Mersen ATMR3 Class CC Amp-Trap Fast Acting Fuses, 600V AC, 3A

Protect critical control and security systems with the Mersen Electrical Power ATMR3 — a Class CC, fast-acting amp-trap fuse engineered for compact, reliable overcurrent protection. This 3A, 600V AC fuse provides current-limiting interruption to reduce destructive fault energy and protect control circuit transformers, monitoring modules and surveillance equipment from damage. The ATMR series combines a small footprint with rejection-style dimensions to prevent misapplication and ensure code-compliant replacement only in compatible fuse blocks. Designed for branch-circuit and individual component protection where available short-circuit currents exceed 10,000 A, the ATMR3 helps reduce repair costs and downtime by quickly isolating faults before they propagate. For electrical contractors and system integrators working on security, surveillance and industrial control installations, the Mersen ATMR3 delivers predictable performance, simplified maintenance and enhanced system uptime. Specify the ATMR3 for compact, dependable protection in control panels, surveillance racks and monitoring systems — order now to secure your equipment and maintain continuous operation.

• Space-saving Class CC size: compact 600V form factor saves panel space and simplifies rack and enclosure layouts.
• Fast-acting, current-limiting protection: quickly interrupt faults to minimize damage to transformers, control modules and surveillance equipment.
• Rejection-style design: prevents incorrect substitutions for consistent safety and code-compliant installations.
• Reliable protection for control and branch circuits: ideal for control transformers, monitoring equipment and security/surveillance panels.
• Reduces downtime and maintenance: limits fault energy on a 3A rating to protect downstream devices and speed system recovery.
