Bussmann MDA-15-R Time Delay Fuse

Overview

The Eaton Bussmann MDA-15-R is a high-performance time-delay fuse designed for reliable circuit protection in demanding electrical systems. Its precision engineering ensures optimal defense against overcurrent events while accommodating temporary inrush currents without nuisance tripping. Ideal for industrial, commercial, and HVAC applications, this fuse combines robust construction with Bussmann’s trusted safety standards.

Key Features

• Time-Delay Design: Withstands initial surge currents (e.g., motor startups, transformer energization) while providing reliable protection against sustained overloads and short circuits.
• Dual-Element Technology: Features a thermal-responsive element for overloads and a high-speed element for short-circuit interruptions, ensuring balanced protection.
• Ceramic Construction: Engineered with a durable ceramic body for superior heat resistance and arc quenching capabilities.
• Rejection Base (R-Style): Prevents installation of incorrect fuse types, enhancing safety and compliance.
• Standard Size: Compact 1-1/4″ x 1/4″ (5x20mm) dimensions for universal compatibility with fuse holders and panels.
