Product questions
What contact configuration does ABB 1SAE901901R1011 have?
The EH04-11N has one normally open and one normally closed auxiliary contact, with two poles and no main contacts.
Which contactors can the EH04-11N auxiliary contact block be used with?
The published data lists ESB16..N, ESB20..N, ESB25..N, ESB40..N, ESB63..N, ESB100..N, EN20..N, EN25..N and EN40..N installation contactor series. For any other contactor, provide its complete model and serial number to verify fitment.
How does the EH04-11N mount and connect?
The block mounts on the left side of a compatible contactor without tools and uses screw terminals for its auxiliary connections.
Is the EH04-11N rated for 6 A at every voltage and load?
No. Its 6 A rating is the conventional free-air thermal current, not a universal switching rating. For example, the stated operational ratings are 3 A at 415 V AC for AC-15 and 0.55 A at 125 V for DC-13. Select for the actual load and voltage.
