3RT2016-2XF41-0LA2

The 3RT2016-2XF41-0LA2 belongs to the Siemens SIRIUS 3RT2016 series. The main contacts are AC-3 rated at 9A, 4kW/400V. The coil code X indicates an electronic wide-range DC coil (the same series covers 72~125V). It has a built-in surge suppression circuit and is equipped with spring terminals and one set of normally open auxiliary contacts.

Product Positioning

The 3RT2016-2XF41-0LA2 uses an electronic wide-range coil with the code 'X' from the SIRIUS series. Unlike traditional electromagnetic coils, the X-type coil has a built-in electronic drive circuit, allowing for stable holding over a wider DC voltage range. According to official data for the 3RT2017-2XF42-0LA2 in the same coding family, the DC version supports 72~125V, with an operating range of 0.7~1.25 times the rated voltage. It also features built-in surge suppression components to reduce interference to surrounding control circuits during coil de-energization. The main contacts maintain the 3RT2016 series AC-3 9A, 4kW/400V specifications, with spring-clamp terminals. The auxiliary contacts are, according to the order number convention, one set of normally open (NO) contacts, which is optional with the normally closed version of the same family, '42'.

Core Product Advantages and Features

Electronic wide-range coil design

The coil, designated X, has a built-in electronic drive circuit, enabling it to stably hold the coil within a wide DC voltage range and is more adaptable to voltage fluctuations than traditional electromagnetic coils.

Built-in surge suppression circuit

The coil circuit integrates surge protection components, which can reduce interference to surrounding PLCs or electronic control components when the coil is de-energized.

Spring-type terminal wiring

Both the main circuit and the control circuit use spring clip terminals, eliminating the need for screw fastening, making them suitable for applications with extensive wiring or requiring frequent maintenance.

AC-3 9A/4kW main contacts

The main contact specifications are the same as the 3RT2016 series, with a rated current of 9A and a power of 4kW at 400V, suitable for direct start control of small three-phase motors.

3RT2016-4BB41

The 3RT2016-4BB41 belongs to the Siemens SIRIUS 3RT2016 series. The main contacts are rated AC-3, 9A, 4kW/400V, and the 24V DC coil is equipped with one set of normally open auxiliary contacts. According to the original catalog, the 8th digit of the order number '4' indicates that the main circuit adopts a ring crimp terminal design, which is suitable for crimp wiring.

3RT2016-2VB42

The Siemens 3RT2016-2VB42 is a SIRIUS contactor with an S00 housing. It can stably engage with a coil voltage of 0.85 to 1.85 times the rated value. It has a built-in diode to suppress back EMF and is equipped with a set of normally closed auxiliary contacts for easy signal feedback configuration.

3RT2016-2VB41

Belonging to the same V-shaped coil family as the 2VB42, the 2VB41 differs in that the auxiliary contacts are changed to one set of normally open (NO). The other wide-range coil characteristics, housing size and terminal type are exactly the same, making it convenient to select the corresponding version according to the control circuit logic.
