Product details

Breaking capacity is 10 kA Icu at 1000 V DC with four poles in series, per EN/IEC 60947-2.

In a hot rooftop combiner box, derate above 40 °C per the thermal curve. The 1000 V DC rated operational voltage matches the maximum system voltage for many commercial PV installations; insulation voltage is also 1000 V DC. IP40 front protection keeps tools and fingers out; IK07 impact rating handles accidental knocks during installation.

Front connections top and bottom — 45 mm pole pitch. Toggle control, no aux contacts in the base unit. Depth is 110 mm, width 185 mm, height 255 mm. Fits standard PV combiner enclosures; plan for front-access wiring clearance.
