CB-845
Circuit Breaker Test Set
• Digital memory ammeter
• Digital, multirange timer
• Lightweight and portable
• High-current output
• Solid-state output initiate circuitry
The CB-845 test set is a high-current circuit breaker test set consisting of a control unit that incorporates the latest in solid-state metering, control technology and a high-current output unit.
The lightweight, two-section design of Model CB-845 enables the user to easily transport the unit into areas previously inaccessible to high-current test equipment such as elevated or subsurface load centers, shipboard power panels, elevator machinery rooms and other isolated locations.
CBS-1, CBS-2 and CBS-3
Circuit Breaker Stab Sets
• Connect to virtually all Multi-Amp
circuit breaker test sets
• Provide quick connection to breaker under test
• Can accommodate over 70 types of breakers
Model CBS-1 and Model CBS-2 Circuit Breaker Stab Sets allow connection to virtually all Megger circuit breaker test sets. Their use eliminates the significant losses that occur if leads are used to connect the breaker under test to a test set.
These stab sets allow testing of drawout style metal-clad breakers. (Cables must be used when testing molded-case circuit breakers or other devices that will not connect directly to the stab.)
DDA-16, DDA-30 and DDA-60
Digital Data Acquisition Instrumentation and Control System
• Drop-in retrofit capability to the
Multi-Amp Model CB-9116, Model
DB-8130 and Model CB-8160 circuit
breaker test sets
• Digital Signal Processing (DSP) technology
• Variable pulse time and firing-angle
output-current control
• Complies with NEMA AB-4 Test Guidelines
The DDA-16, -30, -60 use the latest in DSP technology to control the circuit breaker test sets and also measure the reactions of the breaker under test. The retrofit capabilities allow a user of Multi-Amp circuit breaker tests sets the capability of upgrading existing systems without the expense of purchasing a new system. The DSP technology provides complete digital control of the SCRs and digitally samples the output current for high-accuracy measurements.
DDA-1600
Circuit Breaker Test Set
• Digital signal processing technology
• Variable firing angle and pulse duration
• Modular, portable design
• Complies with NEMA AB-4 Test Guidelines
Model DDA-1600 is ideal for testing low-voltage breakers rated to 1600-ampere frame size. Incorporating the new Model DDA-1 Digital Data Acquisition Instrumentation and Control System, it provides increased control of output current and high accuracy metering of the breaker under test. A full line of other DDA test sets is available to meet all of your high-current, primary injection testing needs through 6000-ampere frame size.
DDA-3000/6000
Universal Circuit Breaker Test Set
• New DDA-1 Digital Data Acquisition
• High-current output: 60,000 A for
Model DDA-6000 and 35,000 A for
Model DDA-3000
• Variable pulse time and firing
angle output current control
• Complies with NEMA AB-4 Test Guidelines
The DDA-3000 and DDA-6000 are designed specifically to test low-voltage power and molded-case circuit breakers equipped with thermal, magnetic or solid-state trip devices. The unique transformer and circuit design results in a very high-capacity test set in a very compact size. Advanced digital control and instrumentation provides exact testing capacity. The test sets can also be used for other high current applications, such as verifying the ratio of current transformers and performing heat runs or primary injection testing of high-voltage breakers and their associated protective relays.
MS-2
Circuit Breaker and Overload Relay Test Set
• Digital memory ammeter
• Digital, multirange timer
• Rugged and portable
Model MS-2 is used around the world by utilities, industrials and electrical service organizations. It verifies the proper operation of thermal, magnetic and solid-state overload relays; molded-case circuit breakers; and ground-fault trip devices. Completely solid-state output-initiate circuit eliminates the need for contact maintenance. This instrument weighs only 33 pounds yet is tough enough to withstand daily plant or field use.
PS-9116
Microprocessor-Based Circuit Breaker Test Set
• Portable, three piece chassis
• Tests wide range of air-frame breakers
• Test result printout capability
Model PS-9116 offers the latest developments in high-current transformers and microprocessor-based control. It combines lightweight, modular portability with high-current output capacity and maximum testing flexibility. This model incorporates the Model PLC-2000 controller and instrumentation package for storing and printing test results in the field or office. This unit tests most low-voltage breakers rated to 1600 amperes.
PS-9130/9160
Universal Circuit Breaker Test Sets
• Proven power train
• Rugged instrumentation and controls
• Direct connection of draw-out type breakers
• Integral clock/calendar
• Easy-to-read display
Model PS-9130 and Model PS-9160 Series Universal Circuit Breaker Test Sets are specifically designed to test low-voltage power circuit breakers and molded-case circuit breakers that are equipped with thermal magnetic or solid-state trip devices by simulating an overload or fault condition.
Model PS-9130 and Model PS-9160 are controlled by the Model PLC-2000 Prime Logic Controls. This microprocessor monitors the output, stores the test data and performs the automatic test functions. After the test information is stored, Model PLC-2000 can print the test data using a built-in RS-232 printer port.
