Construction

Aluminium alloy used to manufacture HTB1A series of terminal boxes has been selected to grant the maximum protection against the highly corrosive agents and harsh environment in hazardous areas. HTB1A enclosures have following features:

body and cover are made of an aluminium alloy with very low (less than 0,1%) content of copper to provide the maximum corrosion protection

made of copper-free aluminium, enclosures guarantee high resistance to sea water corrosion and can withstand the harshest temperatures

enclosure can house Ex e and Ex i terminals. Maximum number of terminals depends on terminals’ section, enclosure operating temperature and required temperature class

cover screws are made of stainless steel AISI 316L.

cover gasket is made of silicone

internal fixing screws are made of stainless steel AISI 316L

Application

HTB1A series of terminal box enclosures can be used for the following applications:

control stations

instrument housings

switches and changeovers

terminal boxes

battery containers

emergency call units

circuit breakers

lighting controls

electrical housings

HTB1A series terminal boxes can accommodate terminals for wires with a maximum diameter of 16mm2 including terminals for intrinsically safe circuits. They are ideal for offshore and onshore applications where harsh and explosive atmosphere is present.
