MPT1 PTC熱敏電阻繼電器產(chǎn)品信息

MPT1 PTC熱敏電阻繼電器

Introduction:

It is a PTC Thermistor Relay. It offers protections against Over heating of the windings of pumps, motors, transformers, alternators etc. & sense the temperature with the help of PTC thermistor. It can be used with single or triple PTC & also with 6 or 9 PTCs as a special case. It can used for AC/DC motor, generator, transformer, winding protection against over heating of SCRs & Bus Bars.

Features:

· Monitors Overload & Phase Loss, Phase Sequence by sensing Overheating of Windings.
· Operates with Embedded PTC sensors in the motor / transformer windings.
· Suitable for any PTC Thermistor.
· Sensor Short / Open Condition Monitoring.
· 1 CO output rated 230V AC / 5A （Resistive）
· Auto （Optional Manual） Reset.
· Plug-in 8 pin base mounted.

Application Areas:

Injection Molding machines Machine tools Crane & hoist motors Compressors & fan motors
