The SS-ISP-SKR is a panel mounted trapped key operated isolation switch designed to turn off machine safety circuits.
The key is trapped when the main safety contacts are closed (machine able to run) and can only be released when the internal solenoid in the ISP-SKR is energised.
This then enables the key to be turned and released and the safety contacts opened. The key can then be used to release other devices in a trapped key system.
It can be used in conjunction with safety delay timers to allow a delay time before the solenoid is energised therefore allowing for any machine run down prior to releasing of the key.
Available with Stainless Steel 316 or die cast metal (mirror polished) mounting plate and barrel housing.
For all options please see catalogue page via download button.
In addition to the 4 pole main isolator contacts, all models of the isolation switch SS-ISP-SKR are supplied with:
RED lamp wired to indicate solenoid energized.
GREEN lamp for end user designation.
2NC 1NO monitoring contact block.
Solenoid energised to release key .
