General Information

The G-Frame instantaneous-only (magnetic) motor cir-

cuit protector (MCP) (Figure 1-1) is available in ratings

from 3A to 63A continuous current for motor starter

sizes 0 through 2. The MCP is designed to comply with

the applicable requirements of Underwriters

Laboratories, Inc. Standard UL489 and the International

Electrotechnical Commission Recommendations No.

IEC 157-1.

The MCP is a UL recognized component under file

E7819. It is used primarily to provide short-circuit pro-

tection as part of a combination controller where other

circuit protective functions are performed by other

devices within the controller. The MCP is suitable for

reverse feed applications. For more information, see

T.D. 29-321.

This instruction leaflet (IL) gives procedures for installa-

tion, operation, inspection, and field testing of G-Frame

MCP's.

2-0 INSTALLATION

The installation procedure consists of inspecting and

mounting the MCP, connecting and torquing the line and

load terminations, and attaching terminal shields when

required. To install the MCP, perform the following steps:

NOTICE

G-Frame MCP's are factory sealed. UL489 requires

that internal accessories be installed at the factory.

Mounting hardware (where required) is supplied in a

separate package.

2-1. Make sure that the MCP is suitable for the intend-

ed installation by comparing nameplate data with sys-

tem requirements. Inspect the MCP for completeness

and damage before mounting.
