If the distribution board runs warm — say, a packed enclosure near a drive cabinet — use the 40 °C figure for your continuous load calculation.","metaTitle":"Siemens 5SU9356-7KN63 SENTRON RCBO, 63 A, 30 mA, Type A, C-c","metaDescription":"Siemens 5SU9356-7KN63 SENTRON RCBO, 63 A rated, 30 mA residual current, Type A, C-curve, 6 kA per EN 60898, 2-pole, 2 MW.

The 5SY5250-7 and 5SY5240-7 are MCBs only — no residual current protection. No direct drop-in replacement exists without rewiring or re-rating the circuit."},{"question":"What compliance documentation does this brand provide for 5SU9356-7KN63?","answer":"The RCBO carries an EN 60898 rating (6 kA interrupting capacity) and an overvoltage category III rating with pollution degree 2. The SENTRON series typically ships with CE and UKCA declarations; specific RoHS/REACH statements are available from the manufacturer on request."},{"question":"Where can I buy 5SU9356-7KN63 and how is it quoted?","answer":"Sourced and quoted to order against an RFQ through independent industrial-automation distribution.
