Mersen Amp-Trap ATM Midget Fast-Acting Fuse, 600VAC/600VDC
The Mersen Amp-Trap® ATM is a midget fast-acting fuse rated 600VAC and 600VDC with a 100kA interrupting rating, giving it a wide range of applications beyond what other midget fuses can cover. The family is also offered in special 30/35, 30/40, and 30/50 ampere ratings for applications such as capacitor protection — these are still considered 30A fuses dimensionally, but are built to withstand much higher inrush currents and tougher duty cycles. Terminals are ferrule-style with tin-plated copper construction, mounted via clip. Note: this fuse is not for Branch Circuit Protection.
Key Features
- Voltage Rating: 600VAC / 600VDC rated for use in both AC and DC circuits.
- Interrupting Rating: 100kA AC max interrupting/breaking capacity (I1) for reliable protection against high fault currents.
- Fast-Acting Characteristic: Fast-acting speed for quick response to overcurrent conditions, well suited to capacitor protection duty cycles.
