Caterpillar® offers a broad range of transfer switch products that are positioned to support virtually any type of emergency power application from simple, single ATS installations to highly complex, multi-ATS/generator switchgear systems. Available in sizes ranging from 40 through 4000A, there is a Cat ATS to suit every project's needs.
Automatic Transfer Switches are an integral part of the Electric Power Group's strategy to be able to offer our customers maximum amount of Caterpillar products with Caterpillar generator sets. Today every standby generator set that is sold requires at least one ATS, and some cases require multiple units.
The new ATS product line offers three models of switches. The CTX series is designed for residential and light commercial applications. The CTG series for overall general applications with limited attachments, and the CTS series with a wide range of attachments and configurations. Overall features include:
- Mechanically held contactor
- Available in 2, 3, and 4 pole versions
- Rating range from 40 to 4000 Amps
- UL, IEC, and CSA listed
- NEMA 1, 3R, 4, 4X, and 12 enclosures
CTG Series & CTS Series Meets the requirements of NFPA 110, 99, and 70.
