Siemens 3RF2916-0JA13 Heating Current Monitoring

Siemens 3RF2916-0JA13 Heating Current Monitoring is a SIRIUS heating current monitoring relay that supervises current through a heating load and provides an electrical signal if the current deviates from the set range. It handles Ie up to 16 A, is rated for operation on 110–230 V on the monitored circuit, and uses a separate control supply of 24 V AC/DC. The unit supports a remote teach input or a version without a control connector for use with semiconductor relays or contactors, and a screw-terminal variant exists (3RF2916-0JA13-1KK0). This device is intended for heating applications such as resistance heaters, furnace elements, or other heater loads where monitoring the current ensures safe and reliable operation. The 3RF29 family to which it belongs is designed for heating current monitoring with an NC output configuration, enabling straightforward integration into control circuits while signaling faults or abnormal currents. With a compact, plug‑in footprint, it is suitable for panel or rail installations where precise current monitoring and quick fault indication are required, and it is specified for use with line voltages in the 110–230 V range and a 24 V control supply, consolidating monitoring and control in a single Siemens module.
