DETAILED DESCRIPTION

Miniature circuit breakers 1.000 V DC

General characteristics

The miniature circuit breakers for photovoltaic applications type P1MD... are designed to protect against overloads and short circuits the cables located between the photovoltaic panel strings and the inverter.
In addition to photovoltaic applications, these devices can be used for other DC-1 loads, such as non-inductive or slightly inductive loads.
Main features include:
– Rated current from 16A to 50A
– IEC breaking capacity Icu 5kA 1000VDC
– Contact status with flag indicator
– Tripping characteristic: curve type B
– Accessories available: auxiliary contacts, shunt trips and undervoltage releases.
Operational chacteristics
– Rated insulation voltage Ui: 1000V
– Rated impulse voltage Uimp: 4kV
– Mechanical life: 20.000 cycles
– Mounting on 35mm DIN rail (IEC/EN/BS 60715)
– Mounting position: any
– Utilization category: A.
Compliance:
Compliant with standard IEC/EN/BS 60947-2.
