Trapped Key Solenoid Isolation Switch Panel Mount

Trapped Key Power Isolation Switches with Solenoid Controlled Key Release (Stainless Steel)

The first stage of any Trapped Key System is to isolate either the switchgear or machinery (or both in complex operations). Traditionally, there are three common isolation methods used, which include mechanical, through the control system or through the power circuitry.

IDEM’s power isolation switches with solenoid controlled key release enforces a run-down period before allowing the key to be removed. This ensures that the machine is safely stopped before entering the hazardous area. This can be used to protect both machinery and personnel from harm.

The isolation key can be used to open an access lock with the same code or, if multiple access points are present, a key exchange unit can be used to release different coded keys. This will allow multiple gates to be open at the same time.

Panel Mount Trapped Key Power Isolation Switch with Solenoid Controlled Key Release (SS-ISP-SKR)

The SS-ISP-SKR is the first stage in the Trapped Key Process and is designed to mount directly to your panel. To turn the key, the solenoid requires a 24VDC signal to energise, allowing the key to be removed and transferred to the next stage in your Trapped Key System.

  • Body Material: 316 Grade Stainless Steel Barrel and Mounting Plate
  • Contacts: 4-Pole - Capable of Switching 690V at 25A or 40A

NOTE: Key sold separately. Optional auxiliary signal contact block (AUX-ISP) can be purchased to indicate the isolator status.

Panel Mount Trapped Key Power Isolation Switch with Solenoid Controlled Key Release IP65 (SS-ISP-SKR-WR)

The SS-ISP-SKR-WR is the first stage in the Trapped Key Process and is designed to mount directly to your panel. To turn the key, the solenoid requires a 24VDC signal to energise, allowing the key to be removed and transferred to the next stage in your Trapped Key System. SS-ISP-SKR-WR has been designed with a special seal, providing up to IP65 protection against dust and liquid ingress.

  • Body Material: 316 Grade Stainless Steel Barrel and Mounting Plate
  • Contacts: 4-Pole - Capable of Switching 690V at 25A or 40A

NOTE: Key sold separately. Optional auxiliary signal contact block (AUX-ISP) can be purchased to indicate the isolator status.
