ABB TMP3SB10R

The ABB TMP3SB10R is a solid choice when you need a reliable main breaker module for metering applications. This modular unit handles up to 1000 amps and supports both single-phase (3-wire, 120/240 V AC) and three-phase (4-wire, 208Y/120 V AC) power setups. It’s rated for a hefty 100 kAIC, so it’s built to stand up to demanding electrical environments. The breaker is included, and the design features line and load lugs that can accommodate 4 sets of 250 to 500 MCM cables, with the option to feed from either the top or bottom—making installation pretty straightforward. If you're looking to beef up your metering setup, this ABB module, distributed by BSP Automation, is definitely a no-brainer.
