Bussmann MDQ-V Dual-Element Time-Delay Fuse, 250V Ferrule-End

Bussmann MDQ-V Dual-Element Time-Delay Fuse, 250V Ferrule-End

The Bussmann MDQ-V Series dual-element time-delay fuse from Eaton is a small-dimension electronic fuse built for relay and control circuit protection. Each fuse uses a glass tube body with nickel-plated brass ferrule-end caps for a secure ferrule end X ferrule end connection, and carries a voltage rating of 250 Vac, 32 Vdc (self certified) with a 35 AIC interrupt rating at 250 Vac. This MDQ-V family is available across amp ratings from 0.125A to 0.4A, with a dual-element design rated for a maximum 60-minute delay at 135% of rated current and a maximum 120-second delay at 200% of rated current, making it well suited to electronic relay and control circuits.

Key Features

• Compact Dimensions: 1.25 IN product length and .25 IN product width suit small-dimension electronic and control-circuit applications.
• Durable Construction: Glass tube body with nickel-plated brass endcaps for use with axial leads and caps.
• Ferrule-End Connection: Ferrule end X ferrule end termination for straightforward installation in relay and control circuits.
• Dual-Element Design: Two internal elements deliver time-delay performance, with a response time of 60 min maximum at 135% and 120 s maximum at 200% of rated current.
