Siemens 3MT8065-1AP04 Contactor AC-3, 65A/30kW, 400V, 2NO2NC, 230 VAC, 50 Hz, 3-pole, size S2 Original Brand New

Overview

The Siemens 3MT8065-1AP04 is a robust and reliable 3-pole AC-3 contactor, engineered for demanding industrial control applications. Designed for high switching frequency and heavy-duty operation, this size S2 contactor is ideal for controlling motors and resistive loads up to 65 Amperes or 30 kilowatts at 400 Volts. Its compact design, coupled with versatile 2NO+2NC auxiliary contacts, provides exceptional flexibility for a wide range of circuit configurations. The convenient screw terminal connections ensure secure and straightforward installation, making it a preferred choice for professionals seeking efficiency and durability in their electrical systems.

Function

The primary function of the Siemens 3MT8065-1AP04 contactor is to safely and efficiently switch high-power electrical circuits. When its 230 VAC, 50 Hz coil is energized, the contactor’s main contacts close, allowing power to flow to the connected load (e.g., a 3-phase motor). When the coil is de-energized, the contacts open, interrupting the power supply. The integrated 2 Normally Open (NO) and 2 Normally Closed (NC) auxiliary contacts provide additional control and signaling capabilities, enabling interlocking, status indication, and integration into complex automation systems. This contactor is specifically rated for AC-3 utilization category, making it perfectly suited for general motor control applications where starting current peaks are involved.
