Product details

The 3VA1112-4EE36-0AA0 delivers 121 kA at 240 V and 75.6 kA at 415 V — that SCCR covers most transformer-fed distribution panels and motor control centres without needing a current-limiting fuse upstream.

Thermal-magnetic release and current ratings

Panel fit and mounting constraints

The 3-pole frame measures 130 mm high × 76.2 mm wide × 70 mm deep — a standard 3-inch wide footprint that fits most 600 mm wide distribution boards with room for side-by-side mounting. Front IP40 protection means the breaker face is sealed against tools and solid objects >1 mm, but the rear terminals are open to the enclosure — plan for a dead-front panel or terminal shrouds.

Sourcing and production status

Maximum power loss is 28.1 W at rated load — account for this in the enclosure thermal budget, especially in a multi-breaker panel with limited ventilation.
