Product details

The 2-module-width body (36 mm) snaps onto standard DIN rail; mounting position is unrestricted. Rated for residential and infrastructure duty.

Current lifecycle stage per the manufacturer — no phase-out or NRND notice on record.

Panel integration: 36 mm wide (2 MW), 76 mm depth, 70 mm installation depth. Sealable housing; halogen-free and silicon-free construction. Degree of pollution 2, overvoltage category III.

Thermal derating matters for panel fill: at 30 °C ambient the breaker carries the full 2 A; at 40 °C it derates to 1.92 A, at 45 °C to 1.88 A, at 55 °C to 1.79 A. Mechanical service life 10 000 operating cycles typical. Accepts auxiliary and signaling add-ons (product extension installable supplementary devices).
