Key Selection Considerations

1. Contact Quantity: Choose 1-set (1X21) or 2-set (2X21) PDT according to control loops.
2. Type de connexion: Push-in for mass installation; screw connection for vibration environments.
3. Wire Gauge: Confirm compatibility with 24-16AWG (0.14-1.5mm²); derate to 1.0mm² for twin-wire connection.
4. Expansion Requirements: Select models supporting plug-in modules if indicator or surge suppression is needed.
5. Brand Compatibility: Prefer same-brand sockets when using relays from Schneider, Omron and other brands.
