One spring is for the cut in pressure and the other is for the cut out pressure. I did not adjust the trip settings when I first started on this. Usually I will do: LT @ 1x with a delay anywhere from 10-20 ST @ 4x and 0.3 out INST @ 8x GF @ 0.25x and 0.3 out I find these setting work just â¦ Typical pressure settings for a low-pressure system will be a cut in (start pressure) of 20 PSI and a cut out (stop pressure) of 40 PSI. â Micrologic 1.3 M trip units (L-frame only) provide short-circuit protection of motor-feeders. AC-PRO is UL and ULC classified for use on the following low voltage AC power circuit breakers: Westinghouse DB-50 Square D/Westinghouse DS-206, DS-416, â¦ For example, newer Siemens breakers warn the user (in the manual) not to adjust setting with the breaker energized. Easy online ordering for the ones who get it done along with 24/7 customer service, free technical support & more. The magnetic element of each pole of the trip unit can be adjusted by rotating the adjustment buttons on the front face of the trip unit with a screwdriver. This is an adjustable INSTANTANEOUS so the trip ranges are from 800 amps to 1500 amps or 5.33 times 150 amps to 10 times 150 amps. üÁ¼y'gö¹µ&ðìÃÏªÀGcµe¾y|«±,/¸6*Ü+¤zÇ²¸ÜK©µãÌg±¹¿òÝYÏØÀLJ®aF¯½{ë'à®í[û&¬û¸óøZðë.£f ëøÞ^5xdód`õ¿v^ÒÖ0>ÆKXä&µLQ*±O¬hª2±*QÃ"' ûDq"c¤ ûãI&¤A&JU!ÅHR%ë$4&Öd_¡1±®0¿¶¶Lù«÷1z|nÌ|KÛXHÝ¶ÅãÇ~íIÍ endstream endobj 213 0 obj << /DescendantFonts [ 233 0 R ] /BaseFont /TQASYH+Arial-ItalicMT /Type /Font /Encoding /Identity-H /Subtype /Type0 /ToUnicode 212 0 R >> endobj 214 0 obj << /Filter /FlateDecode /Length 211 0 R >> stream Marketing Trade Name Square D AC Magnetic Trip Setting 750A - 1500A Frame Type K-Frame HACR Rated Yes Voltage Rating 600VAC Weight 7 Pounds Mounting Type Unit Mount Number of Poles 3-Pole Short Circuit Current Rating 25kA@480VAC Space Required 3 Type KA Wire Size (1)#4 to 350 AWG/kcmil(Al/Cu) Width 4.50 â¦ the 3rd trip.
