РТН-2355 thermal overload relay 28…36А

РТН-2355 thermal overload relay with possible I_max calibration 28…36А 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.
