Product Description
WEG CWM9 IEC Contactor — 9A, 3-Pole | Authorized GE CL00A310T Replacement
The WEG CWM9 is a 9A, 3-pole IEC contactor from the WEG CWM series, rated for 3 HP at 230V and 5 HP at 460V three-phase (9A AC-3 / 32A AC-1). It ships standard with 1 Normally Open (NO) auxiliary contact, screw terminals, and mounts on 35mm DIN rail or panel backplate. The CWM9 is the authorized replacement for the obsolete GE CL00A310T contactor, identical in dimensions and electrical operation.

Product Features
- Authorized GE CL00A310T Replacement: WEG officially established the CWM9 as the replacement for the discontinued GE CL00A310T contactor line. The CWM9 is dimensionally and electrically identical — same mounting footprint, terminal spacing, and auxiliary contact interface. Existing GE CL00 overload relays and auxiliary blocks are compatible with the CWM9.
- 1 NO Auxiliary Contact Included: The CWM9 ships standard with 1 Normally Open (NO) base-mounted auxiliary contact. Up to 4 additional contacts can be snap-added using BCXMF10 (1 NO, front-mount), BCXMF01 (1 NC, front-mount), or BCXML11 (1 NO/1 NC, side-mount) blocks.
- Direct-Mount Overload Relay (RW27-1D3): The WEG RW27-1D3 series thermal overload relay mounts directly to the load-side terminals of the CWM9 for complete motor protection. Select the RW27-1D3 current range from 0.28A to 12.5A to match your motor’s full-load amperage (FLA). The combination forms a compact, wiring-free motor starter assembly.
- Wide Coil Voltage Range: Available in 24V, 120V, 208–240V, and 480V AC coil variants to match any standard US control circuit. Wide-range coil tolerance provides reliable operation across typical voltage fluctuations.
- Compact — Panel Space Efficiency: The CWM9 is the smallest 3-pole contactor in the WEG CWM lineup. Its compact body is ideal for high-density panel layouts. The CWM9, CWM12, and CWM18 share the same mounting footprint as the corresponding GE CL00, CL01, and CL02 series, making exact panel retrofits straightforward.
- IP20 Finger-Safe Control Terminals: All control circuit terminals meet IP20 finger-safe protection, compliant with UL and IEC safety requirements for open-panel installations.
- Mirror Contacts Available: The CWM series supports mechanically-linked mirror contacts for safety-related applications. Contact Kent Electrical Supply at 1-800-222-5129 for mirror contact accessory options.
- Global Certifications: UL 508 Listed, CSA Certified, IEC 60947-4-1 compliant, CE marked for worldwide installation compliance.

Frequently Asked Questions
Is the WEG CWM9 a direct replacement for the GE CL00A310T?
Yes — the WEG CWM9 is the officially authorized replacement for the obsolete GE CL00A310T contactor family. WEG and GE established this cross-reference to guarantee complete dimensional and electrical compatibility. The CWM9 matches the GE CL00 in mounting footprint, terminal spacing, auxiliary contact position, and overload relay interface. Select the correct coil voltage variant (see table above) to match your existing installation. Any GE CL00 accessories already installed remain compatible with the CWM9.
How do I find the coil voltage on my existing GE CL00A310T?
The coil voltage on GE CL00, CL01, and CL02 contactors is printed on the top of the contactor between the A1 and A2 coil terminals — not on the side label. The side label shows line voltage ratings (230V, 460V, 600V), which are not the control coil voltage. See our detailed guide: How to Find the Coil Voltage on a GE CL00, CL01, or CL02 Contactor. Or call us at 1-800-222-5129.
What do the GE CL00A310T coil suffix codes mean?
The letter at the end of the GE CL00A310T catalog number identifies the coil voltage: TJ = 120V AC (most common US), T7 = 208–240V AC, T3 = 480V AC, TT = 24V AC. Match your existing suffix to the corresponding WEG variant: TJ → CWM9-10-30V18, T7 → CWM9-10-30V24, T3 → CWM9-10-30V47, TT → CWM9-10-30V04.
What is the difference between CWM9, CWM12, and CWM18?
These are the three smallest frame sizes in the WEG CWM series, directly replacing GE CL00, CL01, and CL02 contactors. The CWM9 is rated 9A AC-3 (5 HP @ 460V, overloads to 12.5A), the CWM12 is rated 12A AC-3 (7.5 HP @ 460V, overloads to 15A), and the CWM18 is rated 18A AC-3 (10 HP @ 460V, overloads to 23A). All three share the same accessory system (BCXMF/BCXML aux blocks, RW27 overloads). Select based on your motor’s horsepower and full-load amperage at your supply voltage.
Which overload relay is compatible with the CWM9?
The WEG RW27-1D3 series thermal overload relay mounts directly to the bottom load-side terminals of the CWM9, forming a complete motor starter without additional wiring. For the CWM9, overload current ranges from 0.28A to 12.5A are applicable. Select the range that covers your motor’s nameplate FLA. Call us at 1-800-222-5129 if you need help choosing the right range.
Is the CWM9 in stock for same-day shipping?
Yes — common CWM9 coil voltage variants are stocked at Kent Electrical Supply’s warehouse in Emmaus, PA. Orders placed before 4:00 PM EST ship the same business day. Current stock quantities are shown on each individual variant page. For bulk orders or other coil voltages, call us at 1-800-222-5129 or text your RFQ to 484-425-0652.
