❓ Frequently Asked Questions

Q: What load can the CM98065OOMO protect at its rated 160 A?

A: The CM98065OOMO is rated to carry and protect circuits up to 160 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 160 A rating is used directly. Derate by 20% for ambient temperatures above 40°C.

Q: What does the 36 kA breaking capacity on the CM98065OOMO mean in practice?

A: Breaking capacity (36 kA) is the maximum prospective short-circuit current the CM98065OOMO can safely interrupt without damage. Before installing, verify that the prospective fault level at the installation point does not exceed 36 kA — this is checked using a fault level calculation or from the upstream transformer impedance data. Installing a breaker with insufficient breaking capacity is a serious safety violation.

Q: Is the CM98065OOMO 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 CM98065OOMO coordination table for the specific contactor-overload-MCCB combination to confirm Type 1 or Type 2 coordination is achieved.

Q: Can the CM98065OOMO be motorised for remote switching and automation?

A: Yes. CM98065OOMO 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 CM98065OOMO use — thermal-magnetic or electronic?

A: The CM98065OOMO 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.
