Simple Design. Increased Reliability.

Intelligent Protection and Control (iPAC) is a single generator, single utility, soft loading, closed transition transfer pair device. The iPAC utilizes the Schweitzer SEL 451* utility grade relay for all protection and control.

iPAC integrates the most trusted name in utility grade protection with digital generator paralleling control into a reliable and robust utility grade relay, backed by a 10-year warranty on controls and a 2-year warranty on power switchgear sections.** The iPAC eliminates the need for separate paralleling control, making the overall switchgear and controls package more cost effective.

The iPAC interface is simple and user friendly. Front panel membrane buttons make mode selection and breaker operation easy. Bright LED indicating lights clearly display system and breaker status. A scrolling back-lit LCD indicates real time utility and generator metering data, system, and protective relay status.

The simplicity of the control's design makes the iPAC suitable to interface with all major
generators and breakers. The iPAC controls as well as protects low and medium voltage transfer pairs. In medium voltage applications, the iPAC also provides overcurrent protection for the utility and generator sources, eliminating the need for expensive overcurrent relays.

Every iPAC comes standard with a modem for remote dial-in capability, providing you factory support when you need it most. The iPAC is also available with web-TOUCH monitoring capability and local HMI touch screens.
