What this MCCB delivers
The Siemens SENTRON 3VA1010-3ED42-0JH0 is a 4-pole molded case circuit breaker rated for 100 A continuous at 40 °C, with a maximum breaking capacity of 75.6 kA at 240 V. That breaking figure drops to 52.5 kA at 415 V and 32 kA at 440 V, so the voltage on your line determines whether this frame clears a high-fault scenario or needs upstream coordination. The 100 A rating holds steady through 50 °C; above that it derates to 98 A at 55 °C and 91 A at 70 °C, which matters if the breaker sits in a warm enclosure alongside other heat sources.
Line protection and auxiliary fit
This variant is designed for line protection — it's the feeder or main breaker role, not motor-circuit protection with an integrated overload. The trip indicator and voltage trigger are built in.
Panel fit and environment
Footprint is 101.6 mm wide by 130 mm tall by 70 mm deep — a 4-pole frame that fits standard MCCB mounting in a distribution board.
