FAQs
For engine-generator protection, ensure a three-pole FG frame fits the panel footprint and that metric mounting hardware is used. Utilize the line side end cap (with optional load side) to simplify wiring, and confirm 60 Hz operation at 600 Vac to match the generator specifications. This setup supports straightforward retrofits and quick fault isolation.
The device provides 45 A at 600 Vac with fixed thermal and magnetic trips (T186). Its interrupt ratings are 18 kAIC at 240 Vac and 14 kAIC at 480 Vac, enabling robust protection for generator-driven loads. Generator ratings include 16 kVA/13 kW at 240 Vac, 32 kVA/29 kW at 480 Vac, and 41 kVA/32 kW at 600 Vac.
Yes, this is a three-pole FG-frame molded case circuit breaker designed for engine-generator protection. It uses metric mounting, line side end caps, and an optional load side, aligning with generator control panels. The device coordinates well with standard 60 Hz generator configurations and supports dependable on-site protection in generator rooms and power plants.
