Transcription

1 Circuit protection For i DPN (DPN), C60 and C120 Function They remotely trip or indicate circuit-breakers, with or without Vigi module. Description b They are mounted to the left of the circuit-breaker within a maximum width of 54 mm. b Fixed using clips (no tools) onto the left side of the circuit-breaker. Auxiliary combination 54 mm max. Auxiliaries Releases N SD/ SD fault indicating switch MX+, MX, or MSU MN, MNs, or MNx Circuit-breaker b A maximum of 3 indication auxiliaries, SD on the same circuit-breaker. b A maximum of 2 changeover auxiliaries (+SD/) on the same circuit-breaker. b A maximum of 1 +SD/ switchover and 1 indication or SD on the same circuit-breaker. b A maximum of 2 tripping auxiliaries (MX+, MX, MN, MNs, MNx) on the same circuit-breaker. b A maximum of 3 tripping auxiliaries MSU on the same circuit-breaker without other E_Ver3.2.fm/2 28 novembre :28

2 Earth leakage protection For ID and I-NA Function They remotely indicate or trip residual current circuit-breakers. Description b They are mounted to the left of the residual current circuit-breaker using the.s within a max. width of 45 mm. ID combination 45 mm max. Auxiliaries (1) (1) Releases ref D1 +SD/ SD fault indicating switch MX+, MX, or MSU MN, MNs, or MNx.S Residual current circuitbreaker I-NA combination 45 mm max. Auxiliaries (1) (1) Releases D SD/ SD fault indicating switch MX+, MX, or MSU MN, MNs, or MNx I-NA residual current b A maximum of 2 indication auxiliaries on the same residual current circuit-breaker. b A maximum of 1 switchover (+SD/) on the same residual current circuit-breaker without other, SD. b A maximum of 2 tripping auxiliaries MX+, MX, MN, MNs, MNx or MSU on the same residual current circuit-breaker. (1) Be careful: SD and +SD/ s must be only mounted to the left of a tripping (MN, MX, MSU,...). 28 novembre : E_Ver3.2.fm/3

3 I-NA MX+ Tripping Tripping indication on front panel by means of a red indicator. b Auxiliaries conforme standard IEC MX + shunt trip release Controls tripping of the device with which it is combined when energised. He is fitted out with a changeover (O + C) to indicate the circuit-breaker's position. It is fitted with a self-interrupting allowing the control circuit to remain on (latching emergency stop). PB MX shunt release Controls tripping of the device with which it is combined at power-up. It is fitted with a self-interrupting allowing the control circuit to remain on (latching emergency stop). PB MX MN release Controls tripping of the device with which it is combined when its supply voltage drops (threshold between 70 and 35 % of the Un). It allows the device to be manually closed if the voltage exceeds 85 % of the nominal voltage. b Use: v emergency stop pushbutton v safety on supply circuits of several machines by preventing the "non-controlled" restart of all the motors. MN MN sélectif s MN selective s release Undervoltage release that controls the opening of the device with which it is combined. 0.3 s time-delay on voltage dip: avoids tripping on brownouts or momentary voltage drops. PB PB MNx MNx release for pushbutton with opening Completely insensitive to supply circuit interruptions. It is recommended to connect it upstream of the circuit-breaker it protects in the event of fail-safe emergency stops. Replaces the "volontary" MX release fitted out with O/F indicators. MSU voltage threshold release Especially designed to monitor the voltage between the neutral and phase(s) conductors. It cuts off the supply by opening the protected device when a threshold level for overvoltages lasting more than a few tenths of a second is exceeded. Connection b Using screw clamp terminals: v for 1 or 2 cables of a max. of 2.5 mm 2 v 1.5 mm 2 with end. b Visible markers near the terminals. MSU 90142E_Ver3.2.fm/4 28 novembre :28

4 I-NA (cont.) Remote indication b All s conform to standard IEC b The s, SD, +SD/ are also conform with standard EN for C60, C120 and i DPN (DPN). SD open/closed b Changeover that indicates the "open" or "closed" position of the device. b Test button on front panel enables verification of the indication circuit, without having to operate the device. SD fault indicating switch b Changover that indicates the "tripped" position of the device. b Fault indication (SD) on front panel by means of a mechanical indicator. b Always mount to the left of one or more tripping auxiliaries. +SD/ changeover b Double changeover indicates: v the open or closed position of the circuit-breaker () v the tripped position of the device (SD). b 2 circuits: v upper: v lower: SD or. b Function choice using the rotary changeover switch on the right side. b Selected function is indicated on the front panel. b Fault indication (SD) on front panel by means of a mechanical red indicator. b Always mount to the left of one or more tripping auxiliaries. REF SD/.S for ID b Use of the.s is mandatory when adding tripping and indication functions on a residual current circuit-breaker. b This is mounted to the left and indicates the "open" or "closed" position of the residual current circuit-breaker. Connection b Using screw clamp terminals: v for 1 or 2 cables of a max. of 2.5 mm 2 v 1.5 mm 2 with end. b Visible markers near the terminals..s 28 novembre : E_Ver3.2.fm/5
