Siemens 3MT8170-1AV07 Power Contactor 170A, 90kW, 400V, 400V AC Coil, S8 Size Original Brand New

Overview

Siemens 3MT8170-1AV07 Power Contactor is a high-performance, heavy-duty switching device expertly engineered for demanding industrial motor control applications. As a cornerstone component of the globally recognized Siemens SIRIUS 3RT series, this 3-pole contactor is built to deliver exceptional reliability, superior performance, and an extended operational lifespan, even in the most challenging industrial environments across Indonesia and beyond.

Key Features & Functions:

• Robust Motor Switching (AC-3 Duty): Designed specifically for the AC-3 utilization category, the Siemens 3MT8170-1AV07 Contactor is perfectly suited for efficiently switching large inductive loads, particularly three-phase asynchronous motors. Its primary function is to establish and interrupt the main current path to the motor, enabling precise control over its operation.
• High Current & Power Capacity: It boasts an impressive current rating of 170 Amperes and can reliably manage motor power up to 90 kW at 400V. This substantial capacity makes it an ideal solution for critical, high-power motor switching tasks across various heavy industrial sectors, including large pumps, ventilation systems, compressors, and various manufacturing machinery.
• Direct 400V AC Coil Operation: This Siemens 3MT8170-1AV07 Contactor operates with a 400V AC control coil at 50Hz. This direct operating voltage coil simplifies control circuitry by often allowing direct connection to the main supply (in systems where 400V AC is the control voltage), reducing the need for additional transformers in some setups.
• Compact & Modular Design (Size S8): Its size S8 designation indicates a powerful yet relatively compact unit within the modular SIRIUS system. This allows for efficient use of space within control cabinets while maintaining robust performance. The modularity also ensures compatibility with other SIRIUS components.
• Secure Screw Terminal Connections: Equipped with reliable screw terminal connections for both main and auxiliary circuits, the contactor ensures robust and long-lasting electrical contact. This simplifies wiring, reduces installation time, and enhances overall system integrity and safety by minimizing the risk of loose connections or failures, crucial for high-current applications.
• Extensive Auxiliary Contacts (4NO4NC): For enhanced control flexibility and comprehensive signaling capabilities, the 3MT8170-1AV07 is equipped with an extensive set of 4 normally open (NO) and 4 normally closed (NC) auxiliary contacts. These integrated contacts provide unparalleled options for complex control logic, precise interlocking with other components, real-time status monitoring, and simplified diagnostic capabilities within sophisticated automation architectures, reducing the need for external auxiliary blocks.
