What electrical load can it switch safely?
It is rated to carry and switch currents up to 16A for typical control and signalling circuits.
How is the unit installed onto a switch?
The contact employs a snap‑on mounting method that clips onto compatible switch mechanisms without separate fastening hardware.
Can it provide a test indication function?
The device offers a normally closed contact suitable for off‑state or fault indication
test‑indication arrangements depend on the host switch configuration.
Is it intended for multi‑pole configurations?
It is a single‑pole contact module intended for use where one NC auxiliary circuit is required.
Does it include mounting frames or adapters?
Mounting frames and additional adapters are offered separately for multi‑contact arrangements and specific switch types.
