Description
The Eaton Bussmann TCF80RN (Catalog Number: TCF80RN) is an 80 A Class CF Low-Peak™ CUBEFuse™ time-delay, dual-element current-limiting fuse engineered for space-saving power distribution and industrial control systems. Built from durable glass-filled polyethersulfone (PES) in an IP20 finger-safe cube footprint with plug-in blade end connections, this non-indicating fuse provides an exceptionally high interrupting rating of 300 kAIC at 600 VAC (50/60 Hz) and 100 kAIC at 300 VDC.
Featuring a 10-second response time at 500% overload, the TCF80RN safely absorbs temporary starting surges from motors and transformers without nuisance tripping, while delivering rapid current limitation and low energy let-through under short-circuit fault conditions. Designed for chassis or 35 mm DIN rail mounting, it is CE marked, RoHS compliant, UL Listed, and CSA Certified.
Key Features
- Finger-Safe Class CF Cube Footprint: Innovative IP20 finger-safe CUBEFuse™ design integrates maximum space savings with safety protection.
- Dual-Element Time-Delay Design: Delivers a 10-second response time at 500% overload to withstand heavy inductive motor starting inrush currents with low watts loss.
- High Interrupting Ratings: Provides robust fault protection rated at 300 kAIC at 600 VAC (50/60 Hz) and 100 kAIC at 300 VDC.
- Versatile Mounting: Mounts on chassis or standard 35 mm DIN rail configurations for flexible panel integration.
- Glass-Filled PES Construction: High-impact black housing engineered for thermal efficiency and long operational life in harsh environments.
