Waytek Inc. introduces PolySwitch circuit protection devices as a resettable over-current protection solution in vehicle, heavy truck and equipment wire harnesses.
- Provides resettable over-current protection in a 2.8mm footprint and solid state design
- Easy drop-in replacement for mini fuses and type II circuit breakers in 12V vehicle systems
- Features a solid state design with no moving parts or contacts to arc, erode or weld together
- Provides longer lasting and more reliable circuit protection than circuit breakers or fuses
- Operates with a resistance switching action that latches immediately following an overcurrent tripping condition
- Provides virtually constant power consumption across a voltage range of 4 to 14V
- Has less thermal cross talk between devices than Type II bimetal circuit breakers due to low power dissipation and flatter thermal derating
- Rated for temperatures between -40 and 257 F
- Passes more current at higher temperatures than bimetal circuit breakers
- Suitable for harsh underhood applications
- Bright color-coded housings and rated current values printed on the top of the devices make replacement easy, and help prevent installation errors
- Exposed probe points facilitate inspection and faultfinding, helping lower labor time and costs
