Cooper/Bussmann - MDM-1/4 - Fuse. 1/4Amp 250V. Slo-Blo, Package of 5.

These fuses avoid needless blows from starting currents or surges. They have a fuse link which operates only on very high overloads or short‑circuits‑they have a thermal cutout Which functions on low overloads‑ the thermal cutout cannot operate quickly at any load, hence long time‑lag is obtained. Yet protection is afforded against short‑circuits or continued overloads.

1/4 Amp 250V.

Time delay Slo-Blo.

Glass tube.

Fuse Type: Time Delay / Slow Blow          

Fuse Size / Group: 7.14 mm x 31.75 mm (0.28" DIameter x 1.25" Long")
