ABB Debuts Miniature Circuit Breaker

Melissa Larson | July 15, 2015

The new SU 200 M miniature circuit breaker (MCB) from ABB offers an extended rating of 40 amps at 277Y/480 volts AC to protect larger loads, a dual AC/DC rating to reduce the number of SKUs required for inventory, and a more durable housing to help prevent damage during shipping and handling.

The SU 200 M MCB, part of ABB’s System pro M compact MCBs, offers extended AC and DC ratings up to 40 amps at 480Y/277 volts AC (C and Z trip curves), the highest amperage level available in the industry. The DC ratings are 48 volts for single-pole and 96 volts for multi-pole applications. The dual AC and DC ratings allow for a reduction in inventory.

SU 200 M MCBs have a reference temperature at 40 degrees Celsius (104 degrees Fahrenheit), in accordance with Underwriters Laboratories (UL) and the Canadian Standards Association (CSA), for use in enclosures, panel boards and other warm-environment applications.
