Description

The Guardmaster Ex range of safety switches 440K-H11145 are specifically designed for potentially explosive atmospheres. They retain the safety features and operating principles of the conventional Guardmaster switches. 440K-H11145 incorporate a sealed flameproof contact block, making them suitable for use in European Zone 1 and Zone 2 environments. In the US and Canada, 440K-H11145 can be used in areas classified as Class 1, Division 2 in Groups A (acetylene), B (hydrogen), C (ethylene) and D (propane). All the Guardmaster Ex switches conform to the exacting standards required by the European harmonized standards.

These switches 440K-H11145 carry the classification EExd IIC T6 Baseefa. EEx equipment conforms to types of protection standardised by CENELEC (European standards), EN50014 and EN50018 respectively and BS5501 parts 1-V.

The d suffix indicates that the contact block in the switch 440K-H11145 is a flameproof enclosure and is designed to ensure that if an internal explosion occurs it will be contained with the enclosure. The designation II indicates use in surface industries and c refers to the group of gases for which the switches 440K-H11145 are suitable. The designation T represents the surface temperature classification of the switch. These switches 440K-H11145 have been tested with an ambient temperature of 60 as opposed to the normal test limit of only 40 , allowing them to be used in gases having a low flash point.

440K-H11145 should be noted that these groups refer to the explosion-proof qualities of the switches and not corrosion-resistance characteristics. Special precautions may be required to protect the vulnerable parts such as PVC-covered cables against attack by certain corrosive elements and physical damage.
