Description
The ABB KXTFYUC4 Accessory Undervoltage Release (MPN: KXTFYUC4) is an internal electrical accessory designed for automatic circuit breaker tripping upon voltage drop or power failure. Engineered for installation inside ABB SACE® Tmax XT5 and XT6 frame molded case circuit breakers (MCCBs), this undervoltage release (UVR) ensures that the circuit breaker opens automatically when the control voltage drops below specified threshold levels.
Operating across a dual voltage rating of 110 to 127 V AC and 110 to 125 V DC, the KXTFYUC4 features a fixed/plug-in mounting mechanism for quick and secure installation inside the breaker’s internal accessory pocket. It is an essential component for fail-safe power systems, emergency power off (EPO) circuits, and compliance with industrial safety interlock standards.
Key Features
- Automatic Fail-Safe Tripping: Automatically opens the circuit breaker when control voltage drops, preventing dangerous machine restart under low-voltage conditions.
- SACE® Tmax XT5 & XT6 Compatibility: Engineered specifically for fixed and plug-in installations in XT5 and XT6 frame circuit breakers.
- Dual AC/DC Voltage Rating: Operates reliably across 110–127 V AC and 110–125 V DC control circuits.
- Plug-In Mounting: Designed for easy plug-in installation into dedicated internal breaker slots for streamlined control wiring.
