4. Product Introduction
The Socapel PAM-R1N-H8F-AP-P V10800 (H006.7538) is a 3-pole electromechanical contactor rated 32 A AC-3 at 400 V. It features a 230 V AC 50/60 Hz coil and integrated 1 NO + 1 NC auxiliary contacts for control feedback or interlocks.
The unit mounts on standard 35 mm DIN rail or directly to a panel and uses screw-clamp terminals. It is designed for motor starting, resistive heating, and general industrial power switching where a compact contactor with built-in auxiliaries is required.
5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Contactor fails to pick up | Missing or incorrect coil voltage | ✅ High | Measure 230 V AC at coil terminals with command active | Verify control voltage source and wiring; check for open coil |
| Contactor chatters or buzzes | Low coil voltage or dirty contact faces | ✅ High | Measure coil voltage under load; inspect main contact surfaces | Stabilize supply voltage; clean or replace contacts if pitted |
| Auxiliary contacts do not change state | Worn or stuck aux block | ✅ Medium | Continuity test NO and NC auxiliaries with contactor energized and de-energized | Replace auxiliary contact block or complete contactor |
| Terminals overheat | Loose screws or current overload | ✅ High | Check terminal torque; measure actual load current vs. 32 A rating | Retorque all terminals; confirm load is within AC-3 rating |
| Contactor remains closed after power removal | Welded contacts or residual magnetism | ✅ Medium | Manually verify free armature movement after coil de-energized | Replace unit; investigate upstream short-circuit or overload cause |
If the issue persists after these checks, supply measured coil voltage, load current readings, and clear photos of the terminals and nameplate to technical support.

6. Frequently Asked Questions (FAQ)
Q: What does the V10800 designation indicate?
A: It identifies the specific production revision of the PAM-R1N-H8F-AP-P. It is functionally equivalent to earlier revisions such as V10700 for standard applications. Always match the exact part number to the original equipment list.
Q: Can this contactor be used with a 24 V DC control circuit?
A: No. The H8F code specifies a 230 V AC 50/60 Hz coil. A different coil version is required for DC or other AC voltages. Using the wrong coil will prevent reliable operation or damage the unit.
Q: Are the auxiliary contacts rated the same as the main poles?
A: No. The 1 NO + 1 NC auxiliaries are intended only for low-current control signaling and interlocks. Do not switch motor or high-power loads through the auxiliary contacts.
Q: Is the PAM-R1N-H8F-AP-P V10800 still in active production?
A: The Socapel PAM series remains available, but specific revisions such as V10800 may be supplied from remaining inventory. Confirm form, fit, coil voltage, and auxiliary configuration before ordering as a direct replacement.
Q: What is the difference between the R1N and R3N versions?
A: The R1N is the standard 3-pole contactor. The R3N is a 4-pole version used when neutral switching or an additional pole is required. Select the correct pole count for the application.
Q: Why is the secondary-market price often lower than original list?
A: These units are commonly available as new surplus from panel builders or decommissioned systems. They are fully functional when verified, but they typically carry a seller warranty rather than a current factory warranty.
Q: What mounting methods are supported?
A: Standard 35 mm DIN rail snap-on mounting or direct panel mounting via the base. Provide adequate clearance for heat dissipation and arc suppression when installing inside an enclosure.
