HTOR Series Thermal Overload Relays
The HTOR series bimetal-style thermal overload relays mount directly to the HMC contactors to protect AC circuits and motors from overloads and phase failures which could damage these components. In addition, the relays also help to protect against long starting times and prolonged motor stalling.
Features of the HTOR series relays include:
- six frame sizes are available in ratings up to 400A
- phase-loss and current unbalance sensitivity protection
- Class 10A trip class
- adjustable trip current
- temperature compensation from 23-104F (-5 to 40 C).
