The 3VA2063-5HM36-0AA0 is a compact 3-pole molded case circuit breaker from the Siemens SENTRON 3VA2 series, designed for line and system protection in industrial low-voltage power distribution. Equipped with the ETU330 LIG electronic trip unit, it offers a powerful combination of overload (L), instantaneous short-circuit (I), and ground-fault (G) protection—ideally suited for applications where earth-fault monitoring is essential but communication functions are not required.

Core Protection & Control

• Overload protection (L): adjustable Ir = 25…63 A, I²t characteristic with tr = 0.5…17 s.
• Instantaneous short-circuit protection (I): adjustable Ii = 1.5…12 x In.
• Ground-fault protection (G): adjustable pickup Ig = 0.25…1 x In, with selectable time delay tg = 0.1 s or 0.3 s. Detection by residual current summation across all three phases.
• No communication function and no additional measurement—a cost-optimized solution for standard system protection.
