| Jun 16, 2015 at 19:11 | comment | added | Danny Beckett | Thanks for your help everyone. Hopefully we can find a replacement relay in the RS catalogue that will do the job. Presumably as long as the number of pins, total voltage, current, and coil voltage are the same - it should be fine to swap them out. He's going to call an electrician in anyway. Cheers guys - someone want to write an answer? | |

| Jun 16, 2015 at 19:05 | comment | added | Spehro 'speff' Pefhany | @DannyBeckett LOL. Okay. Maybe he should get an industrial electrician in. By 'maybe' I mean definitely. | |
| Jun 16, 2015 at 19:04 | comment | added | Danny Beckett | @SpehroPefhany He pushed a screwdriver into the slot to test them both, about half an hour ago, but there was a massive bang and the fuses blew. He doesn't know which one made it blow and doesn't want to do it again for obvious reasons. | |
| Jun 16, 2015 at 19:03 | comment | added | Spehro 'speff' Pefhany | P.S. Overload relay is the correct search term for the other unit, as @brhans said. The other parts are industrial contactors. Newer units won't look that much different. | |
| Jun 16, 2015 at 18:56 | comment | added | Spehro 'speff' Pefhany | The contactors have a place to push to actuate but the person doing the testing must know that it won't cause anything undesirable to happen. | |
| Jun 16, 2015 at 18:53 | comment | added | Danny Beckett | @brhans How can we test both of the relays to see which has failed? Thanks again for your help!! | |
| Jun 16, 2015 at 18:51 | comment | added | Danny Beckett | The question now is how to make sure we buy the right relay? He's worried that we will wire it up wrong and blow something. | |
| Jun 16, 2015 at 18:51 | comment | added | brhans | As WRB says, 'contactor' is the term used for these large 3-phase devices which we in the electronics world would usually call a relay. Does much the same job, but on a larger scale. The addon device with the knob on it is the 'overload relay' and it causes the large contactor its attached to to 'trip' when it senses excess current flow. | |
| Jun 16, 2015 at 18:51 | comment | added | Danny Beckett | @WhatRoughBeast That makes sense! | |
| Jun 16, 2015 at 18:46 | comment | added | WhatRoughBeast | @DannyBeckett - Contactor is just a name for a high-current relay. | |
| Jun 16, 2015 at 18:45 | comment | added | Danny Beckett | @brhans 'Contactors' is what my friend is calling them actually. This is all he knew about it. I hadn't heard of them before, so thought he might've meant a relay. He said he thinks there is a coil in it. He thinks this is the component that's failed because otherwise the only other components are the toggle switch (which he's replaced) and a fuse (which he's tested). When toggling the switch, it occasionally isn't doing anything (stuck as if it's in the middle off position). Thanks! | |
| Jun 16, 2015 at 18:42 | comment | added | Danny Beckett | @SpehroPefhany After checking with my friend again, he said it probably is more like 60's. It is English made. You're right, it is 3-phase. | |
| Jun 16, 2015 at 18:40 | comment | added | Danny Beckett | @LorenzoDonati I've edited the question to add more detail, thanks. | |

| Jun 16, 2015 at 18:37 | comment | added | brhans | And each contactor seems to have a set of auxiliary contacts fitted to the top - can't be sure from that angle though. | |
| Jun 16, 2015 at 18:36 | comment | added | brhans | That looks like a pair of old contactors with an overload relay fitted to one of them. What makes you think one of these has failed? | |
| Jun 16, 2015 at 18:34 | comment | added | Spehro 'speff' Pefhany | That's an oddball- looks older than the 1980s- 1960s more like, to me anyway. Is it of European origin? Maybe an adjustable 3-phase (?) circuit breaker. The parts below the mystery device appear to just be industrial contactors (not much different now from then). | |
| Jun 16, 2015 at 18:34 | comment | added | LorenzoDonati4Ukraine-OnStrike | What's the purpose of the machine in which those components are placed? | |
