Product Positioning

The 3RT2015-1BB41-1AA0 belongs to the SIRIUS 3RT2015 S00 frame, with 3-pole main contacts (3NO), AC-3 rated 7A, corresponding to approximately 3kW at 400V. The coil is 24V DC, and the terminals are screw-type. E-commerce information clearly indicates that it must be installed "upright," so special attention should be paid to the orientation when designing the distribution box. Only one set of normally open (1NO) auxiliary contacts is configured, which is complementary to the 1NC of the 1BB42, allowing for selection of start-up or power-off feedback logic depending on the interlocking circuit requirements. The unit weight, according to e-commerce measurements, is approximately 0.299 kg. The outer packaging dimensions are approximately 50×61.5×77.5 mm for estimating shipping volume. For the 1AA0, no publicly available specifications were found; therefore, it is described as the basic model.

Core Product Advantages and Features

24V DC coil

The coil voltage is 24V DC, and the operating voltage range is approximately 0.7 to 1.25 times the rated value, making it compatible with most 24V control power supplies.

Designated upright installation

The product documentation clearly indicates that it must be installed in an upright position. When arranging the control box configuration, attention should be paid to the orientation to ensure that the operating characteristics are normal.

1NO auxiliary contact

It has a built-in set of normally open auxiliary contacts, which are suitable as a feedback signal source for the "started" state or a self-holding circuit.

Actual weight and dimensions are available.

Each unit weighs approximately 299 grams and has packaging dimensions of approximately 50×61.5×77.5 mm, making it easy to estimate installation space and logistics costs.
