600V 250A CLASS J HS FUSE

600V 250A CLASS J HS FUSE

Item #: HSJ250

Supplier Part #: HSJ250
Brand: Mersen

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.

Branch circuits; Electronic motor controllers; Soft-starters; CSA certified to standard C22.2 no. 248.8; Control panels; Phase controllers; Drives; Solid state relays; UL listed to standard 248-8 File E2137; Optimized over-load capability for withstanding elevated levels of current during electronic motor controller starts; Low I2t (low thermal energy); DC listed to UL 248; Excellent cycling ability for frequent starts/stops without nuisance opening

250V 110A 7 1/8x1 9/10 K5FUSE

Item #: OT110

Supplier Part #: OT110
Brand: Mersen

One-Time OT and OTN general purpose fuses provide low cost protection for feeder and branch-circuits serving lighting, heating, and other non-motor loads. OT and OTN fuses will safely interrupt available short-circuit currents up to 50,000 amperes in all ratings. OT and OTN fuses are not rejection fuses and care should be taken to ensure that replacement fuses do not have lower interrupting ratings than original fuses. OTN(15-60) satisfy the Canadian electrical code requirement for Type P low melting-point, non-time-delay fuses.

Easy to read imprint label for quick recognition and replacement; Residential and small commercial installations; UL Listed to Standard 248-9 File E2137; Feeders; Self-certified for DC per UL248; Low cost for high protection value; Resistive heating; CSA Certified to Standard C22.2 No. 248.9 (The Canadian Electrical Code requires these fuses in ratings 15 through 60A to be of the low melting point design; use OTN 15-60.); Branch circuits
