Eaton Resettable Fuse, 50A Current Rating, 6V Voltage - PTSLR12066V300

This resettable fuse provides overcurrent protection for electronic systems by interrupting excess current and self‑resetting once conditions return to normal. Designed for surface‑mount applications, it suits Compact assemblies where repeatable circuit protection is required and offers stable operation across a wide ambient range.

Features and Benefits:

• 50 A nominal current rating for high‑capacity protection
• Trips at 6 A to prevent sustained overloads
• Hold current 3 A maintains continuity under normal load
• Maximum resistance 0.03 Ω minimises voltage drop
• Power dissipation 0.8W controls thermal stress during events
• Time‑to‑trip 4 s offers predictable response to faults

Applications

• Suitable for automotive electronics with wide temperature swings
• Ideal for power distribution modules in automation equipment
• Used for protection of battery management circuits in EV prototypes
• Can be used for safeguarding motor drive control boards
• Used with Compact consumer electronics requiring resettable protection

What temperature range can it tolerate in operation?

It operates between -40 °C and 85 °C, enabling use in cold starts and elevated ambient environments.

How does its electrical resistance affect system performance?

The low resistance—down to 3 mΩ and up to 0.03 Ω—keeps series voltage loss and heat generation minimal during normal operation.

What mounting and packaging considerations are there for production?

It is supplied on reel for pick‑and‑place assembly and configured for surface‑mount placement.

How quickly will it react to an overcurrent condition?

Under defined overload it reaches the trip point in approximately 4 seconds, providing a balance between nuisance trips and protection.
