Explosion Proof Trapped Key Control Isolation Switch with Tongue Interlock (SS-TS-CB-EX)

Trapped Key Explosion Proof tongue switch interlocking with control isolation and certified ATEX Exd IIC T6 certified explosion proof contact block.

The SS-TS-CB-EX can be used to isolate the control circuitry and is designed to be mounted externally. Turning the key opens the safety contacts, turning the CONTROL CIRCUIT OFF, allowing the key and tongue to be removed. The SS-TS-CB-EX does not have a key present during normal operation and requires a key to be transferred to the access lock to gain entry. The SS-TS-CB-EX can be used at the gate as both a guard access interlock and/or control isolation switch.

The explosion proof contact block conforms to EN60079-0 and EN60079-1 for Zones 1, 2, 21, 22 environments (Gas and Dust). Adheres to the latest standard ISO13850.

Designed for applications where the potential for explosive atmospheres are present.

The stainless steel SS-TS-CB-EX Single Key Tongue Interlock with Explosion Proof Contact Block operates on the principle that when the key is “trapped” the actuator can be removed and is in the open position. When the key is in the “trapped” position the contacts switch to the auxiliary position in the contact block.

When the actuator is re-inserted and the “trapped” key removed the safety contacts in the contact block are then re-made.

Once the released key is in the Isolator Switch or Key Exchange System power can then be re-applied to the guarded area.

Manufactured in Stainless Steel 316 the SS-TS-CB-EX Tongue Interlock is suitable for SIP and CIP cleaning processes with high pressure hosing with detergents at high temperatures.
