Product Description
The Siemens 3VA1120-4EE46-0AA0 is a molded case circuit breaker (MCCB) designed for reliable protection in low to medium-power electrical systems. This 4-pole circuit breaker is particularly suited for systems that require protection for both phase and neutral conductors.
Key Features and Specifications:
- Frame Size: 160 A (IEC standard)
- Rated Current (In): 20 A
Breaking Capacity:
- Icu (Ultimate Breaking Capacity): 36 kA at 415 V, ensuring the breaker can safely interrupt high fault currents for medium-duty applications.
- Poles: 4-pole configuration, providing protection for three phases and an unprotected neutral conductor, suitable for balanced and unbalanced load systems.
Protection Features:
- Overload Protection (Ir): Adjustable between 14 A and 20 A, offering protection against sustained overcurrent situations that could damage connected equipment.
- Short-Circuit Protection (Ii): Set at 16x In, providing rapid response to short-circuit conditions to prevent further system damage.
- Protection Type: Line protection TM220 with ATFM (Advanced Trip Function Mechanism), allowing precise control and reliability in trip functions.
- Connection Type: Terminal connection, ensuring safe and straightforward installation.
Compliance & Product Lifecycle:
- Product Lifecycle Management (PLM): PM300 – Active Product, meaning this circuit breaker is actively sold and supported by Siemens.

Frequently Asked Questions
What is the full form of MCCB in Siemens?
The full form of MCCB is Molded Case Circuit Breaker. A Siemens MCCB is designed to handle high electrical currents, often up to 1000A, making it highly reliable for industrial and commercial applications. These breakers provide advanced protection against overloads and short circuits, ensuring the safety of large electrical systems.
What is the difference between a Molded Case Circuit Breaker (MCB) and an MCCB?
The main difference between an MCB (Miniature Circuit Breaker) and an MCCB (Molded Case Circuit Breaker) lies in their capacity and applications.
✅MCBs are generally used for low-power applications, with a short-circuit breaking capacity of up to 10–15 kA. They are best suited for residential and light commercial systems.
✅ MCCBs, on the other hand, are designed for medium to high-power applications, with a breaking capacity ranging from 15 kA up to 100 kA and current ratings up to 1000A. This makes them ideal for industrial environments where large electrical loads need reliable protection.
Which company circuit breaker is best?
✅ In 2025, the leading circuit breaker brands include Siemens, Schneider Electric, ABB, Eaton, and Legrand. Among them, Siemens MCCBs—especially the Sentron 3VA series—stand out for safety, durability, and advanced circuit protection in industrial and commercial applications.
What breakers work in a Siemens box?
Siemens QT, QP, QAF, and QPF breakers fit Siemens panels. However, not all breakers are interchangeable—e.g., a QT breaker cannot replace a QP breaker. Always check compatibility before replacing.
