GENERAL ELECTRIC CL03A301MD Product Description

Overview

GENERAL ELECTRIC CL03A301MD is a GE Series CL three-pole magnetic contactor with screw terminals. The CL03 family is listed in GE contactor literature for motor and non-inductive load switching; related CL03A301 suffix variants are rated around 25 A AC-3 and 45 A AC-1 at 400 V. The suffix MD likely identifies the coil voltage or coil option, but public search did not return an official GE datasheet for the exact CL03A301MD part number, so coil voltage and auxiliary contact arrangement must be verified from the contactor label, GE order code or original wiring diagram.

Features

The CL03 contactor series provides three-pole power contact switching for AC motor control and non-inductive load control. GE literature lists Series CL contactors with control circuit AC up to 690 V or DC up to 440 V, terminal numbering according to EN 50005 and EN 50012, and mounting by clipping onto a 35 mm DIN rail per EN 50022-35 or by screws. Screw terminals are protected against accidental contact per the referenced VDE or VBG safety practice.

Related public records for CL03A301 variants list rated operational current Ie at AC-1, 400 V as 45 A, and AC-3 motor current around 25 A. The CL03A301M5 record lists three main normally open contacts and a 220 V 50/60 Hz AC coil, while CL03A301MW lists 415 V at 50 Hz or 460 V at 60 Hz control supply. The MD coil code in the GE AC coil list is not mapped clearly from the available catalogue excerpt; do not assume 480 V, 220 V or another voltage without checking the label.

GE Series CL standards referenced include IEC/EN 60947-1, IEC/EN 60947-4-1, IEC/EN 60947-5-1, EN 50005, UL 508, NEMA ICS 1, BS 5424 and 775, CSA 22.2/14, NFC 63-110, ASE 1025, VDE 0660/102 and CENELEC HD 419. CL03 protection degree is listed as IP10 in the GE excerpt. Front or side instantaneous auxiliary contact blocks, timed auxiliary contact blocks, mechanical latch, transient suppressor block and interface modules can be mounted according to Series CL accessories.

Principle

A magnetic contactor switches motor or load power contacts when its control coil is energized. The coil attracts the moving contact assembly, closing the three main NO poles to connect supply phases to the motor or load. Auxiliary contacts, if fitted, switch control-circuit status or interlock signals for PLC inputs, relay logic, indicator lamps or reversing contactor interlocking. The contactor does not provide overload protection by itself; a motor starter normally pairs it with an overload relay or motor protection breaker.

Replacement should verify the exact GE model and suffix, coil voltage and frequency, AC or DC coil, main pole count, auxiliary NO or NC contact count, contact rating, load type, motor kW or HP, supply voltage, terminal layout, DIN rail or screw mounting, coil suppressor, mechanical latch and any reversing or interlock wiring. Because the MD coil rating is not confirmed publicly, compare the rating plate, coil part number and original starter drawing before installing to avoid coil burnout or contactor failure.

Applications

GENERAL ELECTRIC CL03A301MD is used in existing GE-controlled three-phase motor starters for pumps, fans, compressors, conveyors, machine tools, packaging machines, mixers, extruders, material handling, process skids, HVAC equipment and general industrial panels. In legacy installations, it serves as a direct replacement contactor spare when the coil voltage, pole configuration, auxiliary contacts, load rating, terminals and mounting match the original Series CL contactor.
