❓ Frequently Asked Questions

Q: What load can the ST98065OOOO protect at its rated 400 A?

A: The ST98065OOOO is rated to carry and protect circuits up to 400 A continuously. For motor loads, ensure the full-load current (FLC) of the motor does not exceed this rating. For resistive loads (heaters, lighting), the 400 A rating is used directly. Derate by 20% for ambient temperatures above 40°C.

Q: Is the ST98065OOOO 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 ST98065OOOO coordination table for the specific contactor-overload-MCCB combination to confirm Type 1 or Type 2 coordination is achieved.

Q: Can the ST98065OOOO be motorised for remote switching and automation?

A: Yes. ST98065OOOO 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 trip unit type does the ST98065OOOO 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: What is the difference between an MCCB and a standard MCB — and why use the ST98065OOOO?

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 ST98065OOOO when the application specifically requires mccb characteristics.
