Features

The Airpax™ IAR/IUR/IER/CUR/CER series is a snap-acting hydraulic-magnetic circuit breaker / protector that combines power switching and accurate, reliable circuit protection in one aesthetically pleasing, “1U” or “1RU” sized package. Designed for rack mount applications, the IAR/IUR/IER/CUR/CER series allows efficient use of rack space without sacrificing performance via proven hydraulic-magnetic technology that provides consistent operation from -40°C to 85°C, with a circuit interrupt capacity up to 5,000 AIC at 80VDC and 2,000 AIC at 250VAC. Available in series trip and mid-trip configurations, with auxiliary alarm switch options to provide monitoring of critical circuits. The CER series circuit breaker provides the necessary ratings for wireless and wired applications while meeting UL489A and TÜV requirements for approval.

CONFIGURATIONS The most popular configuration for magnetic protectors is the series trip where the sensing coil and the contacts are in series with the load being protected. In addition to providing conventional overcurrent protection, it is simultaneously used as an on-off switch. This is furnished as an integral part of a series pole in single or, multi-pole assemblies. Isolated electrically from the protectors circuit, the switch works in unison with the power contacts and provides indication at a remote location of the protector’s ON-OFF status.

DELAY CURVES & SPECIFICATIONS OPERATING CHARACTERISTICS DC, 50/60Hz Delay Curves (typ) A choice of delays is offered for DC and 50/60Hz applications. Delays 59 and 69 provide fast-acting, instantaneous trip and are often used to protect sensitive electronic equipment (not recommended where known inrush exists). Delays 51 and 61 have a short delay for general purpose applications. Delays 52 and 62 are long enough to start certain types of motors and most transformer and capacitor loads. Trip Free Will trip open on overload, even when forcibly held on. This prevents operator from damaging the circuit by holding handle in the ON position. Trip Indication The operating handle moves forcibly and positively to the OFF position on overload. Ambient Operation Operates normally in temperatures between –40° C and +85°C. Insulation Resistance Not less than 100 megaohms at 500Vdc. Dielectric Strength Shall withstand AC voltage 60 Hz, for 60 seconds between all electrically isolated terminals as described below Series, switch only: 3,750 VAC Auxiliary switches: 600 VAC Series w/ auxiliary switch: 3,750 between main circuit breaker terminal and auxiliary switch terminal. Shock Shall not trip when tested per MIL-STD-202, method 213, test condition 1 with 100% rated current applied to delayed units, except 90% current in plane 4, (i.e. handle down). Instantaneous units shall have 80% rated current applied in all planes. Vibration Shall not trip when vibrated per MIL-STD-202, method 204, test condition A with 100% rated current applied to delayed units and 80% rated current to instantaneous units. Endurance In many applications contact wear due to the electrical load determines unit life. At maximum electrical ratings, the IAR/UR/IER/CUR/CER can per- form 10,000 operations at rated current and voltage at a maximum rate of 6 operations per minute. Inrush Pulse Tolerance Many circuit protector applications involve a transformer turn-on, an incandescent lamp load, or a capacitor charge from a DC source. 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.

In addition to full ON and full OFF positions, there is a middle “MID-TRIP” position indicating that the breaker has electrically tripped from an overload. It is available in single pole and multi-pole (handle per pole only) series constructions. Switch only configuration is not available in mid-trip build. An auxiliary switch can be furnished as an integral part of the mid-trip breaker. The switch provides an indication at a remote location when the circuit breaker has electrically tripped and handle is in the mid-trip position.

The example shown is the code for a UL1077 & TÜV approved circuit protector with series trip, one handle per unit, single pole circuit protector with 10-32 terminal screws standard and a mechanical auxiliary switch. This unit is designed with a slow DC time delay and a rating of 20 amperes with optional metric threads and optional 80VDC capability. Handle color is black with white markings, and is has been met all the selection criteria to obtain the TÜV approval. 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.
