❓ Frequently Asked Questions

Q: Why is Curve B specified for the SK91277OOOO and what loads is it optimised for?

A: Curve B on the SK91277OOOO trips magnetically at 3–5× rated current, making it ideal for resistive loads such as incandescent lighting, electric heaters, and PTC elements. 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: How many padlocks can be applied to the SK91277OOOO for LOTO safety?

A: The SK91277OOOO 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 SK91277OOOO 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 SK91277OOOO switch-disconnector can therefore be used for operational switching, not just maintenance isolation.
