Features
Applications
Used in military and commercial satellites and spacecraft including manned space vehicles
- Protection of power supplies, batteries and solar arrays
- Isolation of redundant and branch circuits
- Short circuit protection from fired squib and jettison circuitry
Features
- Consistent clearing times achieved at overload currents regardless of vacuum conditions
- Solid body construction without outgassing and not subjected to the de-rating factors of MIL-STD-975
- Solid body construction capable of withstanding greater vibration and shock exposure without damage
- Positive temperature coefficient of fuse element causing resistance to increase (prior to opening) thereby preventing absolute short to the power source
- Internal construction ensuring that arc, plasma and vapor are contained within the fuse package during overload current conditions
- High-reliability fuse series with over 29 million hours of life testing without a failure
- Groups A/B data supplied with each shipment and Group C inspection optional
