Quick Summary

Eaton Power Defense MCCB helps protect electrical panels in industrial settings. Engineers often struggle with arc-flash risk and downtime caused by nuisance trips, especially in compact control panels. Industry standards such as CE marking for Europe, IP-rated enclosure protection, and SIL considerations in safety systems guide this choice. The Power Defense approach combines tamper-resistant trip units with robust protection to mitigate operator access risks and accidental resets. By integrating tamper protection and reliable protection features, this MCCB supports faster commissioning, easier maintenance, and higher panel availability. For procurement teams, compatibility with standard Eaton enclosures and long-term ownership cost reductions matter as much as protection.

FAQs

When installing the 5108A03H02 MCCB, verify space within the panel to accommodate a standard molded case breaker footprint, confirm compatibility with current MCCB frames, and ensure wiring torque and conductor sizing meet manufacturer guidelines. Use the UPC for quick procurement and document the catalog number for asset tracking.
Tamper protection wire seals deter unauthorized resets and access to the trip unit, supporting regulatory compliance and safer operation. This feature is particularly valuable in environments with high workforce turnover or strict access controls, reducing the risk of accidental or intentional changes that could compromise protection settings.
Yes. The Power Defense approach is designed to improve arc-flash safety by providing reliable fault interruption and tamper-resistant protection. In industrial environments such as automotive, packaging, and processing facilities, this helps minimize exposure to high-energy faults and supports compliance with safety standards.
Key dimensions include a depth of 254 mm and a height and width of 0.254 mm each, with a weight of 13.6 g. Catalog Number is 5108A03H02 and UPC is 786689861100. Use these details for BOMs, space planning, and procurement workflows to ensure proper fit and traceability.
The device reduces downtime through reliable interruption and tamper-resistant protection, which lowers unplanned maintenance and resets. Improved safety and easier commissioning also shorten project timelines and enable longer interval between service interventions, contributing to lower total cost of ownership over the equipment lifecycle.
