Siemens 3RT2015-1HB41 DC24V coil S00 3-pole 1NO auxiliary contact

Product Positioning

The 3RT2015-1HB41 is the smallest S00 frame 3-pole power contactor in the Siemens SIRIUS 3RT2 series. It uses a 24V DC operating coil and has a built-in normally open (1NO) auxiliary contact, which directly reflects the main contact's operating status for monitoring by the upper-level controller. In Siemens' official documentation, this model is explicitly listed as the official successor (Nachfollowyp/successor type) to the discontinued 3RT1015-1HB41. Its electrical dimensions, wiring method, and appearance are completely compatible, allowing for direct replacement of existing panels without redesigning wiring or mechanism holes. It is a common choice for replacing old equipment during maintenance. The main contact rated current is 7A, AC-3 operating power is 3kW/400V, and it can withstand up to 690V AC. It is suitable for direct starting and circuit switching of small single-phase or three-phase motors, as well as general industrial control applications such as pumps and fans.

Core Product Advantages and Features

Original factory official successor model

Official documents clearly indicate that 3RT2015-1HB41 is the designated successor to the discontinued 3RT1015-1HB41. Repair and replacement are based on this information, and there is no need to compare specifications and guess compatibility on your own.

24V DC standard coil

The operating voltage range is approximately 0.7 to 1.25 times the rated value, compatible with common 24V DC control power supplies and PLC output circuits, and the wiring is simple and intuitive.

1 set of normally open auxiliary contacts

It can instantly feedback the closing status of the main contact, which can be used as an operation indicator, interlock or counting signal, reducing the cost of installing additional signal components.

S00 minimum frame, screw terminals

Compact size, compatible with 0.5-4mm² wire locking terminals, facilitating dense configuration within distribution boxes and rapid on-site maintenance.
