Reflected Wave Protection Reduces Peak Voltages Protects Motor Insulation Designed for Allen-Bradley Drives Type 4X Enclosure Class I, Division 2 Rated

Product description

The Allen Bradley 1204-TFB2 is a motor terminator designed to protect AC motors and drives from reflected wave phenomenon, which can occur with long motor leads. It reduces peak voltages and protects motor insulation from corona and insulation failure.

This terminator is ideal for use with Allen-Bradley adjustable frequency AC drives to enhance motor protection. It can be installed with minimal concern over motor-cable surge impedance mismatches and does not significantly impact waveform quality or motor torque.

Stanlo Automation, a veteran-owned distributor of industrial automation parts, offers the 1204-TFB2. We provide reliable surplus components to ensure the longevity and performance of your critical equipment.
