LR-power relay the power relay LR LR relays are power relays which convince by her brilliant simplicity. The mature and simple construction will predestine this relay for the rough and uncompromising use. By using best materials and because of the simple construction a max. mechanical and electrical life time was achieved. The special advantages of this mature relay lie in the high switching power as well as in the low power consumption of the coil. The LR relay is available in AC- and also in DC- version features applications • • • • • • switching of short-circuit runner engines • radiators in household appliance • radiators in electromechanical ovens simple construction high switching power low coil power extraordinary life time DIN rail mountable 28 catalog 2002 e / 04.03 type number key LR 024 VDC coil voltage VDC = direct current VAC = alternating current standard voltage VAC: 024, 230 V VDC: 024, 110 relay version LR order sample LR 230 VAC - 3 normally open contacts coil voltage 230 VAC AMP connections DIN-rail installation catalog 2002 e / 04.03 29 LR - power relay Power relays especially for switching high AC- loads. order numbers serial version LR 220 VAC LR 24 VDC contact specifications (see data sheet for curves) contact material contact type nominal switching capacity AgCdO single contact 250 VAC 20A AC1 5000 VA 400 VAC 15A AC1 app. 900'000 operations 250 VAC 20A AC1 (360 Schaltung/h) 50A for 200 ms 500mA to 20A 8VA(W) to 5000VA electric life expectancy inrush current max. switching current range switching power range general data max. switching frequency mechanical mechanic life expectancy pull-in time release time bounce time shock resistance test voltage, coil/contact test voltage, open contact insulation resistance weight installation situation ambient temperature max. 15 20 Mio. 13 ms (VDC) /6-14 ms (VAC) 2,5 ms (VDC) /3-12 ms (VAC) 2 ms (VDC) /3 - 8 ms (VAC) AK: 10 g 2’500 Veff 2’500 Veff >1012 Ohm 120 g any +60 °C tests, instructions certificates insulation group 30 catalog 2002 e / 04.03 CSA, VDE VDE 0110 / group C 250 VAC 2 1 a 2 4 3 4 3 b 6 b 6 1 a 5 5 circuit diagram AMP connection side 5 55 dimensions 4, 5 20 16 0,8x6,3 42 52 42 44 ø 4,5 coil specifications standard coils for direct current (other voltages on enquiry) energizing voltage range 3,0 rated voltage VDC pull-in voltage at 20 °C reset voltage at 20 °C nominal current mA resistance Ohm at 20 °C tolerance % 12 9 ≥ 0,6 114 105 +/-10 24 18 ≥ 1,2 58,5 410 +/-10 48 36 ≥ 2,4 30,0 1'600 +/-10 110 82,5 ≥ 5,5 13,8 8'000 +/-10 2,5 2,0 UB UN 1 1,5 1,0 2 0,5 0 20 40 60 80 100 ambient temperature °C DC-relay AC-relay - single relay, no heat concentration by surrounding components with self-heating. - on time 100% 1) max. energizing voltage without contact load 2) min. energizing voltage (guaranteed value), without operation in advance. standard coils for alternated current (other voltages on enquiry) VAC 12 10,2 ≥ 0,6 260 10 +/-10 24 20,4 ≥ 1,2 130 40 +/-10 48 40,8 ≥ 2,4 60 180 +/-10 110 93,5 ≥ 5,5 29 950 +/-10 220 187 ≥ 11 14 3'900 +/-10 catalog 2002 e / 04.03 31 LR - contact specifications AgCdO data valid for relay contact material contact type nominal switching capacity Ι [A] max.
