Siemens PT370024 Plug-In Relay

Siemens PT370024 is a SIRIUS plug-in relay with a 24 V DC coil and three Form-C (changeover) contacts, designed to switch up to 10 A at 250 VAC when used with LZS plug-in bases. It is 22.5 mm wide in the LZS socket family, enabling compact, modular installation alongside other Siemens relays and logic modules. The relay is intended for switching small loads in control panels and can be actuated reliably by a low-voltage 24 V DC control circuit; pairing it with the LZS plug-in base PT78730 in the SIRIUS LZX family provides galvanic isolation and convenient, replaceable modules for multi-circuit control from a single unit. This configuration supports multiple isolated circuits from a single module and is suitable for applications where independent switching of three loads is required, such as lighting, signaling, or small actuators, all within the typical 10 A, 250 VAC rating and the compact 22.5 mm footprint.
