Product Description
The Siemens 3VA1112-6MH36-0AA0 is a 3-pole molded case circuit breaker (MCCB) from the 3VA1 series, designed for high-performance electrical systems that require robust starter protection. It offers enhanced short-circuit protection without overload protection, ideal for systems where motor starter protection is the primary requirement.
Key Features and Specifications:
- Frame Size: 160 A
- Class H: Icu = 70 kA at 415 V, ensuring a high level of fault current interruption to protect the system from severe electrical faults.
- Poles: 3-pole configuration, suitable for three-phase electrical systems.
- Rated Current (In): 125 A, ensuring reliable performance in systems with medium to high electrical loads.
Protection:
- Starter Protection (TM120M, AM): Specifically designed for motor starter applications, providing enhanced short-circuit protection while excluding overload protection, allowing for a focus on short-circuit events.
- Short-Circuit Protection (Ii): Adjustable between 7 to 16 times the rated current (Ii = 7…16 x In), offering highly responsive protection during short-circuit conditions, effectively safeguarding the system.
Connection Type:
- Terminal Connection: Provides a secure and reliable connection, ensuring ease of installation and maintenance.
Compliance & Environmental Considerations:
- RoHS Compliance: Compliant with the RoHS directive since 01.04.2014, ensuring it meets environmental safety standards by avoiding hazardous materials.
- REACH Compliance: No available SCIP number, but in compliance with the REACH regulations.
- WEEE Directive Compliance: Yes, it includes take-back obligations under WEEE (2012/19/EU).

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.
