The 5SJ4213-7HG42: The 2-pole design switches both line conductors in a single-phase or split-phase circuit — no neutral conductor switching. Insulation voltage (Ui) is 440 V AC, which sets the bus-bar spacing requirement inside the distribution board.
Depth is 70 mm, height 121 mm. The combined terminal design at top and bottom accepts both bus-bar fork and screw-clamp wiring; terminal torque spec is 3.5 Nm.
Design engineers need to ensure the breaker can handle available fault current to meet code and safety requirements.
UL listing is critical for regulatory compliance and acceptance by inspectors in North American installations.
Buyers need price to compare budgets and negotiate with suppliers.
Sourcing buyers need immediate distributor availability to fulfill BOM lines without delays.
Maintenance techs and buyers need cross-reference alternatives when original part is not in stock or obsolete.
Project planners need lead time to schedule installations and avoid production downtime.
