For professional circuit-breaker analysis
The SA5 has been developed for professionals users that wish to fully analyze their medium Voltage circuit breakers. Expand the contact timing tests to include travel results. It only weighs 8,6 kg/ 17lbs.

The versatility and precision that this unity offers is without question unchallenged, and it will indeed be your best partner when testing circuit breakers.

Tests in areas with high induction at known problematic substations has proven the SA10 to be the only circuit breaker timer that could withstand these extreme conditions. It's rugged, it's small and highly appreciated by our customers.

Some SA5 features:
- The well known powerful analysing software BTS11 included.
- Built in a small metal carrying case. All cables and accessories fits in the lid.
- Fully compatible with our factory line test equipment.
- No panel switches, just two push buttons Open and Close.
- Supports both digital and analougue transducers.
- Weighs only 8,6 kg/17 lb.
- Bulit in Printer option for operation without PC
- Automatic measurement of coil and motor current/voltage.
 

Contact Timing.
Three contact input modules of SA5 are designated to be used as main contact channels, and three are designated for auxiliary contact use. It is possible however by using BTS11, to dedicate any of the six channels to handle either.

Number of main contact timing channels: 3(6)
Number of auxiliary contact channels: 3
(The aux inputs can also be used as main contact inputs)

Coils and Motor.
Automatic measuring of circuit breaker coil and motor current/voltage. Together with an adjustable power unit it is very easy to perform minimum function voltage test on the coils.

The SA5 uses 1 analogue channel to measure coil voltage and current and 1 channel to measure motor voltage and current. For the coil 35 A AC/DC is possible for continuous measurement, and for the motor 50A AC/DC. However if necessary higher currents will pass for shorter periods.

Motion Measurements.
The SA5 supports both analogue and digital transducers. A wide range of transducer fastenings can also be supplied. Elcon International is the official world wide supplier of transducer fastenings for ABB-Breakers.

Number of digital transducer inputs: 1
Number of analogue transducer inputs: 1

Analog inputs.
All in all the SA5 has 9 analogue inputs, however since our intension is to provide you with a test equipment that is user friendly and circuit breaker oriented they have been preset to handle specific relevant functions such as coil and motor voltages, currents, analog motion transducers etc.

Communication.
Standard RS232 comunication is default. However, in order to comply with safety regulations a bluetooth comunication kit is available which allows the user to take his laptop pc  and move up to 100m(328ft) away from the test-object.

Printing
The use of a notebook PC and printers are recomended. However as an option we supply the SA5 with a built in printer for basic results printouts.

Further functionality
The SA5 is intended to be used together with medium Voltage breakers or if you only wish to perform basic testing on High Voltage breakers. Should you have increased testing requirements we recommend our Field test equipment SA10.
Additional features that you get with the SA10:

- Built in static and dynamic resistance measurement capability.
- Two additional digital transducer inputs.
- Two additional analogue transducer inputs.
- 12 contact timing channels specially designed to withstand high induction environments.
- 12 channels to measure pre-insertion resistors.
- 3 additional auxiliary contact channels.
- Possibility to perform Full analysis on breakers with Switch synchronisation relays(switch control).
- Possibility to perform "First Trip" analysis.
