Siemens Low Voltage Control Gear

Siemens Low Voltage Control Gear has everything you need for switching, protecting and starting loads. Products for monitoring, control, detection, commanding, signaling and power supply round off the spectrum of industrial controls.

3RH Contactor Relays are available in a selection of control supply voltages, they also have the option of a permanently mounted auxiliary switch block.

3RT Contactors up to 250kW offer optimum contact reliability and an extremely high level of ruggedness. Futhermore, compact electrical cabinets can be configured with high packing densities.

3RN Monitoring Relays are used for direct monitoring of the motor winding temperature using temperature-dependant resistors (PTC's, Type A) that are directly installed in the motor winding by the manufacturer.

3RV Motor Starter Protectors are compact, current limiting motor starter protectors which are optimized for load feeders. The motor starter protectors are used for switching and protecting induction motors of up to 45kW at 400 V AC and for other loads with rated currents of up to 100A.

3RB2 Solid-State Overload Relays up to 630A with internal power supply have been designed for inverse-time delayed protection of loads with normal and heavy starting against excessive temperature rises due to overload, phase unbalance or phase failure.

3RU1 Thermal Overload Relays up to 100A have been designed for inverse-time delayed protection of loads with normal starting against excessive temperature rises due to overload or phase failure.
