Siemens Industrial Controls 3RU2136-4FB0 Thermal Overload Relay S2 Class10 28-40A

Siemens Industrial Controls 3RU2136-4FB0 Thermal Overload-Relay is used for motor protection in HVAC systems. This S2 size relay has a current range of 28-40A and Trip Class 10 to protect motors from overheating and phase failure by cutting the power supply when an overload condition occurs. In compressors fans and pumps, for instance, it is widely used to assure reliable operation and to prolong motor's life time. The compact design of the relay makes it convenient to integrate into control panels, as well as providing a more precise thermal response than based on a passive heat sink. Reduced downtime, improved safety, and cost effective protection are the benefits of having it as an essential part.
