Systematic reduction of components is a major reason for a successful cost-saving design. And fewer components normally help save space and allow for designing compact products.
The appliance inlet module X3120-B combines three functions within a single component: A C14 appliance inlet, a rocker switch and resettable overcurrent protection. In this module the two latter functions are provided by E-T-A’s wellproven 3120-N circuit breaker/switch combination.

RTS Tripping Temperature > 175°C
Improved Protection of Power Semiconductors
• Protects power semiconductors from thermal runaway
• SMD reflow solderable up to 260 °C
• Tested for usage up to 60 V
• Integrated current measuring sensor (shunt)
Schurter RTS thermal fuse, successfully launched in 2018, gets a new variant with a tripping temperature of >175°C. The RTS is a particularly compact overtemperature protection device for power semiconductors in SMD technology for highest demands.
RTS stands for Reflowable Thermal Switch. It was developed to protect highly integrated power semiconductors from overheating. Prior to mechanical activation, the new thermal fuse can be soldered on conventional reflow soldering machines with profiles up to 260 °C.
Protection Against Thermal Runaway
Thermal runaway refers to the overheating of a power semiconductor due to a self-reinforcing, heat-producing process. One of the reasons is the trend towards increasing power density and miniaturization of electronic circuits. The RTS protects these power semiconductors against thermal runaway. In such an event, the thermal fuse acts as a fail-safe device and reliably interrupts the circuit from as early as 175 °C and thus addresses the operating temperatures of common power semiconductors even better.
Minimal Footprint
The new overtemperature protection device comes in the same minimal dimensions and maximum breaking capacity despite its additional shunt functionality. On its small 6.6 x 8.8 mm footprint the RTS can handle operating currents of up to 130 A and rated voltages of up to 60 VDC.
Integrated Current Measuring Sensor (Shunt)
The shunt version has an integrated resistance with particularly low temperature dependence. This resistance, known as a shunt, enables precise current measurement and enables an additional – non-thermal – circuit protection, e.g. via a controller.

The IWPT sensor can be used with either an IWR-1 or IWR-5 receiver. A line-of-sight range of up to 1640 ft is possible depending on the wireless receiver used. (refer to datasheets IWR-1 & IWR-5 for further information)
Each device is temperature compensated, calibrated and supplied with a traceable serial number.
Features:
• Suitable for liquids and gases
• Pressure ranges from 0-1psi to 0-15psi gauge/abs
• Up to 1640 ft line-of-site range (depending on receiver)
• Piezo-resistive stainless steel sensor with stainless steel body
• Five-year battery life at 10 second transmission update rate
• Simple DIL switch pairing with the single or five channel receiver
• Single or five channel receivers available
• User-selectable transmission update rates
• User-selectable 1-5V or 4-20 mA receiver outputs
• Receiver clean contacts provide process alarm functions
Typical Applications Include:
• Simple cable replacement installation – dispense with expensive cable runs
• Environmental monitoring – rainwater harvesting, environmental engineering
• Facilities management – boiler rooms, laboratory testing, tank gauging
• Asset monitoring – tanks farms, process plants, HVAC and building management
