j | BA 14.0204 | 02/2012 Technical data Disengagement time The disengagement time is not affected by DC or AC switching. The indicated disengagement time applies to an air gap of 0.4 mm. When the air gap is larger (as a result of wear), the disengagement time increases. -
Page 17: Emission
j | BA 14.0204 | 02/2012 Technical data Emission Heat Since the brake converts kinetic energy as well as mechanical and electrical energy into heat, the surface temperature varies considerably, depending on the operating conditions and possible heat dissipation. Under unfavourable conditions, the surface temperature can reach 130_C. -
