Each of these applications has one common factor: a steep transient of very high current amplitude and short duration. This takes the form of a spike or a single pulse and is the cause of most nuisance tripping associated with magnetic circuit breakers. The IAR/IUR/IER/CUR/CER series will withstand, without tripping, a single pulse of 8 milliseconds duration (half sine wave configuration) and peak amplitude of 10 times its rating.

Handle color is black with white markings, and is has been met all the selection criteria to obtain the TÜV approval. 1 First Decision First Choice: Type IAR Magnetic circuit protector, one handle per unit IARH Magnetic circuit protector, one handle per pole K 10-32 stud terminal IER UL1077 & TÜV, series trip, one handle per unit B 0.250” bullet terminal IERH UL1077 & TÜV, series trip, one handle per pole IUR UL1077, series trip, one handle per unit IURH UL1077, series trip, one handle per pole IMR UL1077 & TÜV, mid trip, one handle per unit IMRH UL1077 & TÜV, mid trip, one handle per pole CER UL489A & TÜV, series trip, one handle per unit CERH UL489A & TÜV, series trip, one handle per pole CUR UL489A, series trip, one handle per unit CURH UL489A, series trip, one handle per pole CMR UL489A & TÜV, mid trip, one handle per unit CMRH UL489A & TÜV, mid trip, one handle per pole To determine the ordering code for your particular unit, simply follow the steps shown, then fill in the letters and/or numbers in the boxes. Space is available on the circuit breaker label for your part number (up to 12 digits). You may then use your own part number to place an order or as a reference for further questions you may have. This option does require a factory assigned part number for traceability to your drawing or internal part number. 57 Second Choice: Terminal IAR/IUR/IER/CUR/CER Series - Decision Tables 10-32 screw terminal, standard (no entry) The shaded areas denote TÜV approval options. This approval requires the addition of a “T” at the end of the part number (8th decision). The “T” will automatically be added to any part number formed entirely from these shaded decisions. If non-shaded areas are selected, the unit will not be TÜV approved, but other approvals (if applicable) will still apply. IER 1 - 1REC4C - 52 - 20.0 - AD - 01 - T 1 2 2 Second Decision 3 4 5 6 7 8 TÜV Approval Per first decision’s description: The shaded areas denote TÜV approval options.
