The Bussmann family of PolyTron™ PTC devices is ideally suited for protecting applications sensitive to high ambient operating temperatures or subject to frequent overcurrent conditions. PTCs operate as a positive temperature coefficient device. High temperatures and excessive current will cause the device resistance to increase until it limits the unsafe current level. Upon reaching the design temperature/current limit, the PTC will effectively “open” the circuit to provide protection from the overcurrent or elevated ambient temperature condition. Once the fault is removed or the ambient temperature cools, the PTC will automatically “reset” and conduct safe current levels again, allowing current to flow through the circuit. PTCs are commonly used in applications where constant uptime is required and/or in circuits not easily accessible by a user or service technician. Available in surface mount and radial packages, Bussmann PolyTron PTC devices help improve the safety and reliability of customer equipment worldwide.
