Product details

MCCB for distribution panels — 16 A, 10 kA, 4P

The G12T4F16 is a GoPact MCCB 125 4-pole thermal-magnetic circuit breaker rated 16 A at 40 °C with a 10 kA breaking capacity at 415 V AC (380/415 V AC performance level). It uses a TM-D trip unit providing LI protection — thermal for overload (L) and magnetic for short-circuit (I).

The 4-pole (4D) configuration with neutral protection set at 1 x Ir is typical for three-phase + neutral systems. Thermal-magnetic trip technology gives a fixed time-current curve; no electronic adjustment.

Fixed-mount circuit breaker with backplate mounting. Screw terminals on both front-facing upside and downside connections with a 25 mm connection pitch. Accepts horizontal or vertical mounting flat on the back. Dimensions: 100 mm wide, 130 mm high, 60 mm deep.
