Folks,
Here's an old thread with exactly the same question that I have now:
http://www.practicalmachinist.com/v...pulse-type-p25-tp-10h-2-3-2amp-switch-110981/
That thread says that there is a switch of this type on the Charmilles EDM machine.
This switch was originally made by Carl Maier & Cie (CMC) in Switzerland but was bought in 1992 by ABB. "CMC" in this case is not Cleveland Motion Controls. I have contacted ABB both in the US and in Switzerland but to no avail. I've found these switches on ebay but not with the correct current spec which is 2 - 3.2 A. This switch has thermal overload breakers inside and a spring loaded switch. It trips and stays tripped until it's "ready" to be switched back on. I can find lots of 3-pole cam switches but none with the breakers. I'm searching Siemens and Schneider for something similar but I'm not there yet and in any case their switches will not have nearly the form factor I want. It is a 3-pole single throw switch. Voltage at the poles is 240V shown on my Fluke 79 DVM and my guess is the switch is used to energize a motor relay (wires are small). This switch trips after a couple minutes of motor operation with no machine load on the motor (belt off). I have another identical machine from which I took its switch and substituted and the substitute does not trip. I would like to find a replacement for the "tripper."
Ideally I would find a new (old stock, perhaps) or used original.
This switch is integral to a Güdel (Swiss) special engraving machine built in 1978. The machine is built to operate with 220V 3ph.
Perhaps those of you that live in Europe might have a handle on a source. The "Tp 10h" seems to be a key designator for this switch as Google recognizes it.
Here are the numbers on the switch:
CMC
Tp 10h 2-3,2 amp (is this adjustable??)
T25A max. 500V 10A VDE 0600
8hp max. 600V ac 3ph
Part number:~ E-NO 500 140 xxx
Body diameter ~60mm
Here are pictures of the switch and the machine. Any help with a source would be greatly appreciated.
(This is the right switch but the current rating is not what I need)
