REES EXPLOSION PROOF CABLE OPERATED SWITCHES

Rees, Inc. now offers rugged cable operated switches for use in hazardous atmospheres as defined by the National Electric Code handbook and the National electrical Manufacturers Association Stands for NEMA 7 and 9 hazardous locations.  Specifically, they are listed for Class I, Division 1, Groups C and D and Class II, Division 1, Groups E, F and G.

These switches provide a quick positive shut off of dangerous equipment in an emergency or normal operation by pulling on the attached cable.  The output contacts can control up to two separate circuits, one for machinery shutdown and one for alarm.

Available styles include:

• Taut cable with broken cable detection
• Slack cable with a positive safety lock
• Slack cable with flag status indicators

Operators of conveyors, assembly lines, material handling systems, etc. will be provided with a means to safely and quickly stop equipment with the pull of a cable installed for easy access.

NEMA Type 7 – Hazardous Locations – Class I, Groups C or D (Flammable Gasses)

Designed to meet the applications requirements of the National Electrical Code and is in accordance with the latest specifications of Underwriters’ Laboratories, Inc., for Groups C and D, Class I (Atmospheres containing ethyl ether vapor, ethylene, cyclo-propane, gasoline, hexane, naphtha, benzene, butane, propane, acetone, benzol, lacquers, solvent vapors and natural gas).

NEMA Type 9 – Hazardous Locations – Class II, Groups E, F and G (Combustible Dust)

Designed to meet application requirements under the National Electrical Code and also in accordance with Underwriters’ Laboratories for requirements of Class II, Group E, F and G locations.  (Atmospheres containing metal dust, including aluminum, magnesium (and their commercial alloys), and other materials of slightly hazardous characteristics:  carbon, black coal or coal dust, flour, starch or grain dust.)

Class I, Division 1 – Where ignitable concentration of flammable gases, vapors or liquids can exist all of the time or some of the time under normal operating conditions.

Features/Applications
Features/Applications These contact blocks are designed for use on ALL REES push button operators and selector switches as shown on the preceding pages. The mechanical life of these devices is 1,000,000 operations. Each captive terminal on the contact block will accept (2) # 14 AWG stranded wires and the contacts are gold plated to eliminate high resistance tarnishing.
The 52702 block consists of a B block (50702) attached to an adapter. This adapter Opens the NC contact of the B block Upon Removal from the switch operator. The OUR action provides an added level of security for instances where a NC block may be removed from the operator.

Available in Lockable, Push-Pull, and Momentary versions, the following switches are hand operated, control circuit devices, rated ‘Heavy Duty’ normally for use with electromagnetic equipment.  The body is made from die-cast zinc.  The mushroom shaped plungers are molded from DuPont Delrin 100ST Acetal for improved impact resistance and are solid colors throughout.

• Nema 12/13, IP 65
• Gold Plated Contacts

Each operator will accept up to three tiers of two contact blocks for a total of six separate blocks.  Each operator is supplied with all mounting hardware and a Buna-N (NBR) o-ring which provides an oil tight seal upon installation.  The mechanical life of these units is 1,000,000 operations. 

These devices can be found on a variety of machinery, used to perform such operations as ‘start’, ‘stop’, ‘top stop’, ‘inch’, ‘jog’, ‘on’, ‘off’, ‘forward’, ‘reverse’, etc.

The 22102 series satisfies the requirements of IEC 60947-5-5 – 3.9 direct opening action (positive opening action) (of a contact element); when one or more of any of our normally closed contact blocks are fitted on any red operator.  This is commonly referred to as “Positive Break”, meaning the breaking of the normally closed contact(s) is not dependent upon springs.

Designated switches have been certified as Emergency Stop Pushbuttons and are listed under UL/NISD File E357870, Sec. 1. These switches were evaluated for NISD mounted in a UL type 12/13 enclosure.

Features/Applications
The following selector NEMA 12/13, IP65 switches are hand operated, control circuit devices, rated ‘Heavy Duty’ normally for use with electromagnetic equipment. The die-cast zinc body, is painted with a dry powder paint. The die-cast zinc wing lever is either painted black or nickel plated. Each terminal will accept (2) #14 AWG stranded wires. The switches are supplied with all mounting hardware and a solid neoprene rubber gasket which provides an oil tight seal upon installation. The mechanical life of these devices is 500,000 operations. These switches can be found on a wide variety of machinery. Their rugged construction and long term reliability make these switches extremely well suited to function within various industrial conditions.
