IAL/CEL/LEL SERIES HYDRAULIC MAGNETIC CIRCUIT PROTECTORS Introduction IAL/IUL/IEL/LEL magnetic circuit protectors provide low-cost power switching, reliable circuit protection and accurate circuit control for equipment in the international marketplace. IAL models are for those applications where the units inherent attributes are desired, but compliance with the various standards is not required. IUL models have been tested and approved in accordance with UL 1077 requirements for UL recognition. IEL/LEL models are TUV approved to IEC 60947-2. They meet IEC spacing requirements, mandatory for equipment which must comply with IEC specifications. In addition, the IEL models are UL recognized to UL 1077 as supplementary protectors and the LEL models are UL listed under the conditions of UL 489. Both are CSA certified and CCC Approved. The IEL is CSA certified as a supplementary protector per CSA C22.2No. 235. The CEL model has achieved two new enhancements, including a single pole, 125 amp rating with TV approval, and a parallel 4-pole version with 400 amp rating. Airpax IAL/CEL/LEL circuit protectors are available in a wide variety of configurations, including series, series with auxiliary switch, shunt and relay with choice of delays and ratings in DC and/or 50/60Hz or 400Hz versions. Single or multi-pole versions are available with a variety of pole arrangements to meet your specifications. Please see the appropriate product specification table for ratings and limitations.

C Stud terminals are supplied with a flatwasher, external tooth lockwasher and a 10-32 or M5 hex nut (<=70A) (<=50A for LEL),1/4-20 or M6 hex nut (>70A)(>50A for LEL). Bullet terminal receptacle should be .312 .001 diameter hole not less than .250 depth. Contact Sensata for other bullet sizes. Each outer terminal is supplied with a flatwasher, tooth lockwasher and a hex nut. MULTI-POLE CIRCUIT PROTECTORS Multi-pole units are combined in an assembly with the trip mechanisms internally coupled. A fault in any protected circuit opens all poles simultaneously. Applications include use in polyphase circuits, single-phase three-wire systems, or in two or more related but electrically isolated circuits. A mix of delays, ratings and configurations are offered. The auxiliary switch is offered with either gold or silver contacts and is available when a series construction pole is specified. Two Pole An assembly consisting of two single pole units, having their trip mechanisms internally coupled, is available with either a single toggle handle or with a handle per pole. Please see decision one of the part number decision tables. Individual poles may vary in ratings, delays and internal configurations. If the poles are of series construction, an auxiliary switch may be included in either or both poles, allowing you to mix SEL V and hazardous voltages.
