Product Positioning

The 3RT2024-1BM40 is a 220V DC coil model, compatible with the 220V DC control power supply specifications commonly found in many older power panels or DC control systems. It can directly drive the coil without the need for additional step-down or rectifier circuits. The main circuit has a rated AC-3 voltage of 12A, 5.5kW/400V, and is equipped with 1NO+1NC auxiliary contacts. The unit weighs approximately 0.587 kg and is suitable for applications such as distribution boxes and motor control centers (MCCs) where existing 220V DC control power supplies must be directly utilized.

Core Product Advantages and Features
220V DC coil directly connected to existing power supply
No additional transformer or rectifier module is needed; it can be directly connected to a 220V DC control circuit, simplifying panel design.
1NO+1NC auxiliary contact
Provides one set of normally open and one set of normally closed feedback signals to meet basic interlocking and status monitoring needs.
S0 compact chassis mounting
With a width of 45mm and a height of 85mm, it shares the same electrical box installation space as other S0 models in the same series.
Screw terminal stable wiring
Both the main circuit and the control circuit use screw terminals, which reduces the risk of contact loosening during long-term operation.
