3RT2016-2BF41

Unlike most 24V DC versions in the same series, the 2BF41 has a coil voltage of 110V DC, making it suitable for applications with existing 110V DC control circuits. The main contacts and terminal specifications are consistent with the family.

Product Positioning

The 3RT2016-2BF41 is one of the few versions in its batch of selections with a coil voltage other than 24V—multiple electronic component distributors' specification sheets consistently indicate that its control coil voltage is 110V DC. This is particularly useful for applications where existing control circuits use 110V DC power (such as some older switchboards, marine or specific industrial control systems that retain the DC control voltage), allowing direct use of the existing power supply without the need for additional transformer/step-down modules. The main circuit specifications are the same as other members of the family: 3 normally open main contacts, S00 housing, AC-3 9A/4kW/400V, and one set of normally open (NO) auxiliary contacts, suitable for use as an operation indicator or linkage signal source. The terminals use a spring-clamp design, allowing for screwless wiring, balancing the special requirements of 110V DC control voltage with the convenience of standardized installation.

Core Product Advantages and Features

110V DC control coil

The coil voltage is 110V DC, suitable for applications with existing 110V DC control circuits, eliminating the need for an additional step-down transformer module.

1 set of normally open auxiliary contacts

It can be used as an operating status indicator or a signal source for linking the next control loop. The wiring logic is consistent with the 24V version.

Spring-loaded quick-connect terminals

Both the main circuit and auxiliary contacts are spring-clamp type, eliminating the need for screw fastening and resulting in high wiring efficiency.

Common main circuit specifications

The AC-3 9A/4kW/400V unit has the same housing as the S00 24V DC version in the same series, and spare parts and mounting hole layouts can be shared.

Recommend

3RT2016-2FB41

The F-shaped coil is 24V DC and has a built-in suppression diode. It has 3 sets of main normally open contacts and 1 set of normally open auxiliary contacts. The S00 housing is compact and lightweight, making it suitable for distribution boxes with limited space.

3RT2016-2BB44

Compared to versions in the same series that only have one set of auxiliary contacts, the 2BB44 provides four sets of auxiliary contacts (2NO + 2NC), which can simultaneously drive multiple interlocking or indicator circuits, reducing the cost of adding auxiliary contact sockets.
