Status Indications and Remote Control
When the circuit breaker is equipped with the Breaker Communications Module (BSCM), the FDM121
display can also be used to view circuit breaker status conditions:
• O/F: ON/OFF
• SD: trip indication
• SDE: fault-trip indication (overload, short-circuit, or ground fault).
When the circuit breaker system is equipped with the I/O application module, the FDM121 can monitor
and control:
• cradle management
• circuit breaker operation
• light and load control
• custom applications.
When the circuit breaker is equipped with the communication motor operator etc., the FDM121 display
can also be used to control (open/close) the circuit breaker.
Two operating mode are available:
• local mode: open/close commands are enabled from the FDM121 while disabled from the
communication network;
• remote mode: open/close commands are disabled from the FDM121 while enabled from the
communication network.
Main Characteristics
• A 3.78 x 3.78 x 1.18 in. (96 x 96 x 30 mm) screen requiring 0.39 in. (10 mm) behind the door (or
0.79 in. [20 mm] when the 24 V power supply connector is used).
• White backlighting.
• Wide viewing angle: vertical ±60°, horizontal ±30°.
• High resolution: excellent reading of graphic symbols.
• Alarm LED: flashing orange for alarm pick-up, steady orange after operator reset if the alarm
condition persists.
• Operating temperature range: +14°F (-10°C) to +131°F (+55°C).
• CE / UL / CSA marking.
• 24 Vdc power supply, with tolerances 24 V -20% (19.2 V) to 24 V +10% (26.4 V).
When the FDM121 is connected to the communication network, the 24 Vdc can be supplied by the
communication system wiring system. Consumption is 40 mA.
Mounting
The FDM121 is easily installed in a switchboard.
• Standard door cut-out is 3.6 x 3.6 in. (92 x 92 mm).
• Attached using clips.
To avoid a cut-out in the door, an accessory is available for surface mounting by drilling only two
0.87 in. (22 mm) diameter holes.
