MOTOR PROTECTION UNITS WITH THERMOCONTACTS

Generalities:
The motor protection units type S-DT16(E) are specifically designed for the start-up and the protection of 3-phase motors with integral thermocontacts. The integral line protection is assured by a thermal over-current sensor and a magnetic short circuit releasing element. The thermocontact switches automatically OFF in case of motor overheating.

 

Technical features:
• Line voltage 60 .. 500 V (+6%), 50/60 Hz. Applicable from 60 V when voltage control is in use
• Max. line fuse: 80 A (Ue 415 V + 5 %) / 63 A (Ue 440 V .. 500 V + 6 %)
• Max. rated current of motors: 16A
• Setting range over-temperature sensor: 10 .. 16 A
• Rated Short Circuit Breaking Capacity (IEC 60947-2, EN 60947-2, VDE 0660-101): 6 kA (Ue < 400 V + 5 %) / 3.5 kA (Ue = 415 V .. 440 V) / 2.5 kA (Ue 500 V + 6 %)
• Max. adjustable line cross section: 6 mm2 (auxiliary contact: 2,5 mm2)
• Limit ambient temperatures: -25°C / +55°C
• Protection class IP55 or version IP20 for built in
