1 description typical applications ordering information approvals technical data (t a = 25 c, u e = dc 28 v or ac 115v/400 hz) single pole remote control circuit breaker (rccb), temperature compensated, either with or without auxiliary contacts, and featuring a bimetal actuator which trips the circuit breaker mechanism within a specified time under overcurrent conditions. the switching contact latching system is operated by a bi-stable linear motor controlled by electronic circuitry incorporated within the device. remote control is achieved through the use of a conventional single pole manually operated aircraft style thermal circuit breaker type 4120-0,5 a which connects the control input of the rccb to ground. with the control circuit breaker (icu) in the on position, the rccb will switch on. when the control circuit breaker is switched off, the rccb will change to the off condition. if power is applied to a previously de-energised rccb, the device will adopt the same switching status as the control circuit breaker. if the rccb trips thermally in the event of a load circuit fault, the electronic circuitry will also cause the control circuit breaker to trip, thereby providing a visual indication through the position of the circuit breaker actuator. approved to mil-prf-83383. aircraft electrical systems and equipment, and other high performance applications. 4930 (rccb) type no. 4930 single pole remote control circuit breaker (rccb) variation 01 standard, with auxiliary contacts 02 with modified terminal barrier and auxiliary contacts 03 standard, without auxiliary contacts 04 with modified terminal barrier but without auxiliary contacts current ratings 5...100 a 4930 - 01 - 5 a ordering example operating data line (see also mil-prf-83383) voltage ratings u e ac 115 v 400 hz (ac 104...126 v); (operating voltage range) dc 28 v (dc 18...36 v) current rating range i n 5...100 a (see ordering information) bias current typically 2.5 ma at dc 28 v typically 25 ma at ac 115 v switching current/ switching period for internal linear motor typically 3.4 a / 28 ms at dc typically 2.8 a / 17 ms at ac optical indication on/off status indicator (near terminal a1) load circuit load current rating range i n 5...100 a (see ordering information) interrupting capacity dc 28 v: 6,000 a ac 115 v 400 hz: 3,600 a voltage drop at i n see table 1 (standard current ratings and typical voltage drop values) overload disconnection see table 2 (typical time/current characteristics) trip limits see table 2 control circuit icu icu indicator/control unit thermal circuit breaker 0.5 a e.g. 4120-g111-k1m1-a1s0zn-0.5a trigger current for icu (trip free-mode) / duration approx. 3.2 a / 5 s max control voltage u icu limits: rccb off u icu > 2 v (25 c) (icu open) (> 1.5 v between -54...+71 c / -65...+160 f) rccb on u icu < 0.6 v (25 c) (icu closed) (< 0.2 v between -54...+71 c / -65...+160 f) control current i icu typically 0.4 ma additional control units one relay contact or one on/off switch is applicable (see application note icu) on/off-cycling time (e. g. additional relay contact in icu circuit) on > 80 ms / off > 80 ms signal output aux auxiliary contacts change over contacts s1 - s2 is open, when rccb main contact is open voltage ratings dc 28 v, ac 115 v (400 hz) current ratings resistive load: 3 a inductive load 1.5 a lamp load: 0.5 a i n /a e-t-a part number mil part number e-t-a part number mil part number 5 4930-01-5a m83383/02-01 4930-03-5a m83383/01-01 7.5 4930-01-7.5a m83383/02-02 4930-03-7.5a m83383/01-02 10 4930-01-10a m83383/02-03 4930-03-10a m83383/01-03 15 4930-01-15a m83383/02-04 4930-03-15a m83383/01-04 20 4930-01-20a m83383/02-05 4930-03-20a m83383/01-05 25 4930-01-25a m83383/02-06 4930-03-25a m83383/01-06 35 4930-01-35a m83383/02-07 4930-03-35a m83383/01-07 40 4930-01-40a m83383/02-08 4930-03-40a m83383/01-08 50 4930-01-50a m83383/02-09 4930-03-50a m83383/01-09 60 4930-01-60a m83383/02-10 4930-03-60a m83383/01-10 75 4930-01-75a m83383/02-11 4930-03-75a m83383/01-11 80 4930-01-80a m83383/02-12 4930-03-80a m83383/01-12 100 4930-01-100a m83383/02-13 4930-03-100a m83383/01-13 authority standard voltage ratings current ratings dscc mil-prf-83383 ac 115 v, 400 hz dc 28 v 5 a100 a 5 a100 a remote control circuit breaker 4930 (rccb) www.e-t-a. de 1646 1
