❓ Frequently Asked Questions

Q: What load can the EZC400H3320N protect at its rated 320 A?

A: The EZC400H3320N is rated to carry and protect circuits up to 320 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 320 A rating is used directly. Derate by 20% for ambient temperatures above 40°C.

Q: Is the EZC400H3320N 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: Can the EZC400H3320N 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 EZC400H3320N use — thermal-magnetic or electronic?

A: The EZC400H3320N uses a thermal-magnetic TMD trip unit — thermal bimetal for overload protection and electromagnetic mechanism for short-circuit. Compact, reliable, and maintenance-free for standard applications.

Q: What is the difference between an MCCB and a standard MCB — and why use the EZC400H3320N?

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 EZC400H3320N when the application specifically requires mccb characteristics.
