PRODUCT GUIDE
PRODUCT OVERVIEW
DESCRIPTION & DESIGN FEATURES
Applications
R49 & R24 series connectors can be used wherever high amperage connection of
AC or DC power is required. Typical applications are the connection of power
from generator sets to Switchgear or SCR houses. Traction motors, mud pumps,
drawworks, rotary tables, cement pumps and top drives.
Electrical Integrity
R49 & R24 series connectors are designed to run at full rated load and
complement the latest drilling cable electrical ratings.
Operator Safety
The inherent design of the connectors is such that the electrical contacts are
shrouded by the Rubber insulations and the male ( power side ) has a dead
front end to protect operators from shock hazard. Connectors are rated @1000
VAC or DC current with the ability to withstand intermittent surges up to 1300
amps.
Phase Identification
Connectors are color coded to provide easy circuit identification. Colored
insulations for both AC and DC circuit. Color coding prevents reverse phasing
or cross polarization of DC circuits. Receptacle housings are also color coded
to further assist the identification of phases.

INGRESS PROTECTION
Connectors are designed to provide weatheproof servicein a variety of demanding environments. The insulations are resistant to oil, mud, sea water and petroleum products found in the drilling industry. Correctly assembled, the connectors provide safe, trouble free operation in the most extreme working conditions. Certified by CSA.
CONFIGURATIONS
R49 & R24 series connectors are available in all configurations male and
female connectors.
Typical configurations are shown below:
| Power Side | Equipment Side | Use |
|---|---|---|
| Male Receptacle Panel Mount | Female Plug | AC or DC Output side of panel |
| Inline Male Receptacle | Female Plug | Inline cable to cable connections |
| Male Plug Cable Mounted | Female Panel Mount Receptacle | AC power to switch- |
gear
Termination
Termination method is crimp on cable mounted plugs and receptacles and bus bar
termination is provided on panel mounted receptacles. The rubber insulations
can be bonded to the cables by vulcanization. Vulcanizers are available on
request.
Type P Cables
R49 & R24 series connectors are designed to work in conjunction with the
latest generation of Type P drilling cables, per IEEE 45. Cable accommodations
are 4/0 AWG (107mm 2 ) to 777 MCM (394mm2)
Mounting Data
R49 & R24 Series connectors are designed specifically with the requirements of
the drilling industry in mind. A space saving design allows the mounting of
receptacles in very close proximity to each other. This allows operators to
reduce the overall space requirement on switch gear and SCR drives. See
‘Assembly Instructions’ for mounting dimensions
Temperature Ratings
The connectors are designed to operate in both extremes of cold and high
temperature applications. The Insulations are designed to withstand the very
low temperatures found in Artic conditions, in addition to being able to run
at full rated load in high ambient temperatures.
Installation
The simple design of the R49 & R24 series, allows the connectors to be mated
and unmated without the use of tools.
MATERIALS
Receptacle Housings: Oil, Alkaline, UV, and weather resistant, Color coded polyester TGIC powder coating over copper-free aluminum alloy Contacts: Tin- plated copper alloy Insulations: Synthetic Rubber
