SIRIUS 3RB3 Electronic Overload Relays

Siemens SIRIUS 3RB3 Electronic Overload Relays feature a 0.1A to 115A seamless current range and are designed for inverse-time delayed protection of electrical loads under normal and heavy starting. The relays protect against excessive temperature rises due to overload, phase asymmetry, or phase failure. The 3RB31 electronic overload relays also allow internal ground fault detection. This fault detection feature provides protection of loads against incomplete ground faults due to damage to the insulation material, moisture, and condensed water. Siemens Sirius 3RB3 Electronic Overload Relays are suitable for operation with frequency converters and are manufactured in accordance with environmental guidelines and contain environmentally friendly and reusable materials. The devices comply with important worldwide standards and approvals.
