IELR Series - Poles 162 IELR (Rail-Mount) IELR SPECIFICATIONS Series Trip Series LINE The most popular configuration for magnetic protectors is the series trip where the sensing coil and contacts are in series with the load being protected. The handle position conveniently indicates circuit status. In addition to providing conventional overcurrent protection, it’s simultaneously used as an on-off switch. Switch Only LOAD 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. Switch Only Dielectric Strength 3750Vac (3750V~) shall withstand AC voltages 50/60Hz for 60 seconds between all electrically isolated terminals. 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 –40°C to +85°C. IEC 144 Classification Type handle spacings–IP40. Terminals–IP00. Moisture Resistance 10 days, 95 percent relative humidity at 40°C in accordance with Three Pole Schematic Diagram IEC68-2-3, test C. Salt Spray Five percent solution at 35°C in accordance with IEC68-2-11, test K, 48 hours. Shock 50g, 11m sec, half sine with rated current, except no current with handle down. Instantaneous units use 80 percent rated current. Test in accordance with IEC68-2-27, test Ea. This assumes that adequate end stops are used to prevent longitudinal movement of the circuit protector.

IELR Series - Operating Characteristics 164 IELR (Rail-Mount) 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 1000 1000 DELAY 61 DELAY 63 100 100 10 10 1 1 .1 .1 .01 .01 .001 .001 0100 150 200 300 400 500 600 700 800 900 1000 0100 150 200 300 400 500 600 700 800 900 1000 125 125 PERCENT OF RATED CURRENT PERCENT OF RATED CURRENT 10000 10000 1000 DELAY 62 1000 DELAY 69 100 100 10 10 1 1 .1 .1 .01 .01 .001 .001 0100 150 200 300 400 500 600 700 800 900 1000 0100 150 200 300 400 500 600 700 800 900 1000 125 125 PERCENT OF RATED CURRENT PERCENT OF RATED CURRENT IELR Series - Delay Curves 165 http://airpax.sensata.com TIME IN SECONDS TIME IN SECONDS MAY TRIP MAY TRIP TIME IN SECONDS TIME IN SECONDS MAY TRIP MAY TRIP DC Delay Curves (typ) 10000 10000 1000 1000 DELAY 51 DELAY 53 100 100 10 10 1 1 .1 .1 .01 .01 .001 .001 0100 150 200 300 400 500 600 700 800 900 1000 0100 150 200 300 400 500 600 700 800 900 1000 125 125 PERCENT OF RATED CURRENT PERCENT OF RATED CURRENT 10000 10000 1000 1000 DELAY 52 DELAY 59 100 100 10 10 1 1 .1 .1 .01 .01 .001 .001 0100 150 200 300 400 500 600 700 800 900 1000 0100 150 200 300 400 500 600 700 800 900 1000 125 125 PERCENT OF RATED CURRENT PERCENT OF RATED CURRENT IELR Series - Delay Curves 166 TIME IN SECONDS TIME IN SECONDS MAY TRIP MAY TRIP TIME IN SECONDS TIME IN SECONDS MAY TRIP MAY TRIP IELR (Rail-Mount) DC/50/60Hz Delay Curves (typ) (Multi-Frequency) 10000 10000 DELAY 71 DELAY 73 DC/50/60 Hz 1000 1000 DC/50/60 Hz Short Delay Motor Start Delay 100 100 10 10 1 1 .1 .1 .01 .01 .001 .001 0100 150 200 300 400 500 600 700 800 900 1000 0100 150 200 300 400 500 600 700 800 900 1000 135 135 PERCENT OF RATED CURRENT PERCENT OF RATED CURRENT 10000 10000 DELAY 72 DELAY 79 1000 DC/50/60 Hz 1000 DC/50/50 Hz Long Delay 135% Instant Trip 100 100 10 10 1 1 .1 .1 .01 .01 .001 .001 0100 150 200 300 400 500 600 700 800 900 1000 0100 150 200 300 400 500 600 700 800 900 1000 135 135 PERCENT OF RATED CURRENT PERCENT OF RATED CURRENT IELR Series - Delay Curves 167 http://airpax.sensata.com TIME IN SECONDS TIME IN SECONDS MAY TRIP MAY TRIP TIME IN SECONDS TIME IN SECONDS MAY TRIP MAY TRIP 400Hz Delay Curves (typ) 10000 10000 1000 DELAY 41 1000 DELAY 43 100 100 10 10 1 1 .1 .1 .01 .01 .001 .001 0100 150 200 300 400 500 600 700 800 900 1000 0100 150200 300 400 500 600 700 800 900 1000 125 125 PERCENT OF RATED CURRENT PERCENT OF RATED CURRENT 10000 10000 1000 DELAY 42 1000 DELAY 49 100 100 10 10 1 1 .1 .1 .01 .01 .001 .001 0100 150 200 300 400 500 600 700 800 900 1000 0100 150 200 300 400 500 600 700 800 900 1000 125 125 PERCENT OF RATED CURRENT PERCENT OF RATED CURRENT IELR Series - Delay Curves 168 TIME IN SECONDS TIME IN SECONDS MAY TRIP MAY TRIP TIME IN SECONDS TIME IN SECONDS MAY TRIP MAY TRIP IELR (Rail-Mount) AGENCY APPROVALS Voltage (Volts) Rated Current (Amps) Interrupting Capacity, Amps Max Voltage Frequency (Hz) Phase Min Poles UL/CSA VDE UL1077 & CSA VDE 80 DC — 1 .05 to 50 .10 - 50 u2, 1000 4000 80 DC — 1 .05 to 100 — u2, 5000 — 250 50/60 1 & 3 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.

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. 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.
