- Control transformers
- Solenoids
- Inductive loads
- Lighting, heating & general-purpose loads Note: See motor fuse applications tables for more information APPROVALS:
- UL listed to standard 248-4 File E2137
- DC listed to UL standard 248
- CSA certified to standard C22.2 No. 248.4 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 ATQR fuses provide superior protection for the branch circuits of electrical distribution systems. FEATURES/BENEFITS:
- Time-delay for control transformer inrush loads without nuisance opening
- Highly current-limiting for low peak let-thru current
- Rejection-style design prevents replacement errors (when used with recommended fuse blocks)
- High visibility orange label ensures instant brand recognition, and simplifies replacement
- Metal-embossed date and catalog number for traceability and lasting identification
- Fiberglass body provides dimensional stability in harsh industrial settings
- High-grade silica filler ensures fast arc quenching and high current limitation HIGHLIGHTS:
- Time-delay
- Best choice for small transformer protection
- Current-limiting ATQR Time Delay/Class CC UL/CSA LISTED POWER FUSES TAKE CONTROL OF FAULT CURRENTS HEADED FOR YOUR CONTROL TRANSFORMER
