FAQs
The P3BFDC3125G is designed as a plug-in three-pole circuit breaker unit compatible with Eaton busway assemblies. Its dimensions (12.36 in L, 21.2 in H, 5.43 in W) and 25 lb weight support straightforward mounting in standard panels or busway adapters. Ensure busway access clearance and secure grounding per 50% internal ground specification, and verify clearance for plug-in removal during maintenance.
This unit provides a 125A amperage rating with interrupt ratings of 200 kAIC at 240 Vac, 100 kAIC at 480 Vac, and 35 kAIC at 600 Vac. It carries ANSI and CSA certifications, UL 857 certification, and IEEE certification, ensuring compliance for safety, performance, and interoperability in North American applications.
Yes. The breaker is rated for 240 Vac (200 kAIC), 480 Vac (100 kAIC), and 600 Vac (35 kAIC), making it versatile for multi-voltage busway protections common in industrial facilities and diverse process environments.
50% Internal Ground means a portion of the grounding path is integrated inside the module, reducing external wiring complexity while maintaining a reliable fault path. This improves installation speed and minimizes field wiring errors, but ensure proper system grounding design is followed for site-specific safety requirements.
Warranty aligns with Eaton’s policy SP 25-000, offering one year from installation or eighteen months from shipment, whichever comes first.
