Product description

The Siemens 3RT2018-2FB41 is a 3-pole power contactor for AC-3e/AC-3 use, rated at 16A and 7.5 kW at 400V. It operates with a 24V DC coil and features an integrated diode for reduced coil consumption and faster switching. This model includes one normally open (NO) auxiliary contact and utilizes spring-loaded terminals in size S00.

This contactor is ideal for motor control applications where a DC coil with an integrated suppression diode is required, offering benefits such as lower power dissipation and protection against inductive voltage kicks.

Stanlo Automation, a veteran-owned business, offers the Siemens 3RT2018-2FB41. We specialize in providing quality surplus industrial parts to help you maintain and upgrade your automation systems efficiently.

Frequently asked questions

What is the advantage of the integrated diode in the Siemens 3RT2018-2FB41?

The integrated diode in the 3RT2018-2FB41 acts as a freewheeling diode, suppressing voltage spikes when the coil is de-energized. It also reduces residual magnetism and allows for faster switching cycles compared to contactors without suppression.
