Description
The Eaton Bussmann TCF70RN (Catalog Number: TCF70RN, UPC: 051712236164) is a 70 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 a finger-safe cube footprint with 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 TCF70RN safely absorbs temporary starting surges from motors and transformers without nuisance tripping, while delivering rapid current limitation under short-circuit fault conditions. Designed for chassis or 35 mm DIN rail mounting when used with TCFH100N holders or CCP2-3-100CF disconnect switches, it is CE marked, RoHS compliant, UL Listed, and CSA Certified.
Key Features
- Finger-Safe Class CF Cube Footprint: Innovative CUBEFuse™ design integrates small-footprint space savings with built-in finger-safe safety protection.
- Dual-Element Time-Delay Design: Delivers a 10-second response time at 500% overload to withstand heavy inductive motor starting inrush currents.
- 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 & Holder Compatibility: Mounts on chassis or standard 35 mm DIN rail via TCFH100N fuse holders or CCP2-3-100CF switch disconnectors.
- Glass-Filled PES Construction: High-impact black housing engineered for thermal efficiency and long operational life in harsh environments.
