EATON Z-SCH24/25-22 Installation Contactor 24V AC 2NO+2NC 25A 248850

In industrial and building control panels, switching resistive loads like heating or lighting circuits reliably requires a robust component that can handle frequent operations. The EATON Z-SCH24/25-22 installation contactor fulfils this role, providing a compact and durable solution for AC-1 duty.

Who is it for

This contactor is intended for electricians and panel builders who need to control resistive loads up to 25 A in distribution boards or control cabinets. It is suitable for applications such as electric heating, water heaters, and lighting systems where a 24 V AC coil is used for control.

Main features

• 4-pole contact configuration: 2 normally open (NO) and 2 normally closed (NC) contacts for flexible switching.
• Rated operational current of 25 A (AC-1) for handling significant resistive loads.
• 24 V AC coil voltage, compatible with standard control transformers.
• Compact 2-module (TE) width for DIN rail mounting, saving space in enclosures.
• High mechanical durability of 1,000,000 operations and electrical durability of 100,000 operations (AC-1).
• Screw terminals for secure and reliable wiring.

Tips

Ensure the control circuit provides a stable 24 V AC supply within the specified frequency range. When mounting, allow adequate ventilation around the contactor to maintain operation within the temperature limits. For resistive loads only; do not use for motor starting unless the load characteristics are within AC-1 ratings.
