Emergency stop push-button collars
New protective collars designed to prevent inadvertent activation of emergency stop push-buttons
COOPER Crouse-Hinds, a leading manufacturer of explosion-protected electrical equipment, have launched a new range of protective collars for use on their Ex 41 series of explosion-protected push-button actuators.
The new metal protective collar attachments are suitable for use on the company’s GHG41, GHG43 and GHG44 series of emergency stop push-buttons and enclosures, which are designed for use in hazardous gas or dust environments.
Once fitted to the EX 41 push-button actuator, the collars prevent machine operators or plant personnel from inadvertently activating the emergency stop button, which if pushed, could lead to costly downtime of the plant process or could increase the risk of injury to plant personnel.
The collars are designed in such a way that inadvertent operation of the push-button is impossible. Two cut-outs in the collar allow easy, rapid release of the push-button. Depending on the particular design of the actuator, release is activated either by a key or manually by simply turning/pulling the button.
The collars are available in two colours: red or yellow, to suit all emergency or safety installation requirements, and are designed for use in ambient temperatures ranging from –55 degrees C to +55 degrees C.
They are also available as a retrofit kit, allowing them to be fitted quickly and easily to existing emergency stop push-buttons without drilling any holes, which could adversely affect the ingress protection (IP) rating of the enclosure or push-button panel.
