People Electric · Thermal Overload Relay
Product overview
People Electric JRS2 thermal overload relays protect compatible AC motor starter circuits against overload and phase loss. This page offers the three combined-mounting frames identified in the original photographs and manufacturer handbook, with frame-specific current intervals. Select a range containing the actual motor current and confirm the matched CJX1 contactor.

Only the documented combined-mounting frames and intervals shown in the selectors are offered. The ambiguous 0.1–016A entry and the 4–6.3A table row containing an unlisted frame code are excluded for affected frames. Larger-frame trip-class and frame-code discrepancies are not carried into this listing. Photos are original series examples; confirm the exact current interval and matched contactor before ordering.
Typical applications
- Overload and phase-loss protection of compatible AC motor starters.
