Product Positioning

The 3RT2024-1AP04 is a 230V AC 50Hz coil version with a coil holding apparent power of 65VA, a power factor of 0.82, and an operating voltage range of 0.8 to 1.1 times the rated value. Compared to the -1AP00, this model has four sets of instantaneous auxiliary contacts (2NO + 2NC) built-in, eliminating the need for external auxiliary contact sockets to complete multiple feedback and interlocking configurations. The body depth has been increased to 141mm accordingly. The main circuit remains AC-3 12A, 5.5kW/400V, suitable for automated control panels with limited space and requiring a large number of feedback signals.

Core Product Advantages and Features
230V AC 50Hz coil
It is compatible with the common 230V single-phase control power supply in Taiwan and can directly drive the coil without the need for a transformer.
2NO+2NC integrated molding
Four sets of auxiliary contacts are built into the main body, and a single component can complete multi-circuit feedback and interlocking, saving panel configuration space.
Coil parameters are well-defined and can be estimated.
It supports an apparent power of 65VA and a power factor of 0.82, which facilitates advance calculation of power supply capacity control.
Detachable auxiliary contact base design
It supports replaceable auxiliary switch modules, making future expansion or maintenance and replacement more convenient.
