The Allen Bradley 813S-V3-400V is a specialized voltage monitoring relay tailored for 3-phase applications. It maintains a rated voltage capacity that operates effectively between 380 and 415 volts AC. The frequency handling ranges from a minimum of 50 Hz up to a maximum of 400 Hz, making it suitable for various industrial settings.
Designed for efficiency, this relay operates on a self-powered control power type, minimizing the need for external energy sources. The contact configuration consists of two single-pole double-throw (SPDT) contacts, allowing it to manage multiple operational states efficiently.
In terms of environmental resilience, the 813S-V3-400V is rated IP20, thus providing moderate protection against physical contact and dust ingress. It features an adjustable time delay function, with a range from 1 to 6 seconds, enabling precise control over the timing of relay operations. The auto-reset behavior enhances convenience by automatically reverting to the default state after an activation, simplifying maintenance and troubleshooting processes.
