The 3VA2063-5HL46-0AA0 is a 4-pole molded case circuit breaker from the Siemens SENTRON 3VA2 series (IEC Frame 100), designed for standard line and system protection in industrial low-voltage power distribution. Equipped with the ETU320 LI electronic trip unit, it provides essential overload (L) and instantaneous (I) protection—without short-time delay (Isd) or ground-fault (G) monitoring. This makes it a cost-effective choice for applications where selective coordination is not required and basic circuit protection suffices.

Core Protection & Functionality

• Overload protection (L): adjustable Ir = 25…63 A (I²t characteristic, tr = 0.5…17 s).
• Instantaneous short-circuit protection (I): adjustable Ii = 1.5…12 x In (95 A…756 A).
• Neutral conductor protection: adjustable OFF or 100% of In.
• No communication and no ground-fault monitoring—a straightforward solution for standard distribution panels.
• Solid-state overcurrent trip unit with integrated display for measured values.

Technical Specifications

• Rated Operating Voltage Ue: 690 V AC
• Breaking Capacity Icu: 55 kA @415 V (Class M)
• Rated Frequency: 50/60 Hz
• Power Loss: 1.8 W per pole (at rated current, hot operating state)
• Degree of Protection: IP40 (front face, with connected conductors)
• Net Weight: 2.914 kg

Installation & Application

• Mounting: Fixed on standard 35 mm DIN rail, terminal connection.
• Available mounting versions: fixed, plug-in, or withdrawable (this model via DIN rail fix).
• Typical Applications: Standard industrial main distribution boards, motor control centers, and generator panels where 4-pole switching with basic neutral protection is required, without the need for selective coordination or communication.
