Switching of inductive power
Inductive loads need additional measures for spark sup-
pression. Diodes for DC voltage and varistors / RC ele-
ments for AC voltage are suitable. Some DC coil contac-
tors contain rectifiers which suppress sparks perfectly.
Relay contact service life
Mechanical 500 000 switching cycles
Electrical (250 V AC):
0.5 A: 100 000 cycles
1.5 A 50 000 switching
Internal clearance and creepage distances relay
contacts to 24 V circuits
> 5.5 mm (safety insulation up to 250 V AC)
(EN 60947-1, Pollution degree 2)
Pollution degree terminals 3
Supply power down/up, behaviour: Valid for all
motor control functions, but not for transparent
and overload relay.
Whenever the supply voltage of the UMC is
switched off and on, the starting of the motor
needs a new RUN signal.
