Phase sequence protection relay

phase lossthree-phasefor electric motors

Product overview
The Simpedil Phase Control and Sequence Relay is a compact electromechanical/electronic device designed to verify phase sequence and detect phase loss for three-phase motors and equipment. It is used to ensure correct motor rotation at start-up and to protect equipment from damage due to missing or incorrect phases.

Key features

• Phase sequence monitoring: Verifies correct phase order to ensure motors start in the intended rotation direction and to prevent mechanical issues related to reverse rotation.
• Phase loss detection during start-up: Checks presence of all phases at motor start to avoid improper starts and associated operational failures.
• Continuous phase loss monitoring: Detects phase interruptions during operation to protect motors against overheating and damage, supporting reliable continuous operation.
