❓ Frequently Asked Questions

Q: Why is Curve D specified for the SK00348OOOO and what loads is it optimised for?

A: Curve D on the SK00348OOOO trips magnetically at 10–20× rated current, making it ideal for highly inductive loads with large inrush — transformers, large motors, welding machines. Using the wrong curve can cause nuisance tripping (too sensitive) or inadequate protection (not sensitive enough). Always match the curve to the load’s inrush characteristics.

Q: Can the SK00348OOOO 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 SK00348OOOO switch-disconnector can therefore be used for operational switching, not just maintenance isolation.

Q: How many padlocks can be applied to the SK00348OOOO for LOTO safety?

A: The SK00348OOOO 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.
