YOSHINE Star-Delta Delayed Start Time Relay
The YX5520 Star-Delta Delayed Start Time Relay features a DPDT output configuration with an on delay function and a preset timing range of 30 to 60 seconds. It is intended for star-delta motor starting systems that require a defined delay period before switching from star to delta operation.
This relay enables timed activation after power is applied, supporting controlled startup procedures in motor-driven equipment. The focused timing range aligns with common star-delta transition requirements, making it suitable for applications where the delay window is standardized.
Designed for panel mounting, the YX5520 offers straightforward installation and clear wiring identification. The time adjustment mechanism allows accurate configuration within the specified range, helping maintain coordination between control components such as contactors and protective devices.
It is commonly applied in industrial machinery, ventilation systems, and general automation setups where structured motor startup timing is required. Within a star-delta configuration, the YX5520 supports controlled energizing sequences to maintain system consistency.
