Product Features
- GE CL02A310T Authorized Replacement: The WEG CWM18 is the fully authorized, dimensionally identical replacement for the obsolete GE CL02A310T contactor family. WEG and GE established this cross-reference officially — the CWM18 matches the GE CL02 in mounting footprint, terminal spacing, and electrical performance. Existing overload relays, auxiliary contact blocks, and panel cutouts from GE CL02 installations are compatible with the CWM18.
- 1 NO Auxiliary Contact Included: The CWM18 ships standard with 1 Normally Open (NO) base-mounted auxiliary contact. Up to 4 additional auxiliary contact blocks can be snap-mounted: use BCXMF series for front-mount or BCXML series for side-mount. Note: the BCXMF10 (1 NO) is the authorized replacement for the obsolete GE BCLF10 auxiliary block.
- Direct-Mount Overload Relay (RW27-1D3): The WEG RW27-1D3 series thermal overload relay mounts directly to the bottom of the CWM18 for complete motor overload protection. Available in current ranges from 0.28A to 23A — select the range that covers your motor’s full-load amperage. The assembly forms a compact, complete IEC motor starter.
- Compact CWM Series Frame: The CWM18 is part of WEG’s well-established CWM series, rated up to 800A across the full range. The 18A frame is compact and space-efficient — 81mm H × 45mm W × 87mm D — maximizing panel space in tight enclosures.
- 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.
- Mirror Contacts Available: The CWM series supports mechanically-linked mirror contacts for safety-related applications requiring positive-opening auxiliary contacts. Contact Kent Electrical Supply for mirror contact accessory options.
- Global Certifications: UL 508 Listed, CSA Certified, IEC 60947-4-1 compliant, CE marked. Suitable for installations in North America and internationally.

Frequently Asked Questions
Is the WEG CWM18 a direct replacement for the GE CL02A310T?
Yes — the WEG CWM18 is the officially authorized replacement for the entire GE CL02A310T contactor family. WEG and GE established this cross-reference to ensure complete dimensional and electrical compatibility. The CWM18 matches the GE CL02 in mounting footprint, terminal spacing, auxiliary contact positions, and overload relay interface. Any existing GE CL02 accessories will work with the CWM18 without modification. Select the correct coil voltage variant to match your existing installation (see the coil voltage table above).
How many auxiliary contacts does the CWM18 come with?
The CWM18 comes standard with 1 Normally Open (NO) base-mounted auxiliary contact. This is a single NO contact only — not 1 NO + 1 NC. If your application requires additional contacts, snap-on auxiliary blocks can be added: the BCXMF10 (1 NO, front-mount) or BCXML11 (1 NO / 1 NC, side-mount) are common choices. The CWM18 supports up to 4 additional snap-on blocks in total.
Which overload relay is compatible with the CWM18?
The WEG RW27-1D3 series thermal overload relay mounts directly to the load-side terminals of the CWM18, forming a complete motor starter assembly. The RW27-1D3 is available in current ranges from 0.28A to 23A — select the range covering 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 WEG coil code system for CWM18 variants?
WEG CWM18 coil voltage codes use the “V” prefix followed by a two-digit number: V04 = 24V AC, V18 = 120V AC, V24 = 208–240V AC, V47 = 480V AC. The full catalog number format is CWM18-10-30V[code], where “10” indicates 1 NO auxiliary contact included and “30” indicates 3 main poles. Always verify your control circuit voltage before ordering.
What is the difference between the CWM18 and the CWM25?
The CWM18 and CWM25 are adjacent frame sizes in the WEG CWM series. The CWM18 is rated at 18A AC-3 (10 HP @ 460V, 5 HP @ 230V three-phase). The CWM25 is rated at 25A AC-3 (15 HP @ 460V, 7.5 HP @ 230V three-phase). Both accept the same accessory ecosystem (BCXMF/BCXML aux blocks, RW27 overload relays). Select based on your motor’s horsepower and FLA at your supply voltage.
Is the CWM18 in stock for same-day shipping?
Yes — common CWM18 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.
