4. Selección & Replacement Guidelines
5. Compatibility Rules

Industrial relay sockets follow international standard dimensions and are interchangeable across brands if:

Pin count matches relay pole number

Corriente nominal (≥10A) meets load

Montaje (DIN-rail/screw) matches panel design

2. Terminal Type Selection

Conventional screw: PTF08A / PTF11A / PTF14A-suitable for low-vibration environments

Finger protection: PTFZ series-suitable for areas with frequent access

Push-In Plus: PTF-PU series-ideal for mass wiring, high vibration resistance

3. Modelos discontinuados

PTF08A-E / PTF14A-E are discontinued with limited stock.

Use PTFZ series as the preferred replacement.

> Nota: PTF series sockets are rated 10A/250VAC, dielectric strength AC 2000V, operating temp −25 °C to +55 °C, suitable for 0.5–2.5 mm² copper wires.
