NOTES:
1. * = any digit covering all pickup ranges, instantaneous,
non-instantaneous, and 50 Hz and 60 Hz models.
2. Units with instantaneous elements are designated with a "B" for the
eighth character in the model number.

NOTE: The -229 is based on and offers the same functionality as the -214 IAC replacement. Available curves and outputs (one 50 and one 51
contact) are identical to the BE1-50/51B-214.

ELECTROMECHANICAL REPLACEABLE MODELS
IAC models that may be retrofitted with the BE1-50/51B:
• The 244 is a direct replacement for a CO relay in a
case that fits an FT-11 size cutout. It has an
additional low-set instantaneous to help reduce arc
flash hazard.
• The 240 and 241 are direct replacements for a CO
relay in an FT-21 case. The 241 has an additional low-
set instantaneous to help reduce arc flash hazard.
• The 219 or 226 kit is a direct replacement for a CO
drawout relay in an FT-11 case.
• The 214, 225, or 231 kit is a direct replacement for an
IAC drawout relay.
• The 231 kit or 232 direct replacement relay replaces a
single element IAC relay with a dual element relay.
• The 229 is a direct replacement for selected SFC
drawout relays.
• The 230, 234, and 239 are direct replacements for the
IAC66K motor protection relay.
• The 215 is a retrofit for the IAC66C relay, except
Terminals 1 and 9 are internally connected.
• The 235 or 236 kit is a direct replacement for a CO
drawout relay in an FT-11 case. It has an additional
low-set instantaneous to help reduce arc flash hazard.
• The 237 or 238 kit is a direct replacement for an IAC
drawout relay with an additional low-set instanta-
neous to help reduce arc flash hazard.
• No electrical or mechanical rework is required to
panels during retrofit.
• Competitively priced.
• One model replaces more than 100 IAC or 40 CO
models in an FT-11 case listed on next page.
• Patent #5,751,532.
• Numerous technical advantages:
- All units are equipped with an instantaneous element.
- Instantaneous element can be set lower, because the
relay is corrected for transient overreach.
- Therefore, the range does not need to be as high as on
the IAC relay.
- Ten selectable curves and wide pickup ranges.
- Lower burden extends linear range of CTs.
- Self-calibration feature eliminates need for recalibration,
thereby reducing maintenance labor.
