The MPSC-2000 K-Line retrofit kit is supplied
complete with CT module, sensors, magnetic latch,
mounting hardware and instructions.
MPSC-2000 is available in convenient retrofit kits for
upgrading installed breakers with electro-mechanical,
solid state, and earlier generation microprocessor trip
devices
The compact size of the MPSC-2000 allows it to be used to retrofit
virtually any low voltage power circuit breaker by any manufacturer. And
the modular approach to MPSC-2000 design provides added flexibility,
with a separate CT module and on-board mounting of the optional VIM.
Each K-Line retrofit kit includes the MPSC-2000, detailed instructions for
operation and retrofit installation, and the following components:
• Current sensors
• Magnetic latch
• Barriers and supports
• Wiring harness
• Hardware
BTSB
The Benchtop Trip Simulator for Breakers (BTSB) is a microprocessor
driven secondary current/voltage injection test set specifically designed
for use with the MPS-C and MPSC-2000 microprocessor-based trip
devices.
The BTSB can test all facets of MPSC and MPSC-2000
operation, including the following:
•
Instantaneous Threshold
•
Short Time Threshold & Delay
•
Long Time Threshold & Delay
•
Ground Threshold & Delay
•
Current Metering Accuracy
•
Self-Power Level Verification
Altogether, the BTSB can perform up to 35 tests on an MPSC, and all the
tests are performed by true secondary current or voltage injection. There
are also built-in calibration tests which can be performed to ensure that
the BTSB is providing accurate results.
