’s.

Features/Benefits ➤ Optimized over-load capability for withstanding elevated levels of current during electronic motor controller starts ➤ Low I2t (low thermal energy) ➤ Excellent Cycling Ability for frequent starts/stops without nuisance opening

A4BY

CLASS l count on the high interrupting rating of our most widely-used class L fuse When it comes to protecting service entrance equipment, feeder circuits, and circuit breakers, A4BY fuses have been the industry’s favorite. The A4BY is a 100% rated device and may be applied at continuous currents up to its ampere rating. A 4-second minimum time delay at 500% rating allows the A4BY to pass normal current surges and to coordinate with ground fault relays.

Features/Benefits ➤ Unique dimensions prevent replacement by other fuse classes ➤ Blade stamped catalog numbers for permanent identification ➤ Glass melamine body and plated terminals provide superior reliability in harsh environments

HSRK

high speed/class rk1 High speed rk1 (HSRK) Protect your electrical power wiring and power semiconductors with a single fuse. The new HIGH SPEED RK1 (HSRK) combines semiconductor fuse performance with NEC branch circuit compliance. The fuse was designed with two specific applications in mind: 1. To provide semiconductor fuse performance to solid state drive applications but in the larger RK body sizes that have been typically installed in older systems. 2. To provide industrial power applications with the most current limiting fuse available, which in turn provides the best arc flash mitigation available to power systems using the larger RK size fuses.

Features/Benefits

ATMR

class CC SMALL FUSE - BIG PROTECTION FOR GENERAL CIRCUITS Amp-trap® ATMR fuses, in the Class CC family, are the smallest dimension 600VAC/DC 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.

Features/Benefits ➤ Rejection style design prevents replacement errors when used with recommended fuse blocks ➤ Versatile design for individual component and branch circuit protection

HIGHLIGHTS:

Applications:

➤ Fast Acting ➤ Very Current-Limiting

➤ Control Circuits ➤ Lighting ➤ General Loads ➤ Branch Circuit Protection

Ratings ➤ AC: 1/10 to 30A 600VAC, 200kA I.R. ➤ DC: 1/10 to 30A 600VDC, 100kA I.R.

OT/OTN/OTS

class K-5 for versatility and economy, these general purpose fuses are hard to beat OT, OTN and OTS general purpose fuses provide low cost protection for feeder and branch circuits serving lighting, heating, and other non-motor loads. OT, OTN and OTS fuses will safely interrupt available short circuit currents up to 50,000 amperes in all ratings.

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. Features/Benefits ➤ Easy to read imprint label for quick recognition and replacement ➤ Low cost for high protection value

HIGHLIGHTS:

Applications:
