S800 PV MCBs
S800 PV-S miniature circuit-breakers and S800 PV-M switch disconnectors can be used in networks up to 1200
V d.c. (four-pole version). These products and their vast range of accessories (auxiliary contacts, release coils) can
be used to create countless system configurations. The main features of S800 PV-S circuit-breakers are:
- interchangeable terminals
- fault signalling lever in the central position
- contact status displayed for each individual pole
- no restrictions as to polarity or power direction in the wiring
- use of the rotary door operating handle
OT Isolators
OT series disconnectors are available with 16 A to 125 A rated current values in 3, 4, 6 and 8 pole versions,
depending on the direct current voltage used.
The main features of OT disconnectors are:
- quick make-break mechanism with independent tripping function (in the OT 45...125 versions).
- accessories that are snap-fitted on the circuit-breakers
- OT 45 ... 125 switch-disconnector mechanism for installation on DIN channel.
- can be locked with a locking adapter
Tmax PV Disconnector
Tmax PV series disconnectors are available with up to 1600 A class DC-22B rated operating current values, for
1100 V d.c. maximum rated operating voltage. The switching devices of the Tmax PV series are the first box
disconnectors for direct current high voltage available on the market. They are certainly of interest for use in any
type of photovoltaic installation since they are ideal for all disconnecting requirements.
The main features of Tmax PV disconnectors are:
- Comprehensive range. There are 6 different sizes, from the compact T1 (which can be fixed to DIN channel) to
T7, available in the two versions with operating lever and motor control
- Excellent performance-dimensions ratio
- Wide choice of accessories to suit every requirement
