FAQ

Question?
What is the difference between this STI switch disconnector and a standard iC60 circuit breaker?

Answer
While they look similar, the STI A9V11563 is a switch disconnector (isolator) designed for safely de-energizing a circuit for maintenance. It does not provide overcurrent or short-circuit protection like an iC60 circuit breaker. It must be used in conjunction with a protective device like a fuse or circuit breaker upstream.

Question?
Can this A9V11563 be used in a DC circuit?

Answer
No, this switch disconnector is specifically rated for 500V AC (Alternating Current) at 50/60Hz. Using it in a DC (Direct Current) circuit is not recommended and would violate its certification and safety ratings, as DC arcs are more difficult to extinguish.

Question?
What is the breaking capacity (Icn) of this device?

Answer
As a switch disconnector, its primary rating is not the breaking capacity (Icn) like a circuit breaker. Its relevant ratings are the rated operational current (Ie = 25A) and its ability to withstand short-circuits when protected by an upstream device. It's designed to make, carry, and break currents under normal circuit conditions.
