Electric Pin & Sleeve Devices - Introduction |

| Worldwide
Interchangeability |
| Walther's pin & sleeve devices
are built to IEC 309-1 and 309-2 specifications and are interchangeable with
other manufacturers who conform to the IEC standards and color coding
system...anywhere in the world. Manufacturers that do not comply with the
standards have their own proprietary configurations and are not plug compatible
with other pin & sleeve products. Once you have selected a proprietary
configuration you are locked in to a single source. Specifying IEC 309-1 &
309-2 devices provides convenience and flexibility that users have come to
accept almost without thinking. |

| Safety |
| IEC 309-2 configurations for plugs
(or inlets) and receptacles (or connectors) are single-rated which assures
proper mating of devices with the same voltage and amperage. It is virtually
impossible to couple a plug and receptacle of different voltage and/or amperage
ratings. |
The size of the device is
determined by the amperage rating. plugs and receptacles of different amperage
ratings are not compatible because of the size variance.
Many
proprietary pin & sleeve configurations, that do not conform to the IEC
standards, are designed to accommodate multiple voltage systems. A plug wired
to a piece of equipment designed to operate at one voltage system could
unintentionally be plugged into a receptacle wired with an unlike voltage.
Mismatching voltages could cause damage to the equipment or even personal
injury and is not considered safe electrical practice. |
| Plugs and receptacles rated 60 amps and above,
feature an "electrical interlock" by way of a pilot pin on the plug and female
sleeve on the receptacle that is shorter than the main pins. The pilot pin and
female sleeve make contact last, and break contact first. The sequence turns
the power on when the pilot pin and sleeve mate, and turns the power off before
the phase contacts are disengaged. This prevents making or breaking the circuit
under load. |

The voltage, of single rated Pin
& Sleeve devices of the IEC 309-2 type, is determined by the location of
the oversized female ground contact relative to the key-way located at the
bottom of the housing. A clock face is used to represent the location of the
ground sleeve for a specific voltage system. For example, a 480 VAC receptacle
or connector will have the oversized ground sleeve located in the 7 o' clock
position. The corresponding grounding pin location on the plug or inlet is a
mirror image of the female device. Devices of mismatched voltage systems simply
cannot be mated. Each device is clearly marked with the voltage system for
which it is intended to be used. The insulated housing is made from a high
impact, nylon material. The nonmetallic device, while abuse and corrosion
resistant, is also nonconductive, which enhances the safety of the
product. |

| Reliability |
Walther offers the widest variety of
plugs, receptacles, connectors and inlets, made of the highest quality and
design integrity in both splashproof and watertight versions.Watertight (IP67)
devices are designed for use in the most demanding environments that require
safety, ease of use, reliability and durability. These devices can withstand
impact and vibration and provide complete protection against dirt, dust, water
jets and even temporary flooding. Watertight devices are available in 20, 30,
60, and 100 amp (North American) ratings and 16, 32, 63 and 125 amp
(International) ratings.
Splashproof (IP44) devices are suitable and
recommended for use in a variety of light industrial environments and provide
complete protection against contact with live parts, damaging deposits of dirt
and dust and splashing water. Splashproof devices provide many of the heavy
duty construction features found in the watertight products, but at a more
economical cost. Splashproof devices are available in 20, 30 and 60 amp (North
American) ratings and 16, 32 and 63 amp (International)
ratings.
Watertight and splashproof devices provide exceptional UV
stability for superior outdoor performance.
All Walther plugs and
connectors are supplied with an internal cord clamp designed to firmly grip not
only the outer cable jacket, but also the internal conductors. The internal
cord clamp eliminates strain on the terminals while providing high pull-out
values without external protrusions to snag adjacent wiring or the
installer.
In addition to the internal cord clamp, Watertight plugs and
connectors are also supplied with an external cable gland. This cable gland
serves as a secondary method of eliminating strain on the terminals and
conductors while assuring watertight performance. Standard splashproof plugs
and connectors are also supplies with the same external gland as the watertight
devices. However, a cable sleeve, designed to speed up installation, is
provided with a lower cost splashproof alternative.
All Walther plugs
and connectors, furnished with either a cable gland or cable sleeve, meet the
cord and cable secureness requirements defined in UL 1682, Section 33. |
