Features of the Klippon® STB Range enclosure range:

• Available in stainless steel or in steel sheet
• Higher temperature resistant seals than the standard (extended temperature range of -60 °C to +100 °C / 120 °C, on request)
• Flexible options when mounting the internal rail
• The gasket is protected against compression; this ensures that a permanent and secure seal is maintained.
• Earth studs in the lid and in the enclosure base
• Lasered welding seams offer-improved quality
• Delivered with welded mounting feet to ensure a sturdy enclosure installation

The Klippon® POK range is based on a high-quality glass fibre-reinforced polyester enclosure which represents an economical solution for electrical connections. The enclosures are ideal wherever corrosion resistance, impact resistance and a high IP protection class are required.

Features of the Klippon® POK range enclosure range:

• Manufactured from glass fibre reinforced polyester
• Available in 17 sizes
• Two standard finishes (colours) Grey, similar to RAL 7001 (industrial use) Black, similar to RAL 9011 (harsh environments, Ex)
• Captive lid fixing screws are stainless steel
• Fixing holes are located outside of the lid sealing area to ensure high ingress protection of P66
• Threaded holes for internal component mounting
• Silicone sealing for extreme temperature environments
• Impact resistance up to 10 Joules
• Approved to the latest international standards, including EN62208 and IEC EN 60079

Control Stations

Safety switches ensure that machines and installations are disconnected from the energy supply during maintenance and repair work. Isolator switches, circuit breakers and "break glass" call points are designed to prevent operation in explosive atmospheres during connect and disconnect operation of power loads.

D Series aluminium control stations provide safe control of equipment in classified hazardous locations. They are available with 1, 2 or 3 functions, including options for a variety of push buttons, time delayed push buttons, pilot lights, ammeters and limit switches. Ideal for the control of electrical equipment at power plants, chemical and petrochemical plants, petroleum refineries, pulp and paper processing plants and various industrial applications. 

Stainless steel control stations and switches are ideal for use in hazardous locations and washdown areas. A variety of push buttons and selector switches are available for use in conjunction with contactors or magnetic starters for remote control of motors. They provide circuit control and/or selection. Pilot lights are available to provide visual assurance that an electrical function is being performed at a remote or local location.

Appleton™ flameproof ATX™ SWD Series

SWD Series 20, 32, 63, 100, 125, 160 and 250 Amp isolator switches, circuit breakers and "break glass" call points are designed to prevent operation in explosive atmospheres during connect and disconnect operation of power loads. They are ideal for use in hazardous areas where ignitable vapours, gases or highly combustible dusts are present.

Appleton™ flameproof ATX™ MS Series 

 

SWE Series 16 and 20 Amp switches, circuit breakers, and "break glass" call points are designed to prevent operation in explosive atmospheres during connect and disconnect operation of lighting and light power loads. They are ideal for use in hazardous areas where ignitable vapours, gases or highly combustible dusts are present.

Distribution Boards

The AP Haslam Workshop can create bespoke Distribution boards for Atex environments to suit your needs, dividing power feed into subsidiary circuits, while providing a protective fuse or circuit breaker for each circuit in a common enclosure. Here are some examples built to customer specifications. 

Aluminium Alloy Enclosure-Ex d Dual DOL

Using an Aluminium alloy enclosure (632(h) x 432(w) x 271(d) mm) EJB-5B Exd Enclosure ATEX certified IIB T4/T6 (H2 Available on request), Dual 3 Phase 25amp 400V, 50Hz, N, PE Direct On Line Start Panel c/w 24v AC controls 

Our client was installing Wi-Fi access points and required Atex enclosures for them.
The access points had to have remote antennae so the enclosures required 3 no cable gland entries (1x cat 6 cable & 2x antenna cables)
The access point dimensions (without mounting bracket):
(W x L x H)  
8.7 x 8.7 x 1.84 in.
22.1 x 22.1 x 4.7 cm
Weight 1.9 lbs. (0.86 kg)
Our customer also required space inside the enclosure for a RJ 45 outlet.

Switch Disconnects

Safety switches ensure that the machines and installations are disconnected from the energy supply during maintenance and repair work. The safety switches can be used with both conventional drives and drives controlled by frequency converters. They are ideal for use in Hazardous areas where ignitable vapours , gases or combustible dusts are present.

20, 32, 63, 100, 125, 160 and 250 Amp isolator switches, circuit breakers and "break glass" call points are designed to prevent operation in explosive atmospheres during connect and disconnect operation of power loads.

16 and 20 Amp switches, circuit breakers, and "break glass" call points are designed to prevent operation in explosive atmospheres during connect and disconnect operation of lighting and light power loads, ideal for use in hazardous areas. 

16 and 32 Amp switches, circuit breakers and "break glass" call points are designed to prevent operation in explosive atmospheres during connect and disconnect operation of lighting and light power loads, ideal for use in hazardous areas where ignitable vapours, gases or highly combustible dusts are present.
