It delivers a breaking capacity of 60 kA Icu at 220/240 V AC and 30 kA Icu at 380/400 V AC, both per IEC 60947-2. This is a distribution-grade MCCB suited for backplate mounting in panelboards and switchboards.
At the common 400 V distribution level it still holds 30 kA Icu, which coordinates well downstream of a larger main breaker or fused switch. The 63 A rating and category A utilisation make it a straightforward fit for feeder or branch protection in a 400 V panel.
The TM-D trip unit provides fixed long-time delay at 1 In and a magnetic short-circuit pickup. Overload protection is thermal; short-circuit protection is magnetic. The integral instant protection is rated 750 kA. The breaker is also suitable for isolation — a lockable toggle handle gives visible break confirmation.
Fixed mounting on a backplate, with front-front connections (both line and load terminate on the front face). Width is 75 mm, depth 60 mm, height 130 mm — three of these sit comfortably on a 300 mm wide backplate with space for neutral links. Neutral is on the left, protected poles are 3D (all three poles protected). IP40 front face, IK07 impact resistance.
