External Mount Trapped Key Control Isolation Switch with Solenoid Controlled Key Release (SS-ISB4-SR)
The SS-ISB4-SR is used for isolating an electrical control circuit. The key is solenoid controlled and requires an unlock sign before the key can be turned to the OFF position, allowing it to be removed and transferred to the next stage in the Trapped Key System. The SS-ISB4-SR is housed in a robust 316 grade stainless steel enclosure and tested to IP69K for washdown environments.
