Technical Specifications
| Adjustable overload range | You set the relay to match motor full-load current instead of using one fixed trip point. |
|---|---|
| Phase-failure protection | Helps stop a 3-phase motor when one phase is lost and current imbalance starts overheating the windings. |
| Manual / automatic reset | Useful when you want either technician acknowledgement after a trip or automatic return after inspection. |
| Contactor pairing | Designed to sit with motor-starter hardware, especially magnetic contactor-based DOL panels. |
| IEC motor-control standard context | The JR28/JR28S family is published for motor overload and phase-failure protection in IEC 60947-4-1 style applications. |
Available Options
