3RT1481-6AF36

Description

Overview

The Siemens 3RT1481-6AF36 power contactor is designed for heavy-duty industrial operations requiring robust switching of high current circuits. With an AC-1 rating of 900 A at 690 V and a temperature capacity of 40 °C, this 3-pole contactor ensures exceptional reliability. Equipped with conventional auxiliary contacts (2 NO + 2 NC) and screw terminals, it offers flexible control solutions for both main and auxiliary circuits. Ideal for industrial motor controls, power distribution, and automation systems.

Benefits and Features

• High Current Rating: Ideal for switching large non-inductive or slightly inductive loads with its 900 A (AC-1) capacity.

• Flexible Control: Operates reliably across a universal control voltage range (110-127V AC / 100-110V DC), ensuring compatibility with various control panels.

• Integrated Auxiliary Contacts: Features a conventional drive and 2 NO + 2 NC auxiliary contacts built-in for seamless integration into interlocking and control circuits.

• Robust Terminal Design: Offers secure and efficient connections with a busbar connection for the main circuit and screw terminals for the control and auxiliary circuits.

• Space-Saving and Reliable: Designed for long-term reliability and efficient use of panel space, characteristic of the Siemens SIRIUS line.

Functions & Features

• Main Circuit: Busbar connection for efficient power distribution.

• Control Voltage: Uc: 110-127 V AC (50-60 Hz) or 100-110 V DC.

• Auxiliary Contacts: 2 normally open (NO) + 2 normally closed (NC) for additional control functions.

• Temperature Rating: Operates efficiently at 40 °C ambient temperature.

• Reliable Switching: High endurance and consistent operation for heavy industrial use.

Application

The 3RT1481-6AF36 is the go-to solution for switching high-current, resistive loads such as:

• Heating elements and furnaces

• Power factor correction systems

• Isolation of main distribution lines

• High-capacity lighting and signaling systems
