Clamp-on Current Probes for the 933A
AP0012300:
100:1, 0.1 – 150 Amp, 10mV/A, EN61010, 600 V, Cat.III.
Use
only
with 933A-02 or 933A-03 low current modules.
AP0012800:
1000:1, 0.1 – 150 Amp, 1mA/A, EN61010, 600 V, Cat. III.
May be used with 933A-01 standard current module. Best with 933A-02
or 933A-03 low current modules because of their greater sensitivity.
AP0012900:
Has three ranges: 250:5, 500:5, 1000:5; 20mA/A–250A max;
10mA/A–500A max; 5mA/A–1000A max; EN61010, Cat. III. Use with
any current module.
AP0001300:
1000:1, 1000A max, 1mA/A, EN61010, 600 V, Cat.III. Use
with any current module. Best with 933A-02 or 933A-03 because of their
greater sensitivity.

Low Current Modules
Two low-current input modules are available for both current-output and
voltage-output CT’s. Each has two ranges; a high range (up to 1.2 Arms
or 2.4 Vrms) and low range (up to 50 mA rms and 100 mV rms) These
two modules are very similar except for the input connectors. The 933A-02
(order no. AS0097800) has two sets of shrouded banana connectors for each
phase, including neutral, that include a voltage input and current input.
The 933A-03 (order no. AS0097900) has a unique single jack that allows
for voltage and current input signals. Arbiter Systems produces dedicated
cable assemblies for the Model 933A-03 to work with this current module.
