❓ Frequently Asked Questions

Q: What instruments and meters are compatible with the 100/160 A CT ratio of the 3VA9988-0AB32?

A: The 100/160 A CT ratio means for every 100A in the primary (main) conductor, the secondary outputs 160 AA. Instruments connected to the secondary — ammeters, energy meters, protection relays — must be rated for 5A (or 1A where specified). Set the CT ratio in the connected meter/relay to 100/160 A so readings display the true primary current. Never open-circuit a CT secondary — this generates dangerous high voltages.

Q: What trip unit type does the 3VA9988-0AB32 use — thermal-magnetic or electronic?

A: Refer to the product label or datasheet for the exact trip unit specification. The trip unit determines adjustability and protection accuracy.

Q: Is the 3VA9988-0AB32 suitable for use as a motor branch circuit protector (Type E coordination)?

A: MCCBs used for motor branch circuit protection must be coordinated with the downstream overload relay for Type 2 coordination (no damage to contactor or relay on short-circuit). Verify the Siemens coordination table for the specific contactor-overload-MCCB combination to confirm Type 1 or Type 2 coordination is achieved.

Q: Can the 3VA9988-0AB32 be motorised for remote switching and automation?

A: Yes. Siemens MCCBs in this series support rotary handle adaptation and motorised operating mechanisms as accessories, enabling remote ON/OFF switching via PLC, SCADA, or BMS. Motorised MCCBs are used for automatic load management and remote trip in automated distribution systems.

Q: What is the difference between an MCCB and a standard MCB — and why use the 3VA9988-0AB32?

A: A standard MCB protects against overload and short-circuit only. An MCCB handles much higher fault levels and larger current ratings — MCCBs are rated up to 1600A with 25–200kA breaking capacity, compared to MCBs which are capped at typically 125A and 10kA. Choose the 3VA9988-0AB32 when the application specifically requires mccb characteristics.
