❓ Frequently Asked Questions

Q: What is the significance of the 200 A rating on the CK90821OOOO?

A: The 200 A rating is the device’s maximum continuous current carrying capacity under specified conditions (typically 40°C ambient). For circuit design, use 80% of this value as the design current to allow for derating due to grouping, temperature, and future load growth.

Q: How many padlocks can be applied to the CK90821OOOO for LOTO safety?

A: The CK90821OOOO switch disconnector supports up to 3 simultaneous padlocks on the OFF-position locking facility. This allows multiple contractors or maintenance teams to each apply their own padlock, ensuring the circuit cannot be re-energised until all teams have removed their lock — a critical requirement for multi-contractor LOTO procedures.

Q: Can the CK90821OOOO make and break load current, or is it for isolation only?

A: This is a switch-disconnector (not a pure isolator), meaning it is rated to make and break load currents up to its rated current under AC-22A or AC-23A utilisation categories. Pure isolators must only be operated on de-energised circuits. The CK90821OOOO switch-disconnector can therefore be used for operational switching, not just maintenance isolation.
