Eaton Ceramic Cartridge Fuse 7A Current Rating 250V AC 6.3 x 32 mm Time Delay MDA-7-R

The Eaton MDA-7-R Ceramic Cartridge Fuse is a robust electrical protective device designed for time-delayed overcurrent protection in AC circuits. Featuring a 7A current rating and 250V AC voltage capacity, it is optimized for applications with short-duration inrush currents such as motor starts and capacitor charging.

This fuse utilizes a ceramic body to withstand thermal stress and mechanical impacts, ensuring integrity under demanding operating conditions. Its T-class slow-blow time-delay characteristic allows temporary current surges to pass while effectively interrupting sustained overloads, reducing unnecessary interruptions and enhancing equipment reliability.

Operating temperature ranges from -55°C to 125°C make it suitable for varied industrial environments. It supports protection of industrial power supplies, control units, and automation modules, especially where soft-fault tolerance is necessary.

The fuse size conforms to the common 6.3 x 32 mm cartridge standard, compatible with widely used fuse holders. Eaton’s MDA series fuse is UL 248-14 certified, reflecting adherence to industry safety standards.

Applications include protection of sensitive electronic devices, industrial automation controls, and other equipment vulnerable to transient faults. The fuse’s time-delay behavior is ideal for circuits where startup surges occur frequently, preventing nuisance interruptions without compromising safety.

The ceramic construction ensures durability and thermal stability. 7A current rating supports moderate load protection requirements. 250V AC voltage rating fits standard mains power systems. Time delay characteristic accommodates short inrush currents without tripping.

Wide operating temperature range enhances environmental tolerance. UL 248-14 approval guarantees compliance with international safety norms. Standard 6.3 x 32 mm size enables direct replacement in existing assemblies.

Ensure reliable circuit protection with Eaton’s MDA-7-R ceramic cartridge fuse for industrial, laboratory, and automation applications. Explore similar Cartridge Fuses on EnvMart for varied protection needs.
