The 3VA2063-5HN36-0AA0 is a cost-optimized 3-pole molded case circuit breaker from the Siemens SENTRON 3VA2 series. Designed for line and system protection in low-voltage power distribution, it integrates the reliable ETU350 electronic trip unit with essential LSI protection.

Core Protection & Application

• Overload Protection (L): Adjustable Ir 25-63A with I²t characteristic (tr 0.5-17s).
• Short-Time Short-Circuit (S): Adjustable Isd 1.5-10 x Ir.
• Instantaneous Protection (I): Fixed Ii = 12 x In (756A).
• No communication and no ground-fault monitoring, making it a price-competitive choice for standard secondary distribution where these digital features are not required.
