Product details

The G12T4F32: Rated operational voltage is 415 V AC at 50/60 Hz, with a rated insulation voltage of 440 V AC — both conforming to EN/IEC 60947-2. This is the standard curve for general distribution — no electronic adjustability, but reliable and field-proven.

Fixed mounting on a backplate, with front-facing screw terminals for both line and load connections. Neutral is on the left, and the breaker can be mounted horizontally or vertically flat on the backplate — useful for tight enclosures where orientation is constrained.

The G12T4F32 carries IP20 finger protection (IEC 60529), suitable for installation inside a closed panel. Overvoltage category III qualifies it for fixed-installation distribution boards. Electrical durability is rated at 8000 cycles at 415 V at rated current; mechanical durability at 30,000 cycles.
