❓ Frequently Asked Questions
Q: Can the CM99805OOOO be motorised for remote switching and automation?
A: Yes. CM99805OOOO 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 CM99805OOOO 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 CM99805OOOO 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 CM99805OOOO coordination table for the specific contactor-overload-MCCB combination to confirm Type 1 or Type 2 coordination is achieved.
Q: What is the difference between an MCCB and a standard MCB — and why use the CM99805OOOO?
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 CM99805OOOO when the application specifically requires mccb characteristics.
