Overview

The Hammond Power 2909C5 is a 2-coil autotransformer from the 2A-series, engineered for industrial motor starting applications. Operating at 480V, this unit is rated for up to 500 HP, providing essential voltage reduction for motor startup. This function is critical for minimizing inrush current and mitigating associated voltage dips on the power distribution system. By reducing the initial voltage supplied to the motor, the 2909C5 helps to decrease stress on motor windings, contributing to extended motor lifespan and improved operational stability. The 2A-series construction from Hammond Power ensures reliability in demanding industrial settings. Its specific application is to provide controlled voltage to large motors during their initial startup phase, a critical function for preventing system overload and ensuring smooth operation. The autotransformer configuration offers efficiency in voltage transformation for motor starting circuits. SKU: 2909C5. UNSPSC Code: 39121035. Country of Origin: US.

Frequently Asked Questions

What is the purpose of a motor starting autotransformer?

It limits the starting inrush current for larger motors or motors with connected loads, preventing disruption to the electrical system.

What types of loads are the 2A and 3A autotransformers designed for?

They are designed for Medium Duty service including applications for drive loads such as pumps, compressors, conveyers, and fans.

What is the insulation system temperature rating?

The insulation system for both two-coil and three-coil autotransformers has a rating of 220°C.

What standard taps are available on these autotransformers?

All units have taps available at 50%, 65%, and 80%.

What type of termination is provided?

Heavy solid copper lugs with holes are provided for reliable termination.

Are thermostats available as an option?

Yes, 1 or 2 optional thermostats are available for two-coil units, and 1, 2, or 3 for three-coil units.

What do the optional thermostats do?

Optional thermostats have normally closed contacts and signal when coil temperatures exceed safe operating conditions.

What voltages are available for the 2909C series (480V)?

The 2909C series is available for 480 Volts, with HP ratings from 20/25 up to 1600 HP.

What is the frequency rating for these autotransformers?

The autotransformers are rated for a frequency of 60 Hz.

What is the difference between 2A and 3A autotransformers?

The 2A is a three-phase, 2-coil unit for starters with 2 contacts in an open 'V' configuration, while the 3A is a three-phase, 3-coil unit for starters with 3 contacts in a three-phase 'Wye' configuration for balanced voltages.
