❓ Frequently Asked Questions

Q: What does the 70 kA breaking capacity on the CM96026OOOOAG mean in practice?

A: Breaking capacity (70 kA) is the maximum prospective short-circuit current the CM96026OOOOAG can safely interrupt without damage. Before installing, verify that the prospective fault level at the installation point does not exceed 70 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 CM96026OOOOAG 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 CM96026OOOOAG coordination table for the specific contactor-overload-MCCB combination to confirm Type 1 or Type 2 coordination is achieved.

Q: Can the CM96026OOOOAG be motorised for remote switching and automation?

A: Yes. CM96026OOOOAG 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 CM96026OOOOAG 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: After a short-circuit trip on the CM96026OOOOAG, can it be reset and reused immediately?

A: After a short-circuit trip, do not immediately reset the CM96026OOOOAG. First, identify and clear the fault. Then inspect the device — if there is visible arc damage, melted insulation, or the handle does not reset smoothly, the device must be replaced. The 70 kA rated breaking capacity is not unlimited — it is the maximum fault current the device can interrupt safely for a defined number of operations (typically 1–3 at full Icu rating). After any significant fault, factor replacement into your maintenance budget.
