Bussmann TCF3RN Time-Delay Fuse – Reliable Circuit Protection

Overview

The Bussmann TCF3RN is a high-performance time-delay fuse designed for robust circuit protection in AC electrical systems. Engineered to withstand temporary inrush currents (e.g., motor startups or transformer energization) without nuisance tripping, it provides dependable defense against sustained overloads and short circuits. Ideal for industrial controls, HVAC systems, appliances, and power supply units.

Key Features

• Time-Delay Design: Allows brief current surges (up to 10x rated current) while protecting against prolonged overloads.
• Voltage Rating: 250V AC for versatile commercial/industrial applications.
• Current Rating: 3A (standard TCF3RN variant; verify specific amperage for your model).
• High Interrupting Capacity: 10kA @ 250V AC – safely contains high-fault currents.
• Compact & Durable: 1¼” x ¼” (5x20mm) glass-body cartridge for easy visual inspection of the fusible element.
• Compliance: UL Listed (Class CC) and CSA Certified for safety compliance.
• Temperature Tolerance: Stable performance from -55°C to 125°C.

Applications

• Motor control circuits
• Transformers and solenoids
• Power supplies and inverters
• Lighting ballasts
• Industrial automation panels
