❓ Frequently Asked Questions
Q: What is the significance of the 63 A rating on the 3LD2504-0TK51?
A: The 63 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 3LD2504-0TK51 for LOTO safety?
A: The Siemens 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 3LD2504-0TK51 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 Siemens switch-disconnector can therefore be used for operational switching, not just maintenance isolation.
