The Littelfuse LVR200S-240 is a polymeric positive temperature coefficient (PPTC) resettable fuse designed for overcurrent protection in a wide range of AC applications. With a hold current of 2.0 A and a rated voltage of 240 VAC, this device provides reliable, resettable protection against short circuits and overloads.
Key Features
- Resettable overcurrent protection: automatically returns to normal after fault is removed
- Rated for 240 VAC operation, suitable for line-voltage applications
- Radial leaded package for through-hole mounting, compatible with standard PCB assembly
- Low resistance minimizes power dissipation during normal operation
- Wide operating temperature range (to be verified)
- Recognized by major safety agencies (to be verified)
Applications
- Power supplies and transformers
- Motors and solenoids
- Lighting ballasts and LED drivers
- Industrial controls and HVAC equipment
- Security and fire alarm systems
Selection Guidance
When selecting the LVR200S-240, consider the circuit's normal operating current (should be below the hold current), the maximum ambient temperature, and the available fault current. The device is designed to operate within a specified temperature range; derating may be required at elevated temperatures. Verify the exact electrical characteristics and agency approvals from the datasheet before final design.
