Product details

What this MCCB carries and what it means

The 3VA1112-5EF36-0JA0: Breaking capacity is 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500/690 V. For a 3-pole line-protection breaker, the 187 kA at 240 V is high — it can handle fault currents from large transformers or utility feeds without needing a current-limiting fuse upstream. The overcurrent release is TM240 (thermal-magnetic, 240 A frame), and the auxiliary release is a shunt trip (STL) — a separate control voltage trips the breaker remotely. No undervoltage release, no ground-fault monitoring, no communication function. Insulation voltage rated 800 V.

Panel fit and mounting

Dimensions: 130 mm high, 76.2 mm wide, 70 mm deep. Three-pole width is standard for a 125 A frame. No trip indicator on the front face. Operating temperature range -25 °C to +70 °C; storage from -40 °C to +80 °C. Maximum power loss 28.1 W.
