Use of Overload relays LS MT series
Overload relay LS is an auxiliary electrical device used to protect motors and circuits from overload, with a 3-pole thermal bimetal structure. When a fault is detected, it will automatically disconnect the power circuit to protect the load, the process to perform takes time from a few seconds to a few minutes of impact. In addition, the thermal relay does not automatically trip in the event of a short circuit.
Advantage of Overload relays LS MT series
- Compact design saves space.
- Anti-fingerprint design.
- World class products according to IEC and UL standards.
- Environmentally friendly products: comply with the Safe Electronic Equipment Standard RoHS rule.
