Eaton ATM blade fuse ATM-20 - 32 Vdc, 1 kAIC RoHS
Part Number: ATM-20
Quick Summary
ATM blade fuse protection from Eaton delivers reliable DC overcurrent protection for low-voltage industrial circuits. Engineers often struggle with limited panel space, incorrect amperage, and fuses that don’t indicate when they have blown, complicating maintenance. The ATM-20 offers a 20 A rating, 32 Vdc operation, 1 kAIC interrupt rating, a color-coded yellow housing, non-indicating design, and RoHS compliance to simplify sourcing. Designed for compatibility with standard blade-fuse holders in control panels and OEM assemblies, it enables fast, error-free installation and straightforward replacement, reducing downtime and service costs. By aligning with Bussmann series standards, it also supports inventory rationalization and predictable performance across critical automation loads.

Eaton Specification Sheet - ATM-20
The 20 A amperage rating combined with a 32 Vdc operating voltage and a 1 kAIC interrupt rating provides precise protection for DC circuits in control panels and automation equipment, preventing nuisance trips while enabling safe startup sequences. This translates to fewer unexpected outages and better uptime for critical lines like PLC power rails and motor drives. Color coding in yellow facilitates quick visual identification during assembly and maintenance, while the non-indicating design keeps panel layouts clean and reduces confusion in high-density wiring environments. RoHS compliance helps you meet regulatory and sustainability goals without sacrificing performance. The fuse is compatible with standard blade fuse holders, enabling fast swaps and minimizing downtime during maintenance or expansion. The zinc fuse element with colored plastic housing delivers durable operation and clear identification under industrial conditions. Compatibility with existing Bussmann series components supports streamlined sourcing and consistent performance across product lines.

FAQs
ATM-20 is designed for standard automotive blade-style holders used in control panels. Ensure the holder supports 32 Vdc and 20 A, confirm proper blade contact cleanliness, and verify the connector alignment to prevent intermittent connections. Use compatible mounting and enclosure spaces to maintain ease of access for replacement.
The 20 A rating, 32 Vdc operating voltage, and 1 kAIC interrupt capacity provide precise protection for DC circuits while limiting fault current. Use ATM-20 in applications like DC power rails for PLCs or motor drives, ensuring loads stay within these specifications to avoid nuisance blows or inadequate protection.
Yes, the ATM-20 is RoHS compliant, meaning it restricts hazardous substances to meet environmental and regulatory requirements. This simplifies procurement for manufacturers pursuing sustainability goals and helps maintain compliance across automotive, industrial, and automation sectors.
Non-indicating fuses do not show blown status visually, so integrate periodic diagnostics with a multimeter or panel monitoring to verify continuity. Maintain a stock of spare ATM-20 fuses, label locations clearly, and incorporate routine checks into preventive maintenance to minimize unscheduled downtime.
The standardized form factor and yellow color code streamline installation and reduce wiring errors, shortening maintenance windows. Reliability is supported by a robust zinc fuse element and colored housing for easy identification, while RoHS compliance eases procurement and supplier consistency, delivering lower total cost of ownership over time.
