Cutler-Hammer C316FNA3 Motor Thermal Overload Relay Used
Safeguard industrial automation systems and multi-phase motor starters without paying full retail distributor expenses. This fully verified, pre-owned Cutler-Hammer C316FNA3 Thermal Overload Relay delivers highly responsive electromechanical safety, automatically breaking input control circuit lines to prevent terminal equipment destruction from sustained electrical overloads, phase balance issues, or stalls.
| SPECIFICATION / VALUE | DETAILS & BENEFITS |
|---|---|
| Item Condition | USED — Thoroughly inspected second-hand protection element. Casing structural walls are fully intact, side terminal slots are clear, and the master data configuration plate is perfectly readable. Made in Germany. |
| Product Type | Bimetallic, ambient-compensated thermal overload protection relay block. |
| Model / Series Reference | Series A2 / Part Number Code C316FNA3 (Conforms strictly to international standards including IEC/EN 60947-4-1 standards). Certified by UL, CSA, and CE markings. |
| Tripping Characteristics | Class 10 Relay Rating. Calibrated to execute quick-acting safety breaks when sustained electrical currents cross a threshold limit of 125% of the dialed Full Load Current (F.L.C.) settings. |
| Insulation & Voltage Limits | Rated Insulation Voltage (Ui) of 690V AC with a high-capacity Rated Impulse Withstand Voltage (Uimp) tracking of 6 kV. Rated for standard industrial control setups up to 600V maximum under UL/CSA rules. |
| Integrated Auxiliary Switches | Features 1 NC contact loop (terminals 95-96 / B600 pilot rating) and 1 NO contact loop (terminals 97-98 / C600 pilot rating). Supports exact automated alarm indicators and relay interlocking, maintaining identical safety polarity rules above 300V. |
| Contactor Interlock Fitment | Engineered directly for installation and plug-in fitment alongside Eaton Cutler-Hammer contactor lines including types CE15AN, BN, CN, DN, EN, FN, as well as standalone C306TB1 base mounting adapter tracks. |
| Value Advantage | Genuine European-built industrial switchgear by Eaton Cutler-Hammer. Ambient-compensated internal bimetallic mechanics prevent false or early trip errors caused by shifting temperatures inside dense electrical enclosure cubes. Offers property maintenance personnel an identical component replacement choice at a highly reduced pre-owned price point. |
