JRS5 series thermal overload relayDetailed product description：

1、 Scope of application
The JRS5 (TH-K) and JRS6 (TH-N) series thermal overload relays are suitable for overload protection of general AC motors that operate for a long time or intermittently for a long time, with AC 50 or 60Hz, voltage up to 660V, and current up to 105A. This thermal relay has functions such as phase failure protection, temperature compensation, and trip indication, and can automatically and manually switch positions with reliable operation. It is a product manufactured by Mitsubishi Corporation in Japan.

3、 JRS5 series thermal overload relay action characteristics

serial number	The action current is expressed in multiples of the set current		Action time (TP)	work status	Environmental temperature (℃)
one	one		＞2h	Cold state begins	+55
	one point zero five				+20. -5
two	one point two		＜2h	Hot state begins	+20. +55
	one point three				-5
three	one point five			Hot state begins	+20
four	seven point two zero			Cold state begins	+20
Note: Hot state - start heating with the corresponding current in item 1 until stable
serial number	The action current is expressed in multiples of the set current		Action Time	work status	Environmental temperature (℃)
	Any two phases	Third phase			+20
one	one	<āDIV align=center>0.9	＞2h	Cold state begins
two	one point one five	0	＜2h	Hot state begins
