SG3A0015BK0C

Our Hammond HPS Sentinel^™ G general purpose distribution transformers are rated for 600 volts and below. They are generally used for supplying appliance, lighting, heating, motorized machine and power loads from electrical distribution systems.

This series is NEMA 3R, however, it is also a general purpose transformers with a bolt together enclosure. This offers you cost savings over fully welded steel enclosures if your application does not require it.

A quick overview of Hammond:

Control Transformers:

• HPS Imperator - molded for industrial machine tools
• HPS Spartan - open core and coil for light industrial applications
• HPS Fusion - general purpose enclosed transformer

Low voltage distribution transformers:

• HPS Sentinel G - general purpose (SG3)
• HPS Sentinel K - K-factor (SK3)
• HPS Sentinel H - harmonic mitigation (SH3)
• HPS Fortress - commercial applications
• HPS Titan and Titan N - hazardous locations
• HPS Sentinel Solar Duty - solar applications

Series Features Include:

Core & Coil Construction:

• Manufactured from quality non-aging, cold rolled, silicon steel laminations using state-of-the-art equipment
• Cores are precision cut to close tolerances which eliminates burrs and improves performance
• Core is coated to prevent the ingress of moisture
• Precision wound with copper or aluminum conductors that are electrically balanced to minimize axial forces during short-circuit conditions
• Robust interface between core & coils for better short circuit performance
• Conductor material: Copper or Aluminum
• Temperature rise: 150ºC typical (low rise options avail.)
• Insulation system: 220ºC
• HPS Sentinel G, K, and H product lines meet the latest energy efficiency standards outlined by DOE and NRCan offering significant energy savings to our customers and positive societal/environmental benefits.
• Standard Type 3R enclosure suitable for indoor or outdoor applications.

For our customers, higher efficiency translates into:

• Increased profitability due to lower operating costs
• Decreased cost of ownership over the lifetime of the transformer
• Less air conditioning cost due to lower heat emissions
• Expanded catalog product offer - up to 1000kVA
• Standard 10kV BIL rating provides increased reliability and protection against critical equipment failure (including voltage spikes and other line transients).
• Standard integral floor and wall mounting brackets up to 45kVA allow for faster installation.
• All units utilize a uniform 220°C insulation system with a 80°C, 115°C, or 150°C temperature rise.
• Industry leading design solutions, technology and materials continue the legacy of quality and reliability in all HPS products.
