These circuit protectors are available in 1, 2, 3 and 4 pole models, with a choice of handle colors with on/off and international I/O markings. These protectors comply with UL and CSA standards and meet IEC and VDE spacing requirements. Typical applications include computers and 161 IELR Series - Introduction peripherals, telecommunications, medical equipment, machine tools and process control instrumentation. They provide the reliable performance associated with magnetic circuit protection. Mounting - These circuit protectors are designed to mount on standard 35mm DIN rails, such as 35x7.5 or 35x15 per DIN EN50022. Other specialty rails are available from suppliers that provide a means of mounting non DIN mount components by means of special captive jam nuts. http://airpax.sensata.com IELR (Rail-Mount) Single Pole 1.929 [49.00] .236 [5.99] .138 [3.51] DIM.iAi .183 [4.65] .689 [17.50] .689 [17.50] 1.680 [42.67] 1.122 [28.50] 1.417 [35.99] ON 1.437 [36.50] 2.500 [63.50] 3.622 [92.00] I OFF 2.059 [52.30] O 2 X 6-32 THREAD M3 X 0.5-6H THREAD OPTIONAL .142 [3.6] DEEP (TYP.)

The handle position conveniently indicates circuit status. In addition to providing conventional overcurrent protection, it's simultaneously used as an on-off switch. Series Switch Only In the event that over-current protection is not desired, the coil mechanism can be deleted, providing an excellent low cost, single or multi-pole power switch. Insulation Resistance 100 megohm minimum at 500Vdc between all electrically isolated terminals. Dielectric Strength 3750Vac (3750V~) shall withstand AC voltages 50/60Hz for 60 seconds between all electrically isolated terminals. LINE LOAD Switch Only Endurance Circuit breakers shall operate a minimum of 10,000 operations; 6,000 with rated current and voltage and 4,000 with no load. Operating Temperature -40C to +85C.

IELR Series - Operating Characteristics 164 IELR DELAY CURVES 400Hz, DC, 50/60Hz Delay Curves (typ) A choice of delays is offered for DC, 50/60Hz, 400Hz, or combined DC/50/60Hz applications. Delays 49, 59, 69 and 79 provide fast acting, instantaneous tripping and are often used to protect sensitive electronic equipment (not recommended where a known inrush exists). Delays 41, 51, 61 and 71 have a short delay for general purpose applications. Delays 42, 52, 62 and 72 are long enough for most transformers and capacitor loads. Delays 43, 53, 63 and 73 are extra long for special motor applications. 50/60Hz Delay Curves (typ) 10000 10000 DELAY 61 1000 100 10 TIME IN SECONDS MAY TRIP TIME IN SECONDS 100 1 10 1 .1 .1 .01 .01 .001 .001 0 100 150 200 125 300 400 500 600 700 800 900 1000 0 PERCENT OF RATED CURRENT 300 400 500 600 700 800 900 1000 900 1000 10000 DELAY 62 1000 DELAY 69 1000 MAY TRIP TIME IN SECONDS 100 10 1 10 1 .1 .1 .01 .01 .001 MAY TRIP 100 TIME IN SECONDS 100 150 200 125 PERCENT OF RATED CURRENT 10000 .001 0 100 150 200 125 300 400 500 600 700 PERCENT OF RATED CURRENT 165 DELAY 63 MAY TRIP 1000 IELR Series - Delay Curves 800 900 1000 0 100 150 200 125 300 400 500 600 700 800 PERCENT OF RATED CURRENT http://airpax.sensata.com IELR (Rail-Mount) DC Delay Curves (typ) DELAY 51 1000 1000 TIME IN SECONDS 10 1 10 1 .1 .1 .01 .01 .001 .001 0 100 150 200 125 300 400 500 600 700 800 900 0 1000 PERCENT OF RATED CURRENT 10000 100 150 200 125 300 400 500 600 700 800 900 1000 900 1000 PERCENT OF RATED CURRENT 10000 DELAY 52 MAY TRIP 100 TIME IN SECONDS 100 10 1 10 1 .1 .1 .01 .01 .001 0 100 150 200 125 DELAY 59 1000 300 400 500 600 700 PERCENT OF RATED CURRENT 800 900 1000 MAY TRIP 1000 TIME IN SECONDS DELAY 53 100 MAY TRIP TIME IN SECONDS 100 MAY TRIP 10000 10000 .001 0 100 150 200 125 300 400 500 600 700 800 PERCENT OF RATED CURRENT IELR Series - Delay Curves 166 DC/50/60Hz Delay Curves (typ) (Multi-Frequency) 10000 10000 100 TIME IN SECONDS TIME IN SECONDS 100 1000 10 1 10 1 .1 .1 .01 .01 .001 DELAY 73 DC/50/60 Hz Motor Start Delay MAY TRIP MAY TRIP 1000 DELAY 71 DC/50/60 Hz Short Delay .001 0 100 150 200 135 300 400 500 600 700 800 900 1000 0 100 150 200 135 300 PERCENT OF RATED CURRENT 10000 MAY TRIP 600 700 800 900 1000 900 1000 DELAY 79 DC/50/50 Hz 135% Instant Trip 1000 100 10 1 10 1 .1 .1 .01 .01 .001 MAY TRIP TIME IN SECONDS 100 TIME IN SECONDS 500 10000 DELAY 72 DC/50/60 Hz Long Delay 1000 .001 0 100 150 200 135 300 400 500 600 700 PERCENT OF RATED CURRENT 167 400 PERCENT OF RATED CURRENT IELR Series - Delay Curves 800 900 1000 0 100 150 200 135 300 400 500 600 700 800 PERCENT OF RATED CURRENT http://airpax.sensata.com IELR (Rail-Mount) 400Hz Delay Curves (typ) 10000 DELAY 41 10 1 10 1 .1 .1 .01 .01 .001 .001 0 100 150 200 125 300 400 500 600 700 800 900 1000 0 PERCENT OF RATED CURRENT 100 150200 125 300 400 500 600 700 800 900 1000 900 1000 PERCENT OF RATED CURRENT 10000 10000 DELAY 42 MAY TRIP 100 TIME IN SECONDS 100 DELAY 49 1000 10 1 10 MAY TRIP 1000 TIME IN SECONDS DELAY 43 100 TIME IN SECONDS 100 TIME IN SECONDS 1000 MAY TRIP 1000 MAY TRIP 10000 1 .1 .1 .01 .01 .001 .001 0 100 150 200 125 300 400 500 600 700 PERCENT OF RATED CURRENT 800 900 1000 0 100 150 200 125 300 400 500 600 700 800 PERCENT OF RATED CURRENT IELR Series - Delay Curves 168 AGENCY APPROVALS Voltage (Volts) Rated Current (Amps) Max Voltage Frequency (Hz) Phase Min Poles 80 DC -- 80 DC -- 250 50/60 1&3 Interrupting Capacity, Amps UL/CSA VDE UL1077 & CSA VDE 1 .05 to 50 .10 - 50 u2, 1000 4000 1 .05 to 100 -- u2, 5000 -- 1 .05 to 50 .10 - 50 3500 2000 250 50/60 1&3 1 .05 to 70 -- 2000 -- 250 50/60 1&3 1 .05 to 50 -- 5000 (1) -- 250 50/60 1&3 1 .05 to 70 -- 5000 (1) -- 277 50/60 1 1 .05 to 50 -- 2000 -- 277 50/60 1 1 .05 to 50 -- 5000 (1) -- 240/415 50/60 1&3 2 .05 to 50 .10 - 30 2000 2000 240/415 50/60 1&3 2 .05 to 50 -- 5000 (1) -- 277/480 50/60 3 2 .05 to 30 -- 2000 -- 250 400 1&3 1 .05 to 50 -- 1750 -- Note: (1) with 125A max series fuse. IELR DECISION TABLES How to Order The ordering code for IELR circuit protectors may be determined by following the steps in the decision tables shown here. The coding given permits a self-assigning part number, but with limitations. Using the illustrated coding system, it will automatically be assumed that all poles are identical. When all poles of a multi-pole protector are not identical, please contact an Airpax sales representative or the factory for a part number. One great virtue of magnetic circuit protectors is their adaptability to complex circuits. Thus, variations from pole to pole can become the rule rather than the exception. Descriptive drawings are recommended to avoid confusion. Notes: When poles are not identical, each pole is to be described and a special Airpax number will be assigned. Thomas & Betts (T&B) Narrow Tongue Lug P/N 54108NT is recommended for units rated above 50A. The T&B lug or an equivalent must be used on units rated 70A and above. When specifying a protector for AC motor start or high inrush applications, it is helpful to know the peak amplitude and surge duration for proper protector selection. 169 IELR Series - Approvals & Decision Tables http://airpax.sensata.com 5 First Decision Type Fifth Decision Rated Current IALHR One handle per pole (multi-pole only) IULHR One handle per pole (multi-pole only) UL Recognized, CSA Certified and VDE Approved ratings .100 10.0 .250 15.0 .500 20.0 One handle per pole (multi-pole only) UL Recognized, CSA Certified and VDE Approved ratings .750 30.0 1.0 35.0 2.5 40.0 5.0 50.0 7.5 60.0 IELHR IALR One handle per unit IULR One handle per unit UL Recognized and CSA Certified ratings IELR One handle per unit UL Recognized, CSA Certified and VDE Approved ratings IMLR Mid-trip indication, One handle per unit IMLHR Mid-trip indication, One handle per pole 2 Standard ratings listed.
