13.1 General Description

The Quick Release Drawout Case permits the relay to be removed
from service without disconnecting the wires. The MP-3000 Drawout
MP-3000
Relay maintains the same electrical and operating specifications as
the standard MP-3000. Specifications for the Drawout connectors are
shown in Table 13.2.
Make/Break Rating
Terminal Wire Gauge
Screw Torque Requirements
The MP-3000 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.
Catalog Number
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
MP-3011
Alarm (refer to Subsection 13.4 for more information).

13.2.1 Panel Preparation
MP-3112
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
MP-3113
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.
