The MP-4000 Drawout consists of two assemblies: an inner chassis,
and an outer chassis. The outer chassis consists of an aluminum
housing with terminal blocks, a molded plastic flange with quick-re
-
lease actuators, and a locking mechanism.
The drawout terminal blocks feature self-shorting, or short-before-
break set of contacts, for CT connections that maintain circuit continu
-
ity when the device is removed. These self-shorting contacts prevent
damaging voltages from existing across the current transformer
windings.
An extra set of self-shorting terminals can be used to keep the motor
running while the relay is out of its case, or to provide a No Protection
Alarm (refer to Subsection 13.4 for more information).
13.2 Installation
NOTICE
The following material supplements installation information in Subsec
-
tions 6.0.1 through 6.0.3, and Figures 6.2 and 6.4. Refer to these
sections and figures first.
13.2.1 Panel Preparation
The Drawout Case uses the same panel cutout as the fixed mount
MP-3000, IQ1000II, and IQ1000. When mounting the Drawout Case
in a panel, it is necessary to prepare a cutout for the device per Figure
13.1. If a standard IQ cutout exists, no additional panel setup is re
-
quired. The Drawout mounts securely in an existing 6-hole or 10-hole
cutout.
13.2.2 MP-4000 Drawout Relay Parts list
Before mounting the Drawout Relay, check the contents of the box
against the parts listed in Table 13.3 and shown in Figure 13.2.

13.1 General Description
The Quick Release Drawout Case permits the relay to be removed
from service without disconnecting the wires. The MP-4000 Drawout
Relay maintains the same electrical and operating specifications as
the standard MP-4000. Specifications for the Drawout connectors are
shown in Table 13.2.
