❓ Frequently Asked Questions

Q: Can the 33661 be motorised for remote switching and automation?

A: Yes. Schneider Electric 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 33661 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 33661 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 Schneider Electric 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 33661?

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 33661 when the application specifically requires mccb characteristics.
