The Siemens 5TT3421 voltage monitoring relay (T5570 series) provides dependable mains supervision for AC 230/400 V systems in switchboards, control panels, and OEM equipment. It helps protect critical loads by reacting to undervoltage conditions and supporting coordinated control logic in professional electrical installations.

With defined 0.85/0.95 Un thresholds for dropout and reset, the device delivers stable hysteresis and clean switching via a 1 CO (SPDT) contact for signaling, interlocking, or load-shedding functions. A transparent cap safeguards the settings against accidental adjustment while allowing quick visual checks during commissioning and maintenance.

Ideal for low-voltage distribution and control applications, the 5TT3421 integrates smoothly into new builds and retrofits, supporting reliable operation and compliance while being backed by a 1-year warranty for added assurance.
