Discrepancy Switches (ø20 & ø30mm)
| APPLICATION AND USE FRMM6 micro-sender-switches are mounted on switchboards and in telephonic and electric fields, where small currents are required. Suitable for control & indication of circuit breakers, disconnectors, contactors & electro valves. DESCRIPTION AND CONSTRUCTIONAL FEATURES OF THE UNIT. » Front plate: round 25mm dia, or square shaped with 25mm sides. » Contacts: moving and stationary. Moving contacts are mounted on the control shaft. The stationary contacts are mounted on the melamine block either by soldering or with stand clamps for electric wire connection. » Lamp holder: BA7S lamp for 24, 48, 60Vdc, with bayonet cap; Additional resistances are fitted for lamps when different voltages are required; » Trip system: allows 2 to 4 positions. The positions supplied by micro sender-switches are the same as for type FRM 10. FRMM 6 micro-sender-switches allow all connections as previously specified for FRM 10 switches except the ones requiring dragging effect. (FRM 10T). RATED ELECTRICAL CHARACTERISTICS Type FRMM 6l Thermal current Ith = 12A Insulation voltage Ui = 690V ¤ Utilization categories AC14 | AC15 | DC14 ¤ Operational voltage (Ue) 400V | 400V | 110V ¤ Operational Current (Ie) 10A | 6A | 3,5A Conditioned short-circuit current Maximum peak current ≤ 1400A Joule integral (I²t) ≤ 30kA²s DECLARATION OF CONFORMITY TO EN 60947-5-1 STANDARDS. All the FRMM 6 models comply with the requirements of EN 60947-5-1 standard. Thus they also conform to EC directives n° 73/23, 93/68, 89/3396 (EMC), (low voltage directive). TYPE TEST CARRIED OUT IN CESI LABORATORIES MILAN No MP-94/032850. INSTALLATION Apart from boring, patterns shown in the following pages, the installation process of the FRMM 6 is the same as that for FRM 10. Also available as key switches & selector switches. |

| APPLICATION
AND USE FRM 10 sender-switches are suitable for switch board mounting They are used for operation and for position control of disconnectors and circuit-breakers. They can also send short impulses mainly for remote controlling of contactors, electro-valves etc. DESCRIPTION AND CONSTRUCTIONAL FEATURES OF THE UNIT. » Control handle made of nylon varnished black. The handle has a slot housing a transparent screen through which diffusion of light is allowed. » Front plate, round 40mm dia, or square shaped with 40mm sides, made of a light black alloy. » Contacts: moving and stationary. Either thickly silver-plated or gilded upon request as for FR 10. » Lamp holder: BA9S type additional resistances are fitted for lamps when different voltages are required. These are mounted on a switch -unit, and fastened by the clamps of same unit. » Trip system allows 2 to 4 positions. FRMM 6 micro-sender-switches allow all connections as previously specified for FRM 10 switches except the ones requiring dragging effect. (FRM 10T). RATED ELECTRICAL CHARACTERISTICS Type FRM 10 Thermal current Ith = 20A Insulation voltage Ui = 690V Utilization categories: AC 14 | AC 15 | DC 14 Operational voltage (Ue): 400V | 400V | 110V Operational current (Ie): 16A | 10A | 6A Conditioned short-circuit current Maximum peak current ≤ 1500A Joule integral (I²t) ≤ 30kA²s DECLARATION OF CONFORMITY TO EN 60947-5-I STANDARD. All the FRM 10 models comply with the requirements of EN 60947- 5-I standard. Thus they also conform to EC directives n° 73/23, 93/68, 89/336 (EMC), (low voltage directive). TYPE TEST CARRIED OUT IN CESI LABORATORIES MILAN No94/034529 INSTALLATION After suitable boring of panels (see boring patterns in the following figures) proceed as follows: » Remove knob and front plate from switch » Fit switch in from rear of panel » Insert the knob ensuring that the displacements are correctly positioned. » Replace front plate up to thread end » Position switch metal ring to panel and tighten fastening screws. » The panel thickness can range from 2 to 10 mm.
