This compact design (7 in L, 5 in W, 6 in H and 4 lb) fits engine compartments and control panels without compromising performance. Business impact – predictable protection for smaller engine-generator loads, simplified wiring, and reduced panel footprint. Application – engine-generator sets that run at 60 Hz with tight mounting constraints. Feature – Fixed trips and interrupt ratings: It uses fixed thermal and magnetic trips (T186) with 18 kAIC at 240 Vac and 14 kAIC at 480 Vac, enabling fast interruption for short circuits. Business impact – minimizes arc-flash exposure, maintains generator protection coordination, reduces downstream damage and downtime. Application – critical engine-generator protection where quick fault clearance matters. Feature – Generator coverage and output flexibility: Generator ratings of 9 kVA/7 kW at 240 Vac, 18 kVA/14 kW at 480 Vac, and 23 kVA/18 kW at 600 Vac. Business impact – supports multiple generator outputs with a single protective device, reducing inventory and simplifying procurement. Application – varying engine-generator configurations across 240, 480, and 600 Vac systems. Feature – Certifications and compliance: IEC 947-2 ratings, UL Listed, CSA Certified, and UL 489 compliance. Business impact – regulatory assurance across regions, simplified supplier qualification, and lower procurement risk. Application – global deployments in industrial, transport, and utility environments. Feature – Physical characteristics and warranty: Dimensions 7 x 5 x 6 in and weight 4 lb; warranty per Eaton policy 25-000 (one year from installation or 18 months from shipment). Business impact – easier panel integration, predictable maintenance planning, and reliable support resources. Application – control panels, engine compartments, and field installations requiring compact protection.
