Product Positioning

The 3RT2015-2JB41 is a model of the SIRIUS 3RT2015 coupling contactor in the "J" rail series, which has been clearly verified by online retailers. It features a 24V DC coil, a built-in fixed (non-external) surge suppression diode, spring-loaded terminals, and a factory-installed set of normally open (1NO) auxiliary contacts, making it suitable as an intermediate feedback element for "conducted" signals. Compared to the 2JB42, which is also a J rail model but normally closed, both have the same coil and terminal construction, only the auxiliary contacts are reversed, allowing for flexible selection based on the site's interlocking logic. The measured net weight is approximately 0.315 kg, and the main circuit maintains the S00 frame AC-3 rated 7A, 400V 3kW level, making it suitable for signal isolation and amplification in space-constrained control boxes.

Core Product Advantages and Features

Built-in fixed diode

The diode is integrated into the coil body and cannot be replaced like the K-rail type. The structure is more compact and suitable for long-term stable operation and applications where on-site parts replacement is not required.

Spring terminal +1 NO contact

The spring-loaded terminal comes with a factory-fixed set of normally open auxiliary contacts, suitable for use as a start confirmation or signal feedback.

Actual weight can be verified.

According to e-commerce data, the net weight is approximately 0.315 kg, which helps in estimating the installation space required for the control box and the overall shipping weight.

S00 frame coupling contactor positioning

Continuing its role as a small frame and coupling contactor, it is suitable for isolation and amplification applications of small signal output from PLCs.
