Solid-state contactors approved for general use
Phoenix Contact's Contactron ELR 2+1 and ELR-3 series of solid-state contactors, which are designed for switching resistive and inductive loads have received UL 508 General Use approval, which allow them to be used in heating-load applications.
Phoenix Contact’s Contactron ELR 2+1 and ELR-3 series of solid-state contactors have received UL 508 General Use approval. This allows the contactors to be used in resistive and heating-load applications, in addition to across-the-line motor-starting applications. The Contactron ELR is designed for switching resistive and inductive loads. The Contactron ELR family is intended to replace electromechanical contactors in applications requiring frequent switching and maximum system availability. The Contactron ELR contactors feature a small form-factor, continuous duty rating, DIN rail-mounting installation, and low-voltage and line-voltage control configurations. These features increase the available space and add flexibility to control cabinet design without the wear that occurs in electromechanical contactors.
