Thermal Relay
LR2 Thermal Relay
This series of thermal relay can be used in the circuit of 50Hz or 60Hz, rated insulation voltage 660V, rated current 0.1-93Afor protecting the phase break when the electric motor is overload.
The relay has different mechanism and temperature
compensation, and it can be plugged in LC1-D series ACC ontactor. At present, it is the most advanced thermal relay in the world.
T Thermal Relays
The relay is suitable for using in the power circuit up to rated voltage 660V, rated current 500A 50Hz or 60Hz for overload and loss of phase protection of three phases induction motor and often combined with B series AC contactor into magnetic starter.
T16 & T25 thermal relays have a friction trip operating mechanism with loss of phase running protection, pull back spring trip operating mechanism (jump mechanism) with loss of phase protection for T85 & TSA45, backpack jump
mechanism for T170 & T105, main circuit with instrument transformer jump mechanism with loss of phase for T250 & T370
3UA
3UA thermal relay is suitable for using in power system with AC 50Hz, rate operation voltage up to 660V and 1000V, in main circuit, current from 0.1A to 630A. It is used to protect AC three-phase asynchronous motor against overload and open-phase. The current setting value can be regulated and the setting current values of many thermal elements are intercrossing overlapping arrangement, for easy selecting by the customers from -25℃ to +55℃ air temperature as the products have temperature compensating. The relays have the test push-button for breaking NC contacts, the operating indications and free trip characteristics. The items conform to IEC60947-4.
LR1
LR1-D series thermal relay is suitable for thermal protection in the circuit with AC 50or 60Hz, voltage up to 660V, motor power up to 45KW or less. It has differential attachment and automatic temperature-compensating function. It can be fixed on to contactor and canalso be fixed independently.
The product is made in accordance with IEC60947-4
TH-K/N
The thermal overload relays are suitable for overload protection of AC motor operated on 8-hours duty or uninterrupted duty.
The overload protecting AC motor with frequency 50Hz, voltage up to 660V, current up to 40A.
Serval functions provided by these relays are phase-failure protection, temperature compensation, ON/OFF indication and manual/automatic reset. The relays comply with IEC60947-4 standard.
