Polar Zone: Components and systems for extreme temperatures - 2

2 Our customers safety in their day-to-day work is the main focus of our business. The company has been working towards this for over 80 years and has had a major impact in the sector of explosion protection. Development of explosion protected, electrical control devices and control units was speeded up consistently and successfully since 1926. This resulted in pioneering new developments and innovative products. R.STAHL specialists have been working actively for many years now in national and international committees to define new standards and ever better safety regulations. R.STAHL...

3 The working temperature range for explosion protected electrical apparatus defined in IEC 60079, Part 0:General Requirements, extends from 20ְC to +40C. If the type plate contains no other information on ambient temperature, it can be assumed that the apparatus will operate reliably within this temperature range. Frequently however, products need to be used under ambient conditions where prevailing temperatures are either far higher than +40аC or are well below 20ְC. This is case in many regions of the world in the winter months where temperatures of 55ְC are no rarity. In respect of...

Restrictions and special aspects that are important for operation at low temperatures: Restricted functionality > 1 > Moving parts such as the actuators of switching elements may no longer be operable after thawing followed by freezing. > Various types of lamp, such as low-pressure gas-discharge lamps, cannot be ignited or can be ignited only with difficulty at temperatures below 0C and suffer a substantial loss in light output. > The accuracy of many measuring instruments drops with decreasing temperature. > Protective circuit breakers with bimetallic trip mechanism change their trip...

Installation, maintenance and repair work should not be carried out at low temperatures in order to avoid destruction of the seals when enclosures are opened. > Special seals that must be stated when ordering the product can be used to seal moving parts. Cables and leads > Many types of cable are unsuitable or only restrictedly suitable for use at low temperatures. > The permitted bending radius must be complied with, depending on temperature. > 5 Strip lamps > The reduced light output of strip...
