NEW ARRIVAL SIEMENS 3RU2116-0HB0 Thermal Overload Relay Now In Stock
We are pleased to announce the arrival of the SIEMENS 3RU2116-0HB0 thermal overload relay. As a key component of the SIRIUS 3RU2 series, this device is designed to provide reliable overload protection for industrial motors, ensuring safe and stable operation of electrical systems.

Product Description of 3RU2116-0HB0
The SIEMENS 3RU2116-0HB0 is a thermal overload relay with an adjustable current range of 0.55 - 0.80 A. It is suitable for a maximum rated operating voltage of 690 V AC and has a contact rating of 800 mA at 24 V AC/DC. The device features 3 pins for the main circuit and offers 1 NO (normally open) + 1 NC (normally closed) auxiliary contacts. It provides high - precision protection for motor circuits and is ideal for applications requiring small - current motor protection. The relay has a compact design with dimensions of 70 mm height, 20 mm width, and 80 mm depth. Its front panel and terminals both meet IP20 protection standards. It is resistant to vibration (8g/11 ms, in accordance with IEC 60068 - 2 - 27) and has a typical total active power loss of 4.5 W .
The relay is designed to protect motors from overload damage by monitoring current and triggering protective mechanisms when overload conditions occur. It offers adjustable overload protection settings, enabling precise adaptation to different motor loads and operating conditions. Its thermal relay technology ensures reliable operation even under prolonged overload conditions. The device is easy to install and integrate into motor control systems and supports a wide range of motor protection applications, including motor starters and motor control circuits.
