13.2.1 General Description
The purpose of the Quick Release Drawout Case is to remove the
relay from service without disconnecting the wires. The MP-3000
Drawout Relay maintains the same electrical and operating specifica-
tions as the standard MP-3000. Specifications for the Drawout
connectors are shown in table 13.2.
Table 13.2 Drawout connector Specifications
Make/Break Rating 10 A @ 240 Vac nominal
0.25 A @ 280 Vdc maximum
Terminal Wire Gauge No. 14 to No. 10 AWG
Screw Torque Requirements 18 inch-pounds
The MP-3000 Drawout consists of two assemblies: an inner chassis,
and an outer chassis (see Figure 13.1). The outer chassis consists of
an aluminum housing with terminal blocks, a molded plastic flange
with quick-release actuators, and a locking mechanism.

13.2.1 Self-Shorting Ct Connections
The Drawout terminal blocks features self-shorting, or short-before-
break set of contacts, for Ct connections that maintain circuit
continuity when the device is removed. These self-shorting contacts
will prevent damaging voltages from existing across the current
transformer windings.
An extra set of self-shorting terminals are provided that may be used
to keep the motor running while the relay is out of its case or to
provide a No Protection Alarm (see Section 13.5 for more information).

INFORMATION IN SECTIONS 6.1.1, 6.1.2, AND 6.1.3, AND
FIGURES 6.1 AND 6.3. REFER TO THESE SECTIONS FIRST.
13.3.1 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
13.2. If a standard IQ cutout exists, no additional panel setup is
required; the Drawout will mount securely in an existing 6-hole or
10-hole cutout.
13.3.2 MP-3000 Drawout Relay Parts List
Before mounting the Drawout Relay, check the contents of the box for
the parts listed in Table 13.3 and shown in Figure 13.3.
