Product Features
- GE CL00A310T Authorized Replacement: The WEG CWM9 is the fully authorized, dimensionally identical replacement for the obsolete GE CL00A310T contactor family. The CWM9 matches the GE CL00 in mounting footprint, terminal spacing, and electrical performance. Existing overload relays, auxiliary contact blocks, and panel cutouts from GE CL00 installations 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 auxiliary contact blocks can be snap-mounted: use BCXMF10 (1 NO) or BCXMF01 (1 NC) for front-mount, or BCXML11 (1 NO / 1 NC) for side-mount.
- Direct-Mount Overload Relay (RW27-1D3): The WEG RW27-1D3 series thermal overload relay mounts directly to the bottom of the CWM9 for complete motor overload protection. Available in current ranges from 0.28A to 12.5A for the CWM9 frame — select the range covering your motor’s full-load amperage.
- Compact Frame — Space-Efficient Panel Design: The CWM9 is the smallest 3-pole contactor in the WEG CWM lineup. Its compact frame is ideal for tight enclosures and high-density panel layouts. Three frame sizes in the CWM range — 9A, 12A, and 18A — share the same mounting footprint as the corresponding GE CL00, CL01, and CL02 series.
- DIN Rail or Panel Screw Mount: Mounts on standard 35mm DIN rail or directly to a panel backplate. IP20 finger-safe protection on the control circuit terminals.
- Wide Coil Voltage Range: Available in 24V, 120V, 208–240V, and 480V AC coil voltages to match any standard US control circuit. Wide voltage range coil tolerance ensures reliable operation across typical supply voltage variations.
- Global Certifications: UL 508 Listed, CSA Certified, IEC 60947-4-1 compliant, CE marked. Suitable for North American and international installations.

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 entire GE CL00A310T contactor family. The CWM9 matches the GE CL00 in mounting footprint, terminal spacing, auxiliary contact positions, and overload relay interface. Any existing GE CL00 accessories remain compatible. Select the correct coil voltage variant from the table above to match your existing installation.
How do I find the coil voltage on my existing GE CL00 contactor?
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. It is not on the side label — that label shows line voltage ratings (230V, 460V, 600V), not the control coil voltage. See our step-by-step guide: How to Find the Coil Voltage on a GE CL00, CL01, or CL02 Contactor. Or call us at 1-800-222-5129.
What is the difference between the GE CL00A310T and CL00A310TJ?
The suffix at the end of the GE CL00 catalog number indicates the coil voltage. CL00A310TJ = 120V AC coil (the most common US variant, replaced by CWM9-10-30V18). CL00A310T7 = 208–240V AC coil (replaced by CWM9-10-30V24). CL00A310T3 = 480V AC coil (replaced by CWM9-10-30V47). CL00A310TT = 24V AC coil (replaced by CWM9-10-30V04).
What overload relay is compatible with the CWM9?
The WEG RW27-1D3 series thermal overload relay mounts directly to the load-side terminals of the CWM9, forming a complete motor starter assembly. For the CWM9, overload ranges from 0.28A to 12.5A are applicable. Select the range that covers your motor’s nameplate full-load amperage. Call us at 1-800-222-5129 for help selecting the correct RW27-1D3 range.
What is the difference between CWM9, CWM12, and CWM18?
These are the three smallest frame sizes in the WEG CWM series, directly replacing the GE CL00, CL01, and CL02 contactors respectively. The CWM9 is rated 9A AC-3 (5 HP @ 460V), the CWM12 is rated 12A AC-3 (7.5 HP @ 460V), and the CWM18 is rated 18A AC-3 (10 HP @ 460V). All three share the same accessory ecosystem and overload relay mounting interface. Select based on your motor’s horsepower and FLA at your supply voltage.
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 less common coil voltages, call us at 1-800-222-5129 or text your RFQ to 484-425-0652.
