Note:
  1. The standard contact material AgCdO can be replaced by AGSNO2 gold flashed by adding a letter B in its product name, ex.BTA2-1C-B-S2-CBlank: AGCDO B: AGSNO2 gold flashed
  2. You can choose terminal style by switching the codes. For instance : BTA2-1C-B-S-C(6.35X0.8) can be changed toBTA2-1C-B-S1-C(4.8X0.8)S: 6.35X0.8 S1: 4.8X0.8 S2: 4.8X0.5 P1: 2.3X0.8 P2: 1.2X0.8 (See Terminal Style figure below)
  3. You can choose cover style by switching the codes. For instance : BTA2-1C-B-S2-C( plain cove) can be changed toBTA2-1C-F-S2-C1(side flange cover)C: plain cover C1: side flange cover C3: top flange cover C4: din rail cover

Note:
  1. The coil resistance is measured at a coil temperature of 25℃ and 35%-70% of humidity.
  2. The operating parameter is measured at a coil temperature of 25℃ indicated in the percentage of the rated voltages.
  3. The coil rated current is measured as the real current consumption under the rated voltages.
