West Control Solutions TB 40-1 Temperature Limiter - Manual (Page 26)

Contact type: 2 NO contacts with common
connection
Max. contact rating: 500 VA, 250 V, 2A at 48...62 Hz,
resistive load

Note:
If the relays OUT1...OUT LC operate external
contactors, these must be fitted with RC
snubber circuits to manufacturer specifications
to prevent excessive switch-off voltage peaks.
