Product Description
WEG BCXML11 Auxiliary Contact Block — 1 NO + 1 NC, Side Mount
The WEG BCXML11 is a side-mount auxiliary contact block for WEG CWM series IEC contactors. It provides 1 Normally Open (NO) + 1 Normally Closed (NC) auxiliary contacts and mounts to the side of CWM contactors rated from CWM9 through CWM300. The BCXML11 uses screw terminals, is rated for 660/690V insulation voltage, and is the authorized replacement for the GE BCLL11 auxiliary contact block.

Product Features
- 1 NO + 1 NC Side-Mount Configuration: The BCXML11 adds one Normally Open and one Normally Closed auxiliary contact to any compatible WEG CWM contactor by mounting to the side of the contactor body. This is distinct from the front-mount BCXMF series (BCXMF10, BCXMF01) which attaches to the front face. Side mounting is typically used when additional auxiliary contacts are needed alongside an existing front-mount block, or when panel space requires side placement.
- Compatible with CWM9 through CWM300: The BCXML11 fits the full range of standard WEG CWM IEC contactors from the smallest frame (CWM9, 9A AC-3) through the CWM300 (300A AC-3). Up to two BCXML11 side blocks can be installed on CWM9 through CWM105 contactors. For the larger CWM400 through CWM800 contactors, the BCXML11 CWM800 is the correct part — not this BCXML11.
- Authorized GE BCLL11 Replacement: The BCXML11 is the authorized WEG replacement for the GE BCLL11 auxiliary contact block. If your panel documentation, BOM, or equipment schematic references the GE BCLL11, the WEG BCXML11 is the correct current replacement.
- Screw Terminals, 14–10 AWG: Both the NO and NC contact circuits use screw terminals accepting 14–10 AWG wire at 0.8 Nm tightening torque. Rated insulation voltage Ui max is 660/690V.
- Second Side Block Available: If more than one set of side-mounted auxiliary contacts is needed, the BCXMRL11 is the second side-mount block (1 NO + 1 NC) designed to stack with the BCXML11 on CWM9–CWM300 contactors.

Frequently Asked Questions
What is the difference between the BCXML11 and the BCXMF10?
The key differences are mount orientation and contact configuration. The BCXML11 is a side-mount block providing 1 NO + 1 NC and is compatible with CWM9 through CWM300. The BCXMF10 is a front-mount block providing 1 NO only and is compatible with CWM9 through CWM105. If you need both NO and NC contacts in a single auxiliary block, the BCXML11 is the correct choice. If you only need a NO contact and prefer front mounting, use the BCXMF10.
Will the BCXML11 fit a CWM400 or CWM500 contactor?
No — the standard BCXML11 is compatible with CWM9 through CWM300 only. For CWM400 through CWM800 contactors, the correct part is the BCXML11 CWM800, which is a separate product with a different mounting interface. Ordering the standard BCXML11 for a CWM400+ contactor will result in an incompatible part.
Is the WEG BCXML11 a direct replacement for the GE BCLL11?
Yes — the WEG BCXML11 is the authorized replacement for the GE BCLL11 auxiliary contact block. WEG acquired the GE Industrial Solutions motor control product line, and the BCXML11 is the current production successor to the GE BCLL11. The contact configuration (1 NO + 1 NC, side mount), voltage rating (660/690V Ui), and CWM/CR contactor compatibility are maintained.
How many BCXML11 blocks can be installed on a single CWM contactor?
Up to two side-mounted auxiliary contact blocks can be installed on CWM9 through CWM105 contactors. The first block is the BCXML11. The second block is the BCXMRL11 (also 1 NO + 1 NC, side mount, second position). This allows up to 2 NO + 2 NC total from side-mount blocks alone, or combined with a front-mount block (BCXMF10 or BCXMF01) for even more auxiliary contact configurations.
Does the BCXML11 qualify for same-day shipping?
Yes — the BCXML11 is a stocked item at Kent Electrical Supply’s warehouse in Emmaus, PA. Orders placed before 4:00 PM EST ship same business day. For bulk orders or related CWM contactor accessories, call us at 1-800-222-5129 or text your RFQ to 484-425-0652.
