Characteristics of enclosures for aggressive environments.
1. Threaded cable passage in various Pg diameters (types with pre-code ”C”) or metric passage (types with pre-code ”M”) in accordance with EN 60423, for cable entry devices in accordance with EN 50262 (NPT threading on request), may be located vertically, horizontally or frontally.
2. Sturdy foundry grade aluminium alloy enclosures with stainless steel treated pegs.
Fixed surface-mounted, bulkhead and hood versions are available.
3. Metallic enclosures with a coated finish of epoxy-polyester with high resistance to mechanical stress and external agents.
New chromate die-casting treatment (RoHS compliant) providing 50% improvement in resistance in salt spray tests (according to UNI EN ISO 9227) compared to the previous green versions.
4. The inserts are made of UL certified selfextinguishing fibreglass reinforced thermoplastics, and feature an operating temperature range between -40 °C and +125 °C.
5. Insert profile polarised with asymmetrical guides to avoid incorrect matings.
The inserts have a mechanical life equal to or higher than 500 mating cycles.
6. Inserts are manufactured in compliance with European standard EN 61984 (DIN VDE 0627), certified and identified with UL, CSA, CCC, GL and GOST markings.
7. Gaskets in anti-aging, oil-resistant and fuel-resistant fluoro elastomer.
8. Stainless steel closure levers and springs guarantee a perfect closure and sealing.
9. Locking device available in two versions, simple (with one lever), or double (with two levers).
10. Captive insert fastening screws, with antislackening spring washer.
11. Contact position identified with numbers or codes on both sides of each insert and printed with a laser system or from a die.
12.Protective earth terminal with a wide contact surface.
13. Supplementary insulation inside enclosures.
Enclosures for aggressive environment
CLASS series enclosures sees the introduction of new versions for Heavy Duty aggressive environments distinguishable by the colour RAL 9005 black.
The Heavy Duty series is specially designed for industrial applications where particularly aggressive external agents are present (e.g. salty environments, etc.).
The range includes enclosures in the 8 basic sizes and in dual versions with 32 and 48 poles.
The enclosures may be bulkhead, surface-mounting or hoods with side or top entry.
The new version is distinguished by the black colour and has the following characteristics:
- new chromate die-casting treatment (RoHS compliant) providing 50% improvement in resistance in salt spray tests (according to UNI EN ISO 9227) compared to the previous green versions.
- oven painted with epoxy polyester powder (improved resistance to chemical agents compared to epoxy polyester).
Other construction characteristics are:
1) CKA..W and MKA..W series
- 21.21 size inserts
- gaskets in anti-aging fluoro elastomer
- monoblock locking device in stainless steel
2) CH..W, CA..W and MH..W, MA..W series
- 44.27, 57.27, 77.27, 104.27, 77.62, 104.62, 66.40 size inserts
- gaskets in anti-aging fluoro elastomer
- pegs in stainless steel
- CLASS type levers (stainless steel lever body, springs and pins, lever in thermoplastic material reinforced with glass fibers)
- supplementary insulation inside enclosures
3) CZ..W and MZ..W series
- 49.16, 66.16 size inserts
- locking device with levers, springs and pins in stainless steel
- pegs in stainless steel
- supplementary insulation inside enclosures
UL approved for USA and Canada for protection ratings UL Type 4 (= NEMA 4), UL Type 4X (= NEMA 4X) and UL Type 12 (= NEMA 12) according to the American standard ANSI/UL 50.
With connector complete and with appropriate cable glands, it is possible to guarantee IP44, IP66 protection compliant with EN 60529 and IP69K compliant with DIN 40050-9 (water jet at 80 °C (± 5 °C) at a pressure of 80bar ÷ 100 bar, for a period of 30s for each angle of inclination 0°, 30°, 60° and 90° w.r.t the plane).
Ambient temperature limits from -40 °C to +125 °C.
Enclosures can accommodate all connector inserts with crimp, screw, spring and the innovative Squich ® connection.
The enclosures do not have any internal tabs and therefore allow insertion of CME inserts with rated voltage of 830V, thanks to the additional insulation strips placed inside.
The new series joins the family of traditional CLASS series enclosures and will support the various solutions: standard (grey), for temperatures up to 180 °C (red), with protection rating IP68, in thermoplastic insulating material (T-Type) and with vertical lever locking system (V-Type).
The new enclosures for aggressive environments in RAL 9005 black replace the previous and similar green versions.
