The SIEMENS 3RU2136-4GB1 is a thermal overload relay from the Siemens SIRIUS 3RU series. It is a dedicated protection device designed to safeguard three-phase electric motors from damage caused by sustained overloads, phase failure, and phase imbalance by interrupting the motor control circuit when a fault is detected.
The SIEMENS 3RU2126-4CB1 is a thermal overload relay from the Siemens SIRIUS 3RU series. It is a dedicated motor protection device designed to safeguard electric motors from damage caused by sustained overloads, phase failure, and phase imbalance by monitoring motor current and interrupting the control circuit upon fault detection.
The SIEMENS 3RU2116-1KB0 is a thermal overload relay from the Siemens SIRIUS 3RU series. It is a dedicated protection device designed to safeguard electric motors from damage caused by prolonged overloads, phase failure (loss), and phase imbalance by monitoring the motor's current and interrupting the control circuit when a fault is detected.
The SIEMENS 3RU2116-1CB0-Z W96 is a thermal overload relay from the Siemens SIRIUS 3RU series. Designed for motor protection, it safeguards electric motors from damage caused by sustained overloads, phase failure, and phase imbalance by monitoring the motor current and interrupting the control circuit upon detecting a fault condition. The suffix "W
The SIEMENS 3RU2116-0GC1 is a thermal overload relay from the Siemens SIRIUS 3RU series. It is an essential protection device designed to safeguard electric motors from damage caused by sustained overloads, phase failure, or phase imbalance by monitoring the motor's current and tripping the control circuit upon detecting a fault.
