Applications
Motor monitoring with PTC in the
winding:
• For long starting and braking
operations
• For high switching frequencies
• For increased ambient tempera-
tures
• When the cooling medium flow
is restricted
• For AC drive operation
Highlights
• All products are PTB-ATEX
certified
• Wire breakage and short circuit
in the sensor circuit are displayed
• Versions with hard-gold-plated
relays which are electronics
compatible
• Favorably priced compact device
(A1 + 11 jumpered)
• Either screw or cage clamp termi-
nal connection system
S
The power and lifetime of motors is essentially limited by the winding temperature. Motor
manufacturers integrate PTC sensors in the motor winding if more stringent requirements prevail – e. g.
for high ambient temperatures or where cooling is restricted. The thermistor motor protection devices
operate according to the closed-circuit principle, detect these limit temperatures and switch the output
relay contacts.
