Product description
TE Connectivity SCHRACK PT370024 – Power Relay, 3PDT, 24 V DC, 10 A, 240 V AC
TE Connectivity / SCHRACK PT370024 is a compact electromechanical power relay with a 24 V DC coil and three changeover contact sets (3PDT / 3 Form C). It is designed for general-purpose switching in control, automation and industrial electrical systems.
The relay provides a rated contact current of up to 10 A and a rated contact voltage of up to 240 V AC. The contacts use AgNi 90/10 contact material for reliable electrical switching performance in a wide range of control applications.
Key Features
- 3PDT / 3 Form C contact configuration.
- 24 V DC coil voltage.
- Rated contact current up to 10 A.
- Rated contact voltage up to 240 V AC.
- AgNi 90/10 contact material.
- Monostable, non-latching operation.
- 777 Ω coil resistance.
- 2.8 mm Quick Connect terminals.
- Integrated mechanical indicator.
- Manual test button for functional checking.
- White marking tabs for easier identification.
- Operating temperature range of -40 °C to +70 °C.
- Suitable for automation and process control applications.
3PDT Contact Configuration
3PDT (Three Pole Double Throw) means that the relay contains three independent changeover contact sets. Each set provides a common (COM), normally closed (NC) and normally open (NO) contact.
This configuration allows three separate circuits to be switched simultaneously using a single control signal. It is useful for switching multiple loads, changing signal paths or isolating several control circuits.
24 V DC Coil and 10 A Contacts
The PT370024 coil is designed for 24 V DC operation, making it suitable for 24 V industrial automation and control systems. The specified coil resistance is approximately 777 Ω.
The relay contacts are rated for up to 10 A at 240 V AC. The actual permissible load depends on the load type, voltage, current, switching frequency and other conditions specified in the manufacturer's technical documentation.
Mechanical Indicator and Manual Test
An integrated mechanical indicator provides a visual indication of the relay state. The relay also features a manual test element, allowing the switching function to be checked without applying the normal electrical control signal.
