ATQR2-1/4 – Mersen | CC TD FUSE 600V 2-1/4A

Description

The Mersen 600V 2-1/4A CC Time-Delay Fuse (ATQR2-1/4) is designed to handle the high inrush currents associated with control transformers, solenoids, and other inductive loads. It offers reliable protection for branch circuits within electrical distribution systems.

Key Features

• Time-Delay Functionality: Allows for the management of control transformer inrush currents without causing nuisance openings.
• Current-Limiting: Provides excellent protection by limiting the peak let-thru current.
• Rejection-Style Design: Prevents incorrect replacements by fitting exclusively with compatible fuse blocks.
• High-Visibility Label: Features an orange label for easy identification and simplified replacement.
• Durable Construction: Fiberglass body ensures stability and durability in harsh industrial conditions. Includes a metal-embossed date and catalog number for traceability.
• Efficient Arc Quenching: High-grade silica filler ensures rapid arc quenching and high current limitation.

Specifications

• Voltage Rating: 600V AC
• Current Rating: 2-1/4A
