Accessories

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.
