Description
Design Principles
Temperature protection:
When ambient temperature exceeds the specified value, the inside bimetal of ST10 series motor protector will trip off to cut the circuit. When the temperature lowers down, the bimetal will reset and the circuit is connected again.
Current protection:
Auxiliary heater works together with bimetal, which can control the trip off time precisely. When the current exceeds the prescribed value, ST10 will cut the circuit immediately.
Applications:
• Electrical tools, mixer, water pumps and cleaners
• Electric motors
• Washing machines, ballasts, transformers
