FAQs
The FWX-150A supports blade end x blade end connections and stud mounting, offering flexibility for both plug-in style panelboards and screw-in mounting in control cabinets. This combination simplifies retrofits and new installations while preserving compact enclosure footprints. It is important to verify enclosure clearance and connector availability during design reviews to avoid space conflicts.
FWX-150A is rated for 150A RMS with an interrupt rating of 200 kAIC at VAC conditions and 50 kAIC at 250 VDC. It dissipates approximately 15.7 W during operation. These ratings make the FWX-150A suitable for protecting motor feeders and power distribution in industrial environments, while meeting performance requirements for high-energy faults.
Yes. The FWX-150A high speed fuse is designed for fast fault interruption in motor drive circuits and related protection schemes. Its high interrupt rating helps isolate faults quickly, limiting damage to drives and wiring. When selecting for motor protection, ensure the fuse current rating matches the system’s run and fault current profiles and consider the DC-link requirements where applicable.
FWX-150A carries CE Marking and RoHS compliance, along with CSA Certification and UL Recognized status. These certifications confirm compliance with European and North American safety and environmental standards, easing procurement for regulated facilities and reducing compliance risk across global sites where equipment must meet strict industrial guidelines.
