Product Positioning

The 3RT2026-1AP04 uses a common 230V AC 50Hz coil and upgrades the auxiliary contact configuration to 4 groups (2NO+2NC), doubling the number of usable contacts compared to the basic 1NO+1NC model. This makes it suitable for control panel designs that require multiple independent signals such as operation indication, fault feedback, and interlocking. The coil operating voltage range is 0.8~1.1 times the rated value, providing a certain tolerance for mains voltage fluctuations.

Core Product Advantages and Features

230V AC 50Hz coil

It corresponds to the standard mains power control voltage and can be used directly without the need for an additional transformer.

2NO+2NC four sets of auxiliary contacts

It can meet the needs of multiple feedback signals such as indication, alarm, and interlock in one go, without the need for external contact sockets.

0.8 to 1.1 times the operating voltage range

It has a certain tolerance for fluctuations in mains voltage, thus improving the stability of on-site operation.

AC-3 25A/11kW main circuit

The S0 housing is a standard rated, 3-pole design that meets the needs of most small and medium power motor applications.
