Product Description

The 3VA2063-5KQ36-0AA0 is the 3-pole variant of the ETU860 family — the flagship trip unit in the SENTRON 3VA2 lineup. It delivers full LSIG protection with communication and measurement built in, making it the go-to choice when you need comprehensive system data alongside protection, without the extra width of a 4-pole frame.

Protection Functions

Overload (L): Ir = 25…63 A, I²t characteristic, delay tr = 0.5…25 s.
Short-time (S): Isd = 0.6…10 × In (38…630 A), tsd = 0.05…0.5 s.
Instantaneous (I): Ii = 1.5…12 × In (95…756 A).
Ground-Fault (G): Ig = 0.25…1 × In, tg = 0.05…0.8 s. Detected via residual current summation; switchable.
Communication & Measurement: Integrated — transmits operating data, alarms, and energy values via optional Modbus TCP, Modbus RTU, PROFINET, or PROFIBUS modules.
