РТН-1322 thermal overload relay 17…25А

РТН-1322 thermal overload relay with possible I_max calibration 17…25А is designed to protect AC circuits and motors against:

• overloads
• phase failure
• long starting time
• prolonged stalled rotor condition

The thermal relay controls permanently the current driven by the motor. When this current exceeds the setting it's auxiliary contacts will change state, causing the motor to stop.
