Product Description
The Siemens 3VA1163-5MH36-0AA0 is a 3-pole Molded Case Circuit Breaker (MCCB) from the 3VA1 IEC series, engineered for robust starter protection in industrial and commercial electrical systems. Featuring a Frame 160 size and a breaking capacity class M (Icu = 55 kA @ 415 V), this device is designed to deliver reliable disconnection under high fault conditions while protecting downstream equipment.
This model is equipped with a TM120M trip unit (AM protection) optimized for starter applications. It provides short-circuit protection in the range of 7–16 × In but does not include overload protection, making it ideal for applications where motor starting and selective short-circuit protection are prioritized. The breaker comes with standard terminal connections for straightforward installation.

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.
