Weidmuller introduces their new line of DIN-rail mounted, thermal magnetic miniature circuit breakers (MCB) - the BR and SU Series. This new MCB line offers a complete range of UL 489 listed Branch circuit breakers and UL 1077 listed Supplementary circuit breakers, all rated for both AC and DC circuits. Well suited for use in environments where the control equipment may be subjected to vibration and mechanical shock, the BR and SU Series provide downstream protection for circuit cables, motors, generators, transformers, computer systems, power supplies and telecommunications equipment in industries worldwide.
The BR and SU Series MCBs are equipped with a trip-free, snap action toggle and easy visual status indication. At 17.6mm wide (one-pole), they are available in one-, two- and three-pole versions with an amperage range up to 63A, and in B, C, or D trip curve options to meet application needs. This series covers a wide voltage range of 120/240/277/480Vac and 60/125Vdc for single-pole and double-pole versions. A high-rated interrupting capacity of 10kA makes them ideally suited for branch protection applications.
A wide range of easy-to-connect accessories are available to round-out the BR and SU Series. These include control and monitoring attachment modules such as auxiliary contacts, bell alarm contacts and shunt trips, as well as cuttable busbars and busbars accessories that comply with UL standards.
