FAQs
The 1SDA104958R1 is designed as a loose or configurable undervoltage release for Tmax XT5 and XT6. Follow the YU wiring instructions for wired or unwired configurations, ensure power is isolated, and mount the accessory onto the circuit-breaker chassis per the XT series guidelines. This approach minimizes wiring errors and speeds up field commissioning.
It supports 220-240 V AC and 220-250 V DC coils, with both AC and DC current types accepted. This dual compatibility reduces the need for multiple coil-specific parts and simplifies maintenance across mixed-power installations.
Ideal for Tmax XT panel installations, machine controls, and safety interlock systems where voltage dips could cause nuisance trips. Its XT5-XT6 compatibility makes it suitable for modernizing legacy panels and ensuring reliable shutdown during voltage fluctuations.
The accessory aligns with IEC 60947-2 and UL 489 standards, and carries RoHS and REACH declarations. CE declaration references ensure regulatory conformity across EU markets, reducing compliance risk in global deployments.
By reducing nuisance trips and ensuring accurate release timing, the accessory lowers downtime and extends motor/equipment life. Documentation and manuals support rapid installation, while cross-compatibility with XT5/XT6 simplifies inventory and spare-part economics.
