1210L150/16WR Circuit Protection

PTC Resettable Fuses, such as the 1210L150/16WR, are designed to protect sensitive electronic and electrical equipment during a fault event, while allowing them to remain fully functional after the fault is cleared.

The 1210L150/16WR comprises a PTC (positive temperature coefficient) and a wirewound element. The PTC is a small thermal trip device that is connected in series with the protected circuit. When a high surge of current is detected through the protected line, the PTC will begin to heat up. This causes its resistance to increase exponentially over time, eventually reaching a thermal trip temperature, usually at around 150°C.

At the same time, the wirewound element is also heating up and its resistance is increasing. This helps to dissipate the excessive energy created by the fault until the PTC reaches its thermal trip temperature. When the PTC reaches its thermal trip temperature, it will effectively open the circuit, thus cutting off the power supply in order to protect the equipment.

Once the fault is cleared, the PTC will slowly cool down and its resistance will start to decrease. As the PTC cools, the wirewound element will begin to dissipate the energy stored in its coils, thus allowing the PTC to reset itself. This resetting process usually takes only a few seconds.

The 1210L150/16WR is primarily used in the industrial and consumer markets for applications such as HVAC, motor controls, and process industrial. It is also being increasingly used in mobile devices, such as smart phones and tablets, and other applications requiring surge protection.

The 1210L150/16WR is available in a variety of standard sizes and configurations, making it a reliable and cost-effective solution for a variety of applications. In addition, it is also RoHS compliant, making it a great choice for applications with safety requirements.

The 1210L150/16WR is a highly reliable, durable and efficient PTC Resettable fuse and provides reliable protection from surge and transient events. It is designed as a cost-effective solution that is easy to install and maintain.
